Abstract
Background This was an experimental, parallel, and randomized study to evaluate the safety of single intracameral injection of 0.6 ml 0.5% preservative-free levofloxacin eye drops on rabbit eye. Methods In total, 24 eyes of 12 New Zealand white rabbits were divided into three groups. The first group (LFX) was treated with 0.1 ml intracameral injection of levofloxacin 0.5% eye drops of 0.6 ml preservative-free (n = 6), the second group (CRAV) was treated with 0.1 ml intracameral injection of levofloxacin 0.5% eye drops 5 ml commercially available eye drops preservative-free (n = 6), and the third group (BSS) were treated with 0.1 ml intracameral injection of balanced salt solution (n = 12). All groups received a single dose. The clinical evaluation was performed on the 1 st, 3 rd, 5 th, and 7 th day after injection. Each eye was enucleated on the 7 th day and underwent a histopathology examination. Results The clinical scores among the three groups did not show any significant difference on days 1 st, 2 nd, 3 rd, and 7 th (p>0.05). The only ones noted in clinical scores were mild corneal opacity, mild cells, and flares in the anterior chamber. The histopathology score demonstrated no statistically significant difference between the three groups (p>0.05). Vacuolization of corneal endothelial cells was noted in all groups but was not statistically significant. Conclusions A single intracameral injection of 0.6 ml 0.5% preservative-free levofloxacin eye drops was safe for rabbit eye, according to clinical and histopathology scores, similar to levofloxacin 0.5% eye drops in 5 ml bottle preservative free.

Moxifloxacin Liposomes: Effect of Liposome Preparation Method on Physicochemical Properties and Antimicrobial Activity against Staphylococcus epidermidis. Pharmaceutics 2022; 14:pharmaceutics14020370. [PMID: 35214102 PMCID: PMC8875207 DOI: 10.3390/pharmaceutics14020370] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Revised: 01/27/2022] [Accepted: 02/01/2022] [Indexed: 12/16/2022] Open
Abstract
The aim of this study was the development of optimal sustained-release moxifloxacin (MOX)-loaded liposomes as intraocular therapeutics of endophthalmitis. Two methods were compared for the preparation of MOX liposomes; the dehydration–rehydration (DRV) method and the active loading method (AL). Numerous lipid-membrane compositions were studied to determine the potential effect on MOX loading and retention in liposomes. MOX and phospholipid contents were measured by HPLC and a colorimetric assay for phospholipids, respectively. Vesicle size distribution and surface charge were measured by DLS, and morphology was evaluated by cryo-TEM. The AL method conferred liposomes with higher MOX encapsulation compared to the DRV method for all the lipid compositions used. Cryo-TEM showed that both liposome types had round vesicular structure and size around 100–150 nm, while a granular texture was evident in the entrapped aqueous compartments of most AL liposomes, but substantially less in DRV liposomes; X-ray diffraction analysis demonstrated slight crystallinity in AL liposomes, especially the ones with highest MOX encapsulation. AL liposomes retained MOX for significantly longer time periods compared to DRVs. Lipid composition did not affect MOX release from DRV liposomes but significantly altered drug loading/release in AL liposomes. Interestingly, AL liposomes demonstrated substantially higher antimicrobial potential towards S. epidermidis growth and biofilm susceptibility compared to corresponding DRV liposomes, indicating the importance of MOX retention in liposomes on their activity. In conclusion, the liposome preparation method/type determines the rate of MOX release from liposomes and modulates their antimicrobial potential, a finding that deserves further in vitro and in vivo exploitation.

Ocular surface flora and prophylactic antibiotics for cataract surgery in the age of antimicrobial resistance. Jpn J Ophthalmol 2022; 66:111-118. [PMID: 35006494 DOI: 10.1007/s10384-021-00899-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 09/13/2021] [Indexed: 10/19/2022]
Abstract
According to the World Health Organization alert about the antimicrobial resistance crisis released in 2015, clinicians should strongly reconsider the prolonged use of antimicrobials. In this review, we focus on the ocular surface flora with respect to the trend of fluoroquinolone resistance, and its upset and restoration after topical administration of antimicrobials and preservatives. Even 3 weeks of topical administration of levofloxacin (LVFX) yields a selection of fluoroquinolone-resistant isolates bearing genetic changes in the ocular surface flora. One month of topical prophylactic administration of LVFX after cataract surgery induces the loss of diversity with LVFX-resistance of the ocular surface flora. Restoration of LVFX-sensitive flora occurs 6 to 9 months after the final topical administration of LVFX. The ocular surface flora recovers earlier in patients given LVFX for 1 week after the surgical procedure. These findings suggest that shorter periods of postoperative topical antibiotics are less frequently associated with persistent antimicrobial-resistant bacteria in the ocular flora. In addition, microbiologic analysis of ocular surfaces treated with a long period of eye drops containing benzalkonium chloride (BAC) showed a higher incidence of isolates resistant to methicillin and fluoroquinolones than did ocular surfaces treated with eye drops not containing BAC. To avoid the emergence of antimicrobial-resistant bacteria on the ocular surface, an urgent discussion must be held about the appropriate use of antibiotics and preservatives in the ophthalmology field.

Abstract
PURPOSE To determine any changes in macular or choroidal thickness associated with the use of intracameral moxifloxacin as postcataract endophthalmitis prophylaxis. SETTING University of Campinas, Campinas, São Paulo, Brazil. DESIGN Prospective, randomized, partially masked, single-site clinical trial. METHODS Phacoemulsification surgery patients in the experimental group (Group A) received a 0.03 mL intracameral injection of undiluted moxifloxacin from a sealed bottle immediately after phacoemulsification surgery (150 μg in 0.03 mL-Vigamox solution), whereas the control group (Group B) did not. Investigators evaluated in masked fashion macular and choroidal thickness using spectral-domain optical coherence tomography preoperatively and postoperatively. RESULTS A total of 93 patients were included (48 in Group A and 45 in Group B). Baseline parameters were similar between the groups. Either of the 2 parameters assessed differed statistically between the groups or preoperatively vs postoperatively. On postoperative day 30, central macular thickness was 8.85 ± 14.78 μm in Group A and 10.26 ± 22.44 μm in Group B (P = .7232); choroidal thickness as measured by enhanced depth imaging (EDI) was 1.45 ± 16.13 μm in Group A and 3.74 ± 16.15 in Group B (P = .5017). On postoperative day 60, central macular thickness was 19.53 ± 39.28 μm in Group A and 17.14 ± 53.68 μm in Group B (P = .8363); EDI was 5.08 ± 21.96 μm in Group A and 5.24 ± 15.8 in Group B (P = .9752). CONCLUSIONS The application of intracameral injection of 0.03 mL of undiluted 0.5% moxifloxacin during phacoemulsification surgery as endophthalmitis prophylaxis induced no changes in macular or choroidal thickness.

