Abstract
Purpose: To investigate the safety of applying therapeutic contact lenses and eye drops after cataract surgery.Methods: Immediately after cataract surgery, 947 eyes (group 1) used therapeutic contact lenses and eye drops and 914 (group 2) applied antibiotic ointment and wore a gauze eye patch for the first postoperative day. Clinical outcomes including best corrected visual acuity (BCVA), IOP, degree of anterior chamber inflammation, wound leakage, and postoperative endophthalmitis were compared in the two groups 1 day, 1 week, and 1 month after surgery.Results: There were no significant differences in the mean pre- and postoperative BCVA and IOP at 1 day, 1 week, and 1 month between groups 1 and 2. There was no difference in anterior chamber inflammation between the two groups at 1 day (p = 0.302), 1 week (p = 0.437), or 1 month (p = 0.960) after surgery. On the first postoperative day, 10 eyes in group 1 and nine eyes in group 2 had wound leakage (p = 1.000). There was no endophthalmitis in either group.Conclusions: The risk of postoperative complications in group 1 was not higher than in group 2. Therefore, wearing therapeutic contact lenses and using eye drops is a relatively safe management method after cataract surgery.

[PMID: 34863675 DOI: 10.1016/j.jcjo.2021.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 10/07/2021] [Accepted: 11/04/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND There is a high variability in the use of postoperative eye protection among ophthalmologists. Postoperative eye protection treatment modalities include an eye shield, an eye patch, an ocular bandage, and instant vision. The aim of this study was to review and compare the evidence on the various options for eye protection. METHODS A systematic literature search was conducted, and original comparative articles that reported on subjective symptoms (e.g., foreign-body sensation, photophobia, tearing, and pain) and postoperative outcomes (e.g., tear film breakup time, best-corrected visual acuity, etc.) after usage of an eye protection method were included. RESULTS Overall, 598 eyes across 8 articles were included. Included studies investigated ocular bandages (n = 6), eye patches (n = 4), instant vision (n = 2), and eye shields (n = 1) postoperatively. In 5 studies, patients receiving ocular bandages self-reported symptoms, including pain (n = 3), foreign-body sensation (n = 4), photophobia (n = 3), and tearing (n = 3), at a reduced or equivalent rate compared with other treatment modalities. With the ocular bandage, 3 studies reported increased tear film breakup time, and 1 study reported improvements in corneal wound healing compared with a control group. Two studies reported reduced tear film breakup time for the eye patch relative to the ocular bandage, and another study reported reduced tear film breakup time for instant vision compared with the eye patch. CONCLUSIONS Patient-reported symptoms are acutely reduced for patients receiving an ocular bandage relative to instant vision following cataract surgery. Patients prefer receiving some form of postoperative protection as opposed to instant vision.

Comparative Evaluation of Bandage Contact Lenses and Eye Patching after Bilateral Cataract Surgery. J Ophthalmol 2021; 2021:2873543. [PMID: 34422403 PMCID: PMC8378946 DOI: 10.1155/2021/2873543] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Accepted: 08/05/2021] [Indexed: 11/18/2022] Open
Abstract
Purpose To comparatively evaluate the safety and satisfaction of bandage contact lens (BCL) and eye patching in patients after cataract surgery. Methods Sixteen (32 eyes) patients who planned to undergo bilateral cataract surgery were recruited. The two eyes of each patient were randomly divided into 2 groups. Group A and Group B were instructed to wear BCLs immediately at the end of the surgery until one week and eye patch immediately after surgery until one day, respectively. Visual analog scales of ten specific symptoms, Visual Function Index (VF-14) questionnaire, and best-corrected visual acuity (BCVA) were conducted on the first day before the surgery and Day 1 and Day 7 after surgery. Oculus keratography was conducted on the first day before surgery and on Day 7. Patient satisfaction was determined on Day 1. Moreover, bacterial species in the conjunctival sac, meibomian gland secretions, and BCLs were subsequently identified using 16S rRNA gene sequencing. Results The patient satisfaction scores of Group A were higher than Group B. Group A were more motivated to choose the same treatment and were more likely to recommend BCLs to others. No statistically significant differences were found in bacterial culture positivity between the groups. The differences in ocular signs and symptoms between the two groups were not statistically significant. There were no significant differences in the BCVA and VF-14 between the groups at any time point. Conclusions BCLs could be safely and effectively used in patients after cataract surgery.