Abstract
PURPOSE To estimate the association of cefuroxime and moxifloxacin in relation to the occurrence of endophthalmitis following phacoemulsification cataract surgery. DESIGN Retrospective clinical cohort study. METHODS We studied patients with noncomplex phacoemulsification cataract surgery in Kaiser Permanente Northern California during 2014-2019. Data were obtained for acute, postoperative endophthalmitis within 90 days of phacoemulsification, including culture and antibiogram results, intracameral and topical antibiotic agent, and dose. In a post hoc analysis, we also examined preoperative anterior chamber depth (ACD) and postoperative anterior chamber volume (ACV). RESULTS Of 216,141 surgeries, endophthalmitis occurred in 0.020% of moxifloxacin-injected eyes and 0.013% of cefuroxime eyes (relative risk 1.62 with 95% CI 0.82-3.20, P = .16). Of the 34 (0.016%) cases of endophthalmitis, cefuroxime 1 mg was injected into 13 eyes and moxifloxacin 0.1% into 21 eyes. Organisms with antibiograms were identified in 12 (35%) cases. Of these, bacteria recovered from cefuroxime-injected eyes were resistant to cefuroxime in all cases (4/4), with Enterococcus comprising half of these. In eyes injected with moxifloxacin 0.1%, 6 out of 7 organisms were sensitive to moxifloxacin injected with 0.1 mL and in 1 eye injected with 1 mL. Streptococcus was the most common organism recovered (6/9) in moxifloxacin-injected eyes. Preoperative ACD and postoperative calculated ACV were higher in eyes injected with moxifloxacin. CONCLUSIONS Endophthalmitis cases with positive cultures were generally related to organism resistance in cefuroxime eyes but to sensitive organisms in moxifloxacin eyes. Moxifloxacin doses may have been insufficient in eyes with larger ACV.

Abstract
Objective This study was conducted to understand the effects of intracameral moxifloxacin in decreasing the incidence of postoperative endophthalmitis after cataract surgery in an eye hospital with a high volume surgical load. Methods and analysis In this single-centre, retrospective, clinical registry-based study, we compared the rates of postoperative endophthalmitis in 31 340 cataract surgery patients operated during 22 months after June 2018 who received intracameral moxifloxacin to 80 643 patients operated during 41 months before June 2018 who did not receive intracameral moxifloxacin. All patients received subconjunctival gentamycin and dexamethasone. Combined surgical procedures were excluded from the study. Results There was a significant reduction (p<0.001) of postoperative endophthalmitis rates in cataract surgeries from 0.144% (116/80 643) to 0.025% (8/31 340) after initiation of intracameral moxifloxacin. Endophthalmitis rates decreased from 0.120% (12/9942) to 0.009% (1/10 787) in phacoemulsification group and from 0.147% (104/70 701) to 0.034% (7/20 553) in manual small-incision cataract surgeries. Gram-positive organisms including Coagulase-negative staphylococci (37.9%, n=11) and Staphylococcus aureus (S. aureus 34.5%, n=10) were the most common organisms isolated out of 29 culture-positive cases. 24.1% (28/116) endophthalmitis cases in group without moxifloxacin were culture positive compared with 14.3% (1/7) of cases in moxifloxacin group. 72% (n=8) of the Coagulase-negative staphylococci and 80% of S. aureus isolates (n=8) showed in vitro sensitivity to moxifloxacin. Conclusion Prophylactic use of intracameral moxifloxacin injection in addition to subconjunctival gentamycin in cataract surgery is associated with a significant decrease in rates of postoperative endophthalmitis when compared with the use of subconjunctival gentamycin alone in high volume settings.

Abstract
Objective Intended to investigate the epidemiological characteristics, risk factors and incidence trend of endophthalmitis after cataract surgery in recent 12 years. Methods A retrospective study was conducted on the patients who underwent cataract surgery in Qingdao Eye Hospital from January 1, 2008, to December 31, 2019, including age, sex, history of diabetes, intraoperative operation and complications. In addition, the related risk factors and incidence trend of acute infective endophthalmitis were analyzed. The incidence of endophthalmitis and its related factors were analyzed by univariate and multivariate logistic regression analysis. Results A total of 55,612 cases of cataract surgery were performed in our hospital in 12 years, and 42 cases of acute infective endophthalmitis occurred (the incidence rate was 0.076%). The average occurrence time was 10.57 days ± 11.17, with eye pain as the main complaint and anterior chamber fibrin exudation as the main clinical manifestation. In addition, there were eight cases of anterior chamber hypopyon and 18 cases of vitreous reaction, the results of anterior aqueous humor or vitreous fluid culture in 10 patients were positive. Univariate analysis showed that intraoperative rupture of posterior capsule, non-use of antibiotics and non-use of behind-the-lens washout were the risk factors of infectious endophthalmitis after cataract surgery (P=0.032, P=0.000, P=0.000). Besides, multivariate logistic regression analysis showed that intraoperative rupture of posterior capsule was the main risk factor. Conclusion The occurrence of endophthalmitis after cataract surgery is mainly related to intraoperative rupture of posterior capsule, absence of antibiotics and behind-the-lens washout. In addition, the incidence of endophthalmitis after cataract surgery decreased during the past 12 years.

Abstract
PURPOSE To investigate whether the safety of intracameral moxifloxacin (IC-Mox) was equivalent to subconjunctival antibiotics (SC-Abs) in pediatric lens surgery. SETTING The Hospital for Sick Children, Toronto, Canada. DESIGN Retrospective consecutive cohort study. METHODS This equivalence study compared 95% CI in the difference between the preoperative and postoperative safety variables of best corrected visual acuity (BCVA), intraocular pressure (IOP), central corneal thickness (CCT), endothelial cell density (ECD), corneal edema, and anterior chamber (AC) inflammation in IC-Mox with SC-Abs. The zone of clinical equivalence for BCVA was set at ±0.2 logarithm of the minimum angle of resolution, IOP at ±3 mm Hg, CCT at ±30 μm, and ECD at ±400 cells/mm. RESULTS The charts of 358 patients undergoing lens-related surgeries were reviewed. Of 317 eyes (215 patients) included, 170 eyes received IC-Mox and 147 eyes had SC-Abs. The mean age was 4.9 and 5.1 years with a mean follow-up of 19 and 34.4 months (P < .001) in IC-Mox and SC-Ab groups, respectively. The 95% CIs for the change from preoperative to postoperative safety parameters between IC-Mox and SC-Abs were all in the zones of clinical equivalence (BCVA, P = 0.75; highest IOP in the first 6 weeks postoperatively, P = 0.27; IOP at the last visit, P = 0.74; CCT, P = 0.89; and ECD, P = 0.76). During the first 6 weeks postoperatively, there was no difference in corneal edema (P = .69) and AC flare (P = .4) between IC-Mox and SC-Ab groups, whereas AC cellular activity was significantly higher in the SC-Ab group (P = .028). CONCLUSIONS IC-Mox prophylaxis in pediatric patients showed equivalent postoperative safety outcomes when compared with SC-Abs. The use of IC-Mox (250 μg) for endophthalmitis prophylaxis appears to be safe in the pediatric population.

Abstract
Objective To report the results of a global survey on cataract practice patterns related to preoperative, intraoperative and postoperative care, surgical setting and personnel allocation. Methods and analysis An online 28 questions survey was sent to 240 ophthalmologists asking to describe prevailing trends in their institutions across 38 countries and 5 continents. Questions inquired country, institution, surgical volume and setting, anaesthesia, preoperative and intraoperative examination and postsurgical care. Statistical analysis used crosstabs lambda statistics for non-parametric nominal variables. P value less than 0.05 was considered statistically significant. Results 209/240 (87%) ophthalmologists responded: 38% representing public hospitals, 36% private practices and 26% academic sites; overall surgical volume was between 241 700 and 410 500 cataracts per year. There was a significant correlation between type of institution and surgical volume. Complete results available in online (https://freeonlinesurveys.com/r/W6BcLLxy). Conclusion Cataract surgery related patterns of perioperative care showed significant difference among respondents, regardless to type of institution, surgical volume and country. Many evidence-based procedures are unevenly practiced around the world and some widespread and expensive habits lack solid scientific evidence while consuming enormous amount of resources both monetary and human. There is a need to reach consensus and share evidence-based practice patterns.

Abstract
Purpose To evaluate the clinical outcome following intraoperative transzonular intravitreal injection of triamcinolone acetonide and moxifloxacin in patients undergoing phacoemulsification cataract extraction with intraocular lens (IOL) implantation. Methods In this prospective, non-randomized, clinical, interventional study, a total of 200 eyes were enrolled. Patients who voluntarily gave their consent after being informed about dropless cataract surgery along with its pros and cons were included. Those who had glaucoma or were known steroid responders as well as those who were lost to follow-up were excluded. 0.1 ml each of moxifloxacin (500 mg) and triamcinolone acetonide (4 mg) were injected transzonularly following IOL implantation in phacoemulsification cataract surgery with the help of 27G curved cannula. Slit-lamp examination was done to detect cells, visual acuity was noted, and intraocular pressure was measured postoperatively on day 1, 7, 30, 60, and 90. Results Uncorrected visual acuity (UCVA) greater than 6/9 was achieved in 96% of patients at the end of 3 months. The mean IOP was found to be normal in all the cases at every visit. Twenty patients complained of floaters on postoperative day 1 (D1), which decreased to zero after 60 days (D60). None of the patients needed any eye drop during the entire postoperative period. Conclusion The study demonstrates that this procedure is advantageous and safe.

Abstract
PURPOSE To compare the rate of endophthalmitis of intracameral versus topical antibiotic prophylaxis for patients undergoing phacoemulsification at a single-centered, multispecialty ophthalmological institute. METHODS A retrospective analysis of the rate of endophthalmitis by coding search within 90 days of cataract surgery in periods before (May 15, 2012-May 15, 2014) and after (April 30, 2015-April 30, 2017) intracameral antibiotics became the institution's preferred practice pattern for phacoemulsification. Clinical data were collected for each endophthalmitis case, including timing of onset, presenting symptoms and signs, culture results, treatment performed, and visual acuity outcome. RESULTS The rate of postphacoemulsification endophthalmitis decreased from 0.18% (29 eyes among 16,201 cataract surgeries) to 0.07% (11 eyes among 16,325 surgeries) when the preferred method was changed from topical to intracameral antibiotics (P=0.004) with an odds ratio of 0.32. Endophthalmitis cases in the 2 groups had comparable visual acuity at initial presentation and at 3 months (P=0.86). The most commonly isolated organism in culture-proven cases of endophthalmitis in both groups was coagulase-negative staphylococcus. The rate of gram-positive endophthalmitis decreased from 0.08% to 0.02% with an odds ratio of 0.23 (P=0.012) while the rate of gram-negative cases remained similar. CONCLUSIONS The use of intracameral antibiotics during cataract surgery was associated with a statistically significant reduction of postoperative endophthalmitis.

Abstract
PURPOSE OF REVIEW Routine prophylaxis for adverse events following cataract surgery is evolving. Prior reliance on topical eyedrop instillation by patients is giving way to surgeon directed injections at the time of cataract surgery. The benefit of this new approach is assured delivery of drugs in standardized doses which should optimize the healing process and reduce the incidence of untoward events with higher confidence. RECENT FINDINGS Adoption rates of intracameral antibiotic injection amongst European and American cataract surgeons is increasing. Techniques to inject periocular corticosteroid for routine inflammation prophylaxis are also in development. In combination with intraoperative pharmacologic dilation, a drop-free modality can be achieved. SUMMARY Intraoperative injections offer the patient and surgeon assured drug delivery and hold promise to avoid the pitfalls of patient adherence, incorrect topical instillation, and topical drop-associated corneal issues.

Abstract
PURPOSE To test the effect of injection volume and concentration on dosing and residence time of moxifloxacin in the anterior chamber (AC). SETTING Kaiser Permanente, Walnut Creek, California, USA. DESIGN Experimental study. METHODS Moxifloxacin 0.5%/0.05 mL, moxifloxacin 0.5%/0.10 mL, and moxifloxacin 0.15%/0.50 mL were drawn into 5 1.0 mL syringes each, injected into tared vials, and weighed. The doses delivered were calculated. The AC concentrations and elimination rates of the drug for two AC volumes were modeled for each dosing method. RESULTS The 0.05 mL injection volume resulted in the greatest range (35 μg) of delivered dose compared with larger injection volumes (≤25 μg). The mathematical model predicted that variation in dosing in each group would result in differences of 12 minutes or less for the presence of the drug in the AC. Injection of 0.5%/0.1 mL produced AC concentrations above 500 μg/mL for 1.9 to 3.0 hours and above 64 μg/mL for 5.5 to 6.5 hours, depending on the AC volume; however, flushing with a 0.15% concentration sustained AC levels for 1.9 hours and 5.5 hours, respectively, for the two AC volumes. CONCLUSIONS Smaller injection volumes of a higher concentration moxifloxacin resulted in less accuracy and less precision in the delivered dose (0.05 mL, P = .005; 0.10 mL, P = .03); however, the clinical significance of this might vary. Injection of 0.5%/0.1 mL and flushing with 0.15%/0.5 mL of moxifloxacin would provide similar drug AC residence times according to the model. Flushing provided more consistent AC concentrations with differing AC volumes.

Abstract
Purpose: To compare equal concentrations (0.5%) of moxifloxacin and gatifloxacin ophthalmic solutions with regard to conjunctival bacterial reduction as well as anterior chamber penetration. Methods: One hundred patients were divided into 2 groups. Group A received moxifloxacin 0.5% ophthalmic solution and group B received gatifloxacin 0.5% ophthalmic solution 4 times a day for 3 days before surgery and 5 times with 30 min intervals on the day of surgery. Two conjunctival swabs were obtained: one before instillation of antibiotic and the second 30 min after instillation of the last antibiotic drop. Specimens were sent for culture and susceptibility testing. At the time of surgery, 0.1 mL of aqueous fluid was aspired, and aqueous concentration of fluoroquinolones was identified using reverse-phase high-pressure liquid chromatography assay technique. Results: The most common flora isolated was coagulase-negative Staphylococcus (32.9%), followed by Staphylococcus aureus (24.8%) and Corynebacterium diphtheria (19.1%). Moxifloxacin aqueous concentration was higher compared with gatifloxacin [1.75 ± 0.98 standard deviation (SD) and 0.75 ± 0.22 SD, respectively]. This 2.3-fold difference in aqueous humor antibiotic concentrations was statistically significant (P ≤ 0.001). There was significant difference between the means of conjunctival colony-forming unit after antibiotic administration in both the study groups (2.17 ± 1.54 SD in group A and 1.56 ± 1.09 SD in group B). Conclusions: Moxifloxacin 0.5% was found to penetrate anterior chamber more than gatifloxacin 0.5%, enforcing its use for prophylaxis before intraocular surgeries. However, gatifloxacin 0.5% eye drops were able to reduce conjunctival bacterial load, more supporting its use before extraocular and refractive surgeries.

Abstract
PURPOSE To evaluate the safety and efficacy of intracameral (IC) 0.5% moxifloxacin in the prevention of post-cataract endophthalmitis. SETTING University of Campinas, São Paulo, Brazil. DESIGN Prospective randomized partially masked single-site clinical trial. METHODS Patients who had phacoemulsification were randomized into two groups in block sizes of 4. Group A (moxifloxacin group) consisted of patients who received an IC injection of 0.03 mL (150 μg) of undiluted 0.5% moxifloxacin at the end of surgery. Group B (control group) consisted of patients who received no IC medication. The postoperative prescription for both groups consisted of 0.5% moxifloxacin and 0.1% dexamethasone. Patients were monitored for 6 weeks after surgery. The primary outcome was the incidence of acute endophthalmitis in each group. Secondary outcomes were corrected distance visual acuity (CDVA), endothelial cell density (ECD), intraocular pressure (IOP), and central corneal thickness (CCT). RESULTS The study comprised 3640 eyes from 3640 patients. There were 1818 patients in Group A and 1822 patients in Group B. The incidence of endophthalmitis within 6 weeks of follow-up was 1 (0.05%) of 1818 eyes in the moxifloxacin group and 7 (0.38%) of 1822 eyes in the control group (P = .035). There was no significant difference in CDVA (P = .202), ECD (P = .482), IOP (P = .105), or CCT (P = .558). No ocular or systemic study-related adverse events were observed. CONCLUSIONS The IC injection of undiluted 0.5% moxifloxacin can be safely applied as the last step of phacoemulsification. It was found to be effective in reducing the risk for endophthalmitis. This study represents the first controlled randomized clinical trial to evaluate the safety and efficacy of IC moxifloxacin in the prevention of post-cataract endophthalmitis.

Abstract
Purpose To describe an immunosuppressed patient who developed acute-onset postoperative endophthalmitis caused by a moxifloxacin-resistant strain of Staphylococcus epidermidis after cataract surgery despite the use of intracameral moxifloxacin. Observations A 76-year old woman with a history of birdshot chorioretinopathy controlled on systemic immunosuppression underwent uneventful cataract surgery in her right eye. Compounded intracameral moxifloxacin 0.2 cc of 1mg/0.1mL (Edge Pharmacy, Syracuse, NY) was injected intraoperatively as prophylaxis, and the patient was placed on a standard regimen of trimethoprim-polymyxin b (10000-0.1unit/mL) and prednisolone acetate 1% postoperatively. Four days later, the patient experienced a sudden decrease in vision in the right eye. Anterior chamber inflammation, vitritis, and vasculitis were seen in the operated eye. The patient underwent a vitreous tap and intravitreal injections of vancomycin (1mg/0.1mL), ceftazidime (2.25mg/0.1mL), and dexamethasone (0.4mg/0.1mL). Cultures grew Staphylococcus epidermidis, resistant to moxifloxacin (MIC ≥8mg/L). The inflammation resolved over two months. Eight months later, the patient underwent uncomplicated cataract surgery in the left eye. Intracameral antibiotics were not used, however her systemic immunosuppressive therapy was held for several weeks perioperatively. One year after the initial surgeries, the patient had an uncorrected visual acuity of 20/20 in each eye. Conclusions and Importance S. epidermidis, the most common cause of postoperative endophthalmitis, is increasingly resistant to fluoroquinolones. Adequate concentrations of intracameral antibiotics need to be achieved in order to exceed minimal inhibitory concentration values of the targeted pathogen. Although intracameral moxifloxacin has been reported to decrease the rate of endophthalmitis after cataract surgery, it does not eliminate the risk.

Abstract
OBJECTIVES To investigate the diffusion of moxifloxacin through bandage contact lenses (BCLs) versus corneal collagen shields (CSs), the relative ability of BCLs and CSs to release moxifloxacin, and the potential of release of moxifloxacin from CSs in the clinical setting. METHODS Using an in vitro model, the diffusion of 5% moxifloxacin across BCLs and CSs was compared. Next, the amount of drug release from BCLs and CSs soaked in 0.5% moxifloxacin was measured. Finally, based on a clinical model, CSs were soaked in Vigamox (commercial moxifloxacin) and the total concentration released was detected. Collagen shields remained intact after 24 hr; therefore, enzymatic digestion and mechanical grinding of the CS were performed to determine whether further drug could be released. The concentration of moxifloxacin was measured using a spectrophotometer at set time points up to 24 hr. RESULTS In the diffusion assay, 35.7±10.5% diffused through the BCLs and 36.2±11.8% diffused through the CSs (P=0.77). The absorption assay demonstrated at 120 min, a total of 33.3±6.77 μg/mL was released from BCLs compared with 45.8±5.2 μg/mL from the CSs (P=0.0008). In vitro experiments to simulate clinical application of Vigamox-soaked CS found the concentration of moxifloxacin released of 127.7±7.25 μg/mL in 2 mL of phosphate-buffered saline over 24 hr. CONCLUSIONS Moxifloxacin diffuses through BCLs and CSs at similar rates; however, CSs have greater capacity to absorb and release moxifloxacin compared with BCLs. Vigamox-soaked CSs released 250 μg of moxifloxacin and may be a useful method to prevent endophthalmitis.

Abstract
PURPOSE To review current and past practices of intracameral antibiotic administration for infection prophylaxis in cataract surgery; to review the benefits and liabilities of available prophylactic drugs, dosage determination, and administration protocols; and to devise an optimum dose and administration protocol for intracameral moxifloxacin. SETTING Humber River Hospital and the University of Toronto, Toronto, Ontario, Canada. DESIGN Retrospective evaluation of treatment modality. METHODS This study consisted of a detailed review of the history, drugs, and methods of intracameral prophylaxis and microbiological and pharmacodynamics analysis of options. A review of potential drug sources and doses was performed and 1 drug, dose, and administration protocol was selected. The current method's adoption reasons are described followed by the authors' experience. RESULTS A single infection in 3430 cases occurred with a moxifloxacin-resistant strain of Staphylococcus epidermidis when moxifloxacin 100 mcg in 0.1 mL was used. Increasing the dose and changing the administration technique resulted in no infections in 4601 cases and no detrimental side effects or complications. CONCLUSION Intracameral moxifloxacin prepared by dilution of 3 cc moxifloxacin 0.5% (Vigamox) with 7 cc balanced salt solution and with the administration of 0.3 to 0.4 cc (450 to 600 mcg.) as the final step in cataract surgery via the side port after the main incision has been sealed and hydrated showed advantages over alternative intracameral antibiotic prophylactic methods, with minimum risk.

Abstract
Fluoroquinolones are synthetic antibacterial agents that stabilize the ternary complex of prokaryotic topoisomerase II enzymes (gyrase and Topo IV), leading to extensive DNA fragmentation and bacteria death. Despite the similar structural folds within the critical regions of prokaryotic and eukaryotic topoisomerases, clinically relevant fluoroquinolones display a remarkable selectivity for prokaryotic topoisomerase II, with excellent safety records in humans. Typical agents that target human topoisomerases (such as etoposide, doxorubicin and mitoxantrone) are associated with significant toxicities and secondary malignancies, whereas clinically relevant fluoroquinolones are not known to exhibit such propensities. Although many fluoroquinolones have been shown to display topoisomerase-independent antiproliferative effects against various human cancer cells, those that are significantly active against eukaryotic topoisomerase show the same DNA damaging properties as other topoisomerase poisons. Empirical models also show that fluoroquinolones mediate some unique immunomodulatory activities of suppressing pro-inflammatory cytokines and super-inducing interleukin-2. This article reviews the extended roles of fluoroquinolones and their prospects as lead for the unmet needs of "small and safe" multimodal-targeting drug scaffolds.

Abstract
Intraocular lenses (IOLs) present an alternative for extended, local drug delivery in the prevention of post-operative acute endophthalmitis. In the present work, we modified the surface of a hydrophilic acrylic material, used for manufacturing of IOLs, through plasma-assisted grafting copolymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS) or [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA), with the aim of achieving a controlled and effective drug release. The material was loaded with moxifloxacin (MFX), a commonly used antibiotic for endophthalmitis prevention. The characterization of the modified material showed that relevant properties, like swelling capacity, wettability, refractive index and transmittance, were not affected by the surface modification. Concerning the drug release profiles, the most promising result was obtained when AMPS grafting was done in the presence of MFX. This modification led to a higher amount of drug being released for a longer period of time, which is a requirement for the prevention of endophthalmitis. The material was found to be non-cytotoxic for rabbit corneal endothelial cells. In a second step, prototype IOLs were modified with AMPS and loaded with MFX as previously and, after sterilization and storage (30days), they were tested under dynamic conditions, in a microfluidic cell with volume and renovation rate similar to the eye aqueous humour. MFX solutions collected in this assay were tested against Staphylococcus aureus and Staphylococcus epidermidis and the released antibiotic proved to be effective against both bacteria until the 12th day of release.

Abstract
PURPOSE To compare the postoperative endophthalmitis rate before and after initiation of intracameral (IC) moxifloxacin prophylaxis for both phacoemulsification and sutureless, manual small-incision cataract surgery (M-SICS), as well as in patients with posterior capsular rupture (PCR). DESIGN Retrospective, clinical registry. PARTICIPANTS All cataract surgeries (617 453) performed during the 29-month period from January 2014 to May 2016 at the 10 regional Aravind eye hospitals were included. METHODS The electronic health record data for all study eyes were analyzed. Endophthalmitis rates before and after moxifloxaxin were statistically compared for all eyes and separately for both phacoemulsification and M-SICS, and for the eyes complicated by PCR. MAIN OUTCOME MEASURES The postoperative endophthalmitis rates before and after initiation of IC moxifloxacin prophylaxis. RESULTS Overall, 302 815 eyes did not receive IC moxifloxacin and 314 638 eyes did, and there was a significant decline in the endophthalmitis rate, from 0.07% (214/302 815) to 0.02% (64/314 638) (P < 0.001), with moxifloxacin. For the 194 252 phacoemulsification eyes, the endophthalmitis rate was 0.07% (75/104 894) without IC moxifloxacin prophylaxis, compared with 0.01% (11/89 358) with moxifloxacin (P < 0.001). For the 414 657 M-SICS eyes, the endophthalmitis rate was 0.07% (135/192 149) without IC moxifloxacin prophylaxis, compared with 0.02% (52/222 508) with moxifloxacin (P < 0.001). Approximately half of the 8479 eyes that had PCR received IC moxifloxacin, and half did not. Without IC moxifloxacin, PCR increased the endophthalmitis rate nearly 7-fold to 0.48% (20/4186); IC moxifloxacin reduced the endophthalmitis rate with PCR to 0.21% (9/4293) (P = 0.034). No adverse events were due to IC moxifloxacin. CONCLUSIONS Routine IC moxifloxacin prophylaxis reduced the overall endophthalmitis rate by 3.5-fold (3-fold for M-SICS and nearly 6-fold for phacoemulsification). There was also a statistical benefit for eyes complicated by PCR, and IC antibiotic prophylaxis should be strongly considered for this high-risk population. These conclusions are strengthened by the high volume of cases analyzed at a single hospital network over a comparatively short time frame. Considering the association of hemorrhagic occlusive retinal vasculitis with vancomycin and the commercial unavailability of IC cefuroxime in many countries, moxifloxacin appears to be an effective option for surgeons electing IC antibiotic prophylaxis.

Abstract
Levofloxacin is one of the Fluroquinoline antibiotic groups, which affect on controlling infections, especially in reproductive organs. It has therapeutic use in numerous countries, but little information exists on the effects of Levofloxacin on spermatogenesis when it is used for infectious treatment. The current study was designed to determine whether Levofloxacin influences testis tissue and spermatogenesis in rats. In this survey 50 male Wistar rats 6-8 weeks (250 ± 10 g) were used: normal salin as sham and control groups and 3 treatment groups (0.03, 0.06 and 0.08 mg Levofloxacin\kg body weight) during 60 days. The experimental groups were daily gavages. After 60 days, they were anesthetized with ether and testes were taken for histopathology studies, sperm parameters evaluation and several hormone concentrations. Although testosterone concentration was not affected by Levofloxacin levels, follicle stimulating hormone (FSH) and luteinizing hormone (LH) concentration significantly increased by Levofloxacin consumption in 0.03 and 0.06 mg Levofloxacin\kg body weight groups (P<0.01). Moreover, sperm concentration decreased linearly as Levofloxacin was increased (200, 192, 170, 128 and 75×10(6) sperm for control, sham, 0.03, 0.06 and 0.08 mg Levofloxacin\kg body weight, respectively, P<0.05). Testis tissue cuts in experimental group when the amount dosage of Levofloxacin increased cells solidarity to the primary and secondary spermatogonia. Adding Levofloxacin linearly reduced spermatocyte cells and amount of all cells in semenifer pipes tube (P<0.05). Levofloxacin as an antibiotic has histopathology effects on the spermatocyte cells, especially in high dose. Therefore, it might reduce fertility in male that requires further studies.

Abstract
PURPOSE To compare the anti-adhesive effect of cefuroxime and moxifloxacin on the primary attachment phase of Staphylococcus epidermidis on hydrophobic acrylic intraocular lenses (IOLs). METHODS Forty hydrophobic acrylic IOLs were used. Two groups of IOLs were soaked in a moxifloxacin (Mox-T1: 0.5 mg/0.1 ml) or a cefuroxime (Cef-T1: cefuroxime 1 mg/0.1 ml) solution before incubation in a S. epidermidis bacterial suspension. Two other groups were incubated in the bacterial suspension before antibiotics (Cef-T2 and Mox-T2) were added. The control group (Ctrl) consisted of IOLs incubated in the bacterial suspension. After incubation, IOLs were sonicated and vortexed. The resultant suspension was spread over a nutritive agar plate. Bacterial colonies were counted after 24 hr of incubation. RESULTS Mean number of colony-forming units per IOL was Cef-T1: 184 × 10(3) (SE: 5.24; SD: 28.21), Cef-T2: 117 × 10(3) (SE: 5.74; SD: 30.37), Mox-T1: 1.27 × 10(3) (SE: 0.12; SD: 0.61), Mox-T2: 25 × 10(3) (SE:1.98; SD: 9.72) and Ctrl: 361 × 10(3) (SE: 26.9; SD: 107.6). The number of adhering bacteria did not vary whether cefuroxime was added before or after IOL incubation in the bacterial suspension (p = 0.132). Moxifloxacin was more effective in reducing the number of adhering bacteria when used before IOL incubation (p < 0.001). Overall for T1 and T2, moxifloxacin was more effective than cefuroxime in reducing bacterial adhesion on IOLs (p < 0.001). CONCLUSION Moxifloxacin and cefuroxime significantly reduced S. epidermidis adhesion on hydrophobic acrylic IOLs. The anti-adhesive effect was superior with moxifloxacin.

Abstract
Endophthalmitis remains a rare but important cause of visual loss. Prophylaxis strategies are important to reduce rates of endophthalmitis after cataract surgery, intravitreal injection, and other procedures. There is substantial variability between the US and the rest of the world. During cataract surgery, intracameral antibiotics are commonly used in many nations, especially in Europe, but are less commonly used in the US. A randomized clinical trial from the European Society of Cataract and Refractive Surgeons reported an approximately fivefold reduction in endophthalmitis rates associated with intracameral cefuroxime but these results are controversial. There are no randomized clinical trials regarding endophthalmitis associated with intravitreal injection. Topical antibiotics are commonly used in many nations, but are less commonly used in the US. At this time, there is no global consensus and it appears unlikely that additional major clinical trials will conclusively define the optimal endophthalmitis prophylaxis techniques.

Abstract
The objective of this study is to evaluate the safety of undiluted 0.5 % intracameral moxifloxacin for postoperative endophthalmitis prophylaxis in cataract surgery patients without the use of additional postoperative topical antibiotics. All phacoemulsification cataract surgeries performed by a single surgeon (B.A.) at the John A. Moran Eye Center from June 2012 to May 2015 were reviewed retrospectively. From June 2012 to April 2014, patients were given topical 0.5 % moxifloxacin postoperatively. From May 2014 to May 2015, all patients were given moxifloxacin intracamerally with no antibiotics postoperatively. The follow-up period was 1 month after surgery. Preoperative visual acuity and postoperative visual acuity, corneal edema, and anterior chamber reaction were recorded and compared between the two groups. 384 cataract surgeries were performed during the study period. None of the 384 eyes in the study developed endophthalmitis. Of those 384 eyes, 222 were included in the study for analysis based on the inclusion and exclusion criteria. 131 were part of the topical antibiotic group and 91 were part of the intracameral group. The differences in uncorrected visual acuity at 1 day postoperatively (p = 0.595) and best corrected visual acuity at 1 month postoperatively (p = 0.099) were not statistically significant. Differences in corneal edema (p = 0.370) and anterior chamber reaction (p = 0.069) at 1 day postoperatively and corneal edema (p = 0.512) and anterior chamber reaction (p = 0.512) at 1 month postoperatively were also not statistically significant. Undiluted 0.5 % moxifloxacin can be safely injected intracamerally following cataract surgery without additional postoperative antibiotic prophylaxis to prevent endophthalmitis without adverse effects on patient outcomes.

Abstract
PURPOSE To compare the rate of postoperative endophthalmitis before and after initiation of intracameral (IC) moxifloxacin for endophthalmitis prophylaxis in patients undergoing cataract surgery. DESIGN Retrospective, clinical registry. PARTICIPANTS All charity and private patients (116 714 eyes) who underwent cataract surgery between February 15, 2014, and April 15, 2015, at the Madurai Aravind Eye Hospital were included. Group 1 consisted of 37 777 eyes of charity patients who did not receive IC moxifloxacin, group 2 consisted of 38 160 eyes of charity patients who received IC moxifloxacin prophylaxis, and group 3 consisted of 40 777 eyes of private patients who did not receive IC moxifloxacin. METHODS The electronic health record data for each of the 3 groups were analyzed, and the postoperative endophthalmitis rates were statistically compared. The cost of endophthalmitis treatment (groups 1 and 2) and the cost of IC moxifloxacin prophylaxis (group 2) were calculated. MAIN OUTCOME MEASURES Postoperative endophthalmitis rate before and after initiation of IC moxifloxacin endophthalmitis treatment cost. RESULTS Manual, sutureless, small incision cataract surgery (M-SICS) accounted for approximately all of the 75 937 cataract surgeries in the charity population (97%), but only a minority of the 40 777 private surgeries (21% M-SICS; 79% phacoemulsification). Thirty eyes in group 1 (0.08%) and 6 eyes in group 2 (0.02%) were diagnosed with postoperative endophthalmitis (P < 0.0001). The group 3 endophthalmitis rate was 0.07% (29 eyes), which was also higher than the second group's rate (P < 0.0001). There were no adverse events attributed to IC moxifloxacin in group 2. The total cost of treating the 30 patients with endophthalmitis in group 1 was virtually identical to the total combined cost in group 2 of routine IC moxifloxacin prophylaxis and treatment of the 6 endophthalmitis cases. CONCLUSIONS Routine IC moxifloxacin prophylaxis achieved a highly significant, 4-fold reduction in postoperative endophthalmitis in patients undergoing M-SICS. Compared with previous studies, having such a high volume of patients undergoing surgery during a relatively short 14-month time period strengthens the conclusion. This study provides further evidence that moxifloxacin is an effective IC prophylactic antibiotic and suggests that IC antibiotics should be considered for M-SICS and phacoemulsification.

Abstract
OBJECTIVE To study anterior eye segment toxicity of variously diluted brand name and generic antibiotic and antifungal drugs, including domestically produced generics (Moxifloxacin, asketin cefuroxime, amikacin, gentamicin, Diflucan, and amphotericin B), experimentally injected into the anterior chamber. MATERIAL AND METHODS A total of 13 Chinchilla rabbits were included in the experiment. Group 1 (6 rabbits) received sterile intracameral injections of 0.2 ml antibiotics and antifungals in concentrations suitable for intravenous administration (Moxifloxacin 1.6 mg/ml, Diflucan 2 mg/ml, and the following generics: asketin cefuroxime 125 mg/ml, amikacin 50 mg/ml, gentamicin 40 mg/ml, amphotericin B 50 mg/m). BSS was injected into the fellow eye for control. Group 2 (7 rabbits) also received sterile intracameral injections of 0.2 ml antibiotics and antifungals, which were the same as for group 1 but highly diluted (Moxifloxacin 150 μg/ml and 500 μg/ml, Diflucan 10 μg/ml, asketin cefuroxime 1 mg/ml, gentamicin 200 μg/ml, amikacin 400 μg/ml, amphotericin B 10 μg/ml). RESULTS There were no toxic effects in group 1 after BSS and Moxifloxacin 1.6 mg/ml injections into the anterior chamber. However, high concentrations of other antibiotic and antifungal drugs were associated with changes in the corneal endothelium of various severity (from cytoplasmic swelling of the endothelial cells to their complete desquamation), as well as fibrin exudation in the posterior chamber. In group 2 neither of injected drugs caused toxic, allergic, or inflammatory reactions according to histopathological examination. CONCLUSION The experiment proved safety of the intracameral route of administration for highly diluted medications from the list and also demonstrated the absence of toxic reaction after intracameral injection of Moxifloxacin 1.6 mg/ml.

Abstract
Purpose To elucidate Japanese trends for perioperative disinfection and antibiotic selection during cataract surgeries. Methods Perioperative iodine use and antibiotic prophylaxis for cataract surgery were surveyed in eight regions in Japan by mail or through interviews from February 1 to March 1, 2014. Results We surveyed 572 surgeons, of whom 386 (67%) responded. Most of the surgeons (94%) used iodine compounds before surgery for periocular skin disinfection (povidone–iodine [PI]: 79%; polyvinyl alcohol-iodine [PAI]: 15%) or conjunctival disinfection (85%; PI: 36%; PAI: 49%). Preoperative conjunctival iodine was primarily used as an eye wash (irrigation: 95%) and less often as an eye drop (5%). It was determined that 31% of surgeons waited 30 seconds or more between periocular disinfection and conjunctival disinfection. During surgery, 14% of surgeons used iodine several times, including immediately before intraocular lens insertion, and 7% used the Shimada technique (repeated iodine irrigation). Preoperative antibiotic eye drops were used by 99% of surgeons, and antibiotics were added to the irrigation bottle by 22%. The surgeons reported use of subconjunctival antibiotic injections (23%), antibiotic ointments (79%), and intracameral antibiotics (7%: 22 moxifloxacin; 6 levofloxacin). All surgeons prescribed postoperative eye drops, with 10% initiating the drops on the day of surgery. Conclusion Iodine compounds are commonly used preoperatively, but few institutions use iodine compounds intraoperatively, particularly with repeated application. The selection of antibiotic administration and disinfection technique has to be at the surgeon’s discretion. However, intracameral antibiotic and intraoperative iodine compound use are techniques that should be widely recognized.

Abstract
PURPOSE To evaluate and compare the toxic effects of moxifloxacin, cefuroxime, and levofloxacin on human corneal endothelial cells in vitro and determine the safe intracameral concentrations for them. SETTING Tottori University, Tottori, Japan. DESIGN Experimental study. METHODS Human corneal endothelial cells in culture were exposed to moxifloxacin, cefuroxime, and levofloxacin at concentrations up to 2000 μg/mL. Evaluation of membrane damage was determined by ethidium homodimer-1 uptake and cell viability, by intrinsic esterase activity. The inhibitory effects of the 3 antibiotics on the constitutive secretion of interleukin-6 (IL-6) by human corneal endothelial cells were determined by enzyme-linked immunosorbent assay. RESULTS The acute effects (6 hour) of the 3 antibiotics on membrane damage and cell death were dose-dependent for moxifloxacin and levofloxacin (≥ 500 μg/mL). For cefuroxime, membrane damage was not observed at 6 hours and only slight damage was detected at 24 hours at concentrations higher than 500 μg/mL. The half maximum inhibitory concentrations on cell viability of moxifloxacin, levofloxacin, and cefuroxime were 487 μg/mL, 578 μg/mL, and 1600 μg/mL, respectively. The inhibitory effects of the 3 antibiotics on the constitutive secretion of IL-6 were observed at 15.6 μg/mL or higher, indicating the antibiotics can impair the secretion of the protective cytokine even at low concentrations. CONCLUSIONS Moxifloxacin at more than 500 μg/mL caused damage to the cell membranes of corneal endothelial cells; even higher concentrations decreased cell viability. Considering the lower minimum inhibitory concentration for inhibiting 90% growth by moxifloxacin, intracameral moxifloxacin at 500 μg/mL or less is recommended for prophylactic use.

Abstract
PURPOSE To assess the safety of intracameral injection of moxifloxacin (MFLX) using the total replacement technique [bag and chamber (BC) flushing]. METHODS The anterior chamber including the area behind the intraocular lens was irrigated and replaced using BC flushing. In Group A, 36 patients received balanced salt solution irrigation in the right eye and intracameral MFLX (150 μg/mL: 33-fold dilution of 0.5% eye drops) in the left eye. In Group B, 33 patients received intracameral MFLX in the right (500 μg/mL: 10-fold dilution) and left eyes (150 μg/mL: 33-fold dilution). Visual acuity, intraocular pressure, corneal endothelial cell density, corneal thickness, and foveal thickness were recorded before and up to 3 months after surgery. RESULTS In either group, there were no statistically significant differences between the right and left eyes with respect to visual acuity, intraocular pressure, corneal endothelial cell count, and foveal thickness before and at 3 months after surgery. There was no difference in corneal thickness before and at 3 months after surgery. In patients who received 500 μg/mL MFLX during surgery, central corneal thickness at 1 week after surgery was significantly reduced. CONCLUSIONS In the present study, there was no adverse effect associated with intracameral injection of 150-500 μg/mL MFLX. Moreover, our results supported the safety of BC flushing. Thus, BC flushing, which can irrigate the inside of the capsular bag and attain stable antibiotic concentrations, appears to be a favorable technique for intracameral injection of MFLX.

Abstract
Postoperative endophthalmitis is one of the most serious potential complications of ocular lens surgery. Its incidence can be reduced by means of antibiotic prophylaxis. Although the prophylactic use of intracameral cefuroxime has been extended, other drugs, such as moxifloxacin, have arisen as alternatives. We performed a systematic literature review on the effectiveness and efficiency of intracameral cefuroxime and moxifloxacin for the prophylaxis of postoperative endophthalmitis after cataract surgery. Several bibliographic databases were searched up to October 2010 and were updated up to January 2013. Outcomes were the onset of endophthalmitis after surgery and the cost-effectiveness ratio of using both antibiotic prophylaxis alternatives. The following were included: a clinical trial reported in two papers, six observational studies, and an economic evaluation. All studies assessed cefuroxime compared with another antibiotic prophylaxis or no prophylaxis. The only randomized controlled trial performed by the European Society of Cataract and Refractive Surgery found that intracameral cefuroxime is significantly more effective than not using prophylaxis or the use of a topical antibiotic. The observational studies support these results. The economic evaluation compared different prophylaxis regimens and concluded that intracameral cefuroxime showed the best cost-effectiveness ratio. Both the observational studies and the economic evaluation have methodological limits that reduce their validity. This review confirmed that cefuroxime can prevent endophthalmitis after cataract surgery. Further randomized controlled trials, with large sample sizes, are required to compare different antibiotic prophylaxis regimens.

Abstract
OBJECTIVE In this experimental study, we investigated the possible effects of intracameral moxifloxacin on oxidative stress parameters and endothelial cell morphology in corneal tissue. METHODS In total, 30 rats were randomly assigned to three groups of 10 rats: the sham group (Group 1, n = 10); the control group (Group 2), where balanced salt solution (BSS) was administered at a dose of 0.01 cc (n = 10); and the treatment group (Group 3), where moxifloxacin was administered at a dose of 0.05 mg/0.01 cc (n = 10). Total antioxidant status (TAS) and total oxidant status (TOS) in corneal tissue and blood samples were measured and the oxidative stress index (OSI) was calculated. Also, corneal tissue histopathology was evaluated with caspase-3 and caspase-8 staining. Apoptotic activity was also evaluated. RESULTS In blood samples, TAS, TOS, and OSI levels were not statistically significantly different (all p > 0.05). Compared with the sham and control groups, TOS and OSI levels in cornea tissue were significantly different in the moxifloxacin group (all p < 0.05). However, compared with the control group, no statistically significant difference was found in the sham group (all p > 0.05). Compared with the sham and control groups, apoptotic activity was higher in the moxifloxacin group, in both immunohistochemical staining for caspase-3 and caspase-8. CONCLUSIONS Intracameral moxifloxacin injection seems to be safe systemically, but it may have toxic effects on corneal tissues, as suggested by oxidative stress parameters and a histopathological evaluation.

Abstract
Data on practice patterns for prophylaxis against infectious postoperative endophthalmitis (IPOE) during cataract surgery in 9 European countries were searched in national registers and reviews of published surveys. Summary reports assessed each nation's IPOE rates, nonantibiotic prophylactic routines, topical and intracameral antibiotic use, and coherence to the European Society of Cataract & Refractive Surgeons (ESCRS) 2007 guidelines. Although the reliability and completeness of available data vary between countries, the results show that IPOE rates differ significantly. Asepsis routines with povidone-iodine and postoperative topical antibiotics are generally adopted. Use of preoperative and perioperative topical antibiotics as well as intracameral cefuroxime varies widely between and within countries. Five years after publication of the ESCRS guidelines, there is no consensus on intracameral cefuroxime use. Major obstacles include legal barriers or persisting controversy about the scientific rationale for systematic intracameral cefuroxime use in some countries and, until recently, lack of a commercially available preparation.

Abstract
A retrospective case-control study of patients who had undergone cataract extraction at a Spanish hospital over a 13-year period was conducted to identify the risk factors for developing post-operative endophthalmitis (POE). During the study period, the type of antibiotic prophylaxis was changed from subconjunctival gentamicin to the addition of both vancomycin and gentamicin to the irrigating solution. The overall incidence of POE was 0·19% (35 cases/18 287 operations). For the period prior to the change in antibiotic prophylaxis, the incidence rate of POE was 3·4 cases/1000 operations while in the latter period the incidence rate decreased to 0·34 cases/1000 operations. All patients who presented a virulent microorganism had a final visual acuity worse than 20/200. The only significant risk factor identified was the type of prophylaxis used (odds ratio 1·97, 95% confidence interval 0·94-4·14, P = 0·07). There were no significant differences between cases and controls although choice of surgeon approached significance.

Abstract
OBJECTIVE This study aims to assess whether changes in antibiotic prophylaxis used in cataract surgery in the La Mancha Centro General Hospital, Spain, were associated with a reduced incidence of postoperative endophthalmitis (POE). METHODS The hospital employed two different antibiotic prophylaxis regimens during two clearly differentiated periods. In the first period (January 2000 to April 2003), subconjunctival injections of gentamicin were used while in the second (May 2003 to December 2008), vancomycin and gentamicin were added to the irrigating solution. During both periods, povidone iodine was used at the site of surgery and aminoglycoside eye drops were administered postoperatively. A Poisson regression model was used to evaluate the relationship between the incidence rate of endophthalmitis and variables such as time trends, seasonality, and change in antibiotic prophylaxis regimen. RESULTS During the period between 2000 and 2008, 26 cases of POE were detected after 14,285 operations for an incidence rate (IR) of 1.8 cases per 1000 procedures (95% confidence interval 1.2-2.7 cases out of 1000 procedures). In the period prior to the change in prophylaxis, 23 cases were detected (IR 4.5 cases/1000 procedures) while only three cases were observed in the period after the change (IR 0.3 cases/1000 procedures). A total of 84% of the microorganisms isolated were gram-positive, and all were sensitive to vancomycin. CONCLUSIONS The change in antibiotic prophylaxis regimen for cataract surgery was associated with a relevant and significant decrease in the incidence of POE.

Abstract
We conducted a cohort study to evaluate post-cataract surgery endophthalmitis rates in relation to prophylactic intracameral moxifloxacin administration. A total of 2332 patients (2674 eyes) who underwent phacoemulsification by a single surgeon from January 2007 through December 2012 were included in the study. A total of 1056 eyes did not receive intracameral prophylactic moxifloxacin and the antibiotic was injected in 1618 eyes. The incidence of presumed postoperative endophthalmitis in the 2 groups was calculated. The rate of presumed infectious endophthalmitis after cataract surgery between January 2007 and June 2009 (without intracameral moxifloxacin) was 0.094%. The rate in the second period, from July 2009 to December 2012 (with prophylactic intracameral moxifloxacin), was 0%. In our patients, a decline in the incidence of presumed infectious postoperative endophthalmitis appeared to be associated with the application of intracameral moxifloxacin.

Abstract
UNLABELLED Abstract Purpose: To evaluate the antiproliferative and cytotoxic properties of moxifloxacin on cultured rat retinal ganglion cells (RGC5). MATERIALS AND METHODS Rat retinal ganglion cells were exposed to various concentration of moxifloxacin (5-1500 μg/mL). For antiproliferative properties, the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) test was performed. Cellular cytotoxicity was assessed by using the Live/Dead viability/cytotoxicity assay and analyzed by fluorescence microscopy after 24 and 72 h of incubation, respectively. RESULTS Neither cytotoxic nor antiproliferative effect of moxifloxacin was observed below 50 μg/mL on RGC5 cells after 24 and 72 h of incubation. At higher concentrations of moxifloxacin (150 μg/mL, 500 μg/mL, and 1500 μg/mL (p < 0.001)) the number of viable cells and the proliferation rate of RGC5 were significantly reduced. CONCLUSIONS These results suggest a dose-dependent cytotoxic and antiproliferative effect of moxifloxacin on RGC5. Therefore, intracameral application of moxifloxacin should be used cautiously in patients with increased risk of retinal ganglion cells damage, particularly in glaucoma patients.

Abstract
PURPOSE To compare the intraocular penetration of 4 fluoroquinolone eye drops after topical instillation into rabbit eyes. METHODS The tested drugs were levofloxacin 1.5% (LVFX), gatifloxacin 0.3%, moxifloxacin 0.5% (MFLX), and besifloxacin 0.6% (BFLX). Forty-eight New Zealand white rabbits were randomly assigned into 2 groups. For group 1 (40 rabbits, 80 eyes), single instillation was performed, and tissue samples were acquired after 0.5, 1, 2, 4, and 6 hours. For group 2 (8 rabbits, 16 eyes), repeated instillation was performed (4 times, every 15 minutes), and tissues were acquired 1 hour after the fourth instillation. The drug concentrations in ocular tissues (cornea, aqueous, conjunctiva, and trisected vitreous) were analyzed with high-performance liquid chromatography. RESULTS The AUC 0-6 h (area under the curve, in microgram.hour/gram) in group 1 and the mean concentration (in micrograms/gram) in group 2 for LVFX, gatifloxacin 0.3%, MFLX, and BFLX, respectively, were 22.97, 6.44, 13.54, and 3.29 and 22.60, 6.99, 13.69, and 1.91 in cornea; 5.66, 1.43, 3.38, and 0.42 and 5.52, 1.29, 2.47, and 0.19 in aqueous humor; 2.33, 0.91, 2.17, and 9.83 and 4.51, 0.78, 1.48, and 2.09 in bulbar conjunctiva; 0.243, 0.051, 0.134, and 0.018 and 0.182, 0.055, 0.122, and 0.015 in anterior vitreous; none of the drugs achieved enough concentration in equatorial and posterior vitreous. Repeated instillation resulted in approximately 2.1 times greater penetration than single instillation. CONCLUSIONS LVFX and MFLX demonstrated good intraocular penetration particularly in cornea, aqueous humor, and anterior vitreous, and they may be considered the penetrative fluoroquinolones. BFLX showed high concentration in bulbar conjunctiva and may be considered the retentive fluoroquinolone.