Abstract
PURPOSE To evaluate the effect of postoperative eye patching after routine cataract surgery on corneal oedema and visual acuity on the first postoperative day. SETTING One public healthcare centre. DESIGN AND METHODS This randomized controlled trial included patients undergoing uneventful cataract surgery in one medical centre. Patients were randomized into two groups: the surgical eye was patched with a single dose of a local steroid and antibiotic for 24 hr in the first group, and a plastic shield was used in the second with local steroid and antibiotic drops. The eyes were examined preoperatively and on the first postoperative day. Examination included the following: best-corrected visual acuity (BCVA), full slit lamp examination, intraocular pressure (IOP), anterior chamber depth (ACD) and central corneal thickness (CCT) using the IOL Master 700 (Zeiss, Germany). Cumulative dissipated energy (CDE) and operation time were recorded for all cases. RESULTS One hundred eyes of 100 patients were included in the study. The postoperative increase in CCT 24 hr after surgery was 138 and 70 µm in the patched group as compared to the non-patched group, respectively (p = 0.001). Best-corrected visual acuity (BCVA) on the first postoperative day was 0.5 ± 0.45 LogMAR and 0.3 ± 0.3 LogMAR in the patched and non-patched group, respectively (p = 0.01). There was no difference in CDE (11.33 ± 9.2 and 10.22 ± 7.3; p = 0.94) between the two groups. CONCLUSIONS Eye patching after routine cataract surgery is associated with an increase in corneal oedema and slower visual recovery on the first postoperative day.

Abstract
PURPOSE Pain after an intravitreal injection (IVI) can last up to 7 days and negatively impacts the patient's experience, potentially reducing treatment compliance. We prospectively evaluated topical nepafenac 0.3% suspension and patching for the reduction of pain after IVI. DESIGN Randomized controlled trial. PARTICIPANTS Sixty patients receiving an IVI of bevacizumab, aflibercept, or triamcinolone acetonide in 1 eye. METHODS Participants were randomized equally to receive either a single drop of nepafenac 0.3%, a pressure patch for 2 hours, or a single drop of preservative-free artificial tears (control group). A single-blinded placebo-controlled design was used to mask the topical treatment used. Pain was assessed using the Numeric Pain Rating Scale that ranged from 0 to 10 (horizontal pain scale). Because pain scores were not normally distributed, statistical analysis was performed using a nonparametric randomization-based analysis of covariance. MAIN OUTCOME MEASURE Pain scores. RESULTS Fifty-six and 53 patients of the 60 patients enrolled completed the 6- and 24-hour follow-ups, respectively. Numeric Pain Rating Scale scores at 6 and 24 hours after IVI were lower in the nepafenac group (0.8±0.3 and 0.1±0.1, respectively; n = 18) and the patching group (1.3±0.4 and 0.4±0.2, respectively; n = 19) compared with the control group (2.5±0.6 and 0.9±0.4, respectively; n = 19). After controlling for age, gender, number of prior injections, and physician administering the injection, patients in the nepafenac group reported significantly lower pain scores than those in the control group at 6 hours (1.3±0.6 less; P = 0.047) and 24 hours (0.7±0.3 less; P = 0.047). Although the patching group reported lower pain scores than the control group, this was not statistically significant (6 hours, P = 0.24; 24 hours, P = 0.29). CONCLUSIONS Nepafenac 0.3% was effective as a single drop in reducing pain at 6 and 24 hours after IVI compared with placebo. Limited patching was associated with lower pain scores than placebo, but the difference was not statistically significant. Additional studies are needed to determine the most effective method to maximize the patient's experience after an IVI without sacrificing outcomes.

Bandage Lenses in the Postoperative Care for Cataract Surgery Patients: A Substitute for Eye Patch? J Ophthalmol 2018; 2018:1493967. [PMID: 29887990 PMCID: PMC5977021 DOI: 10.1155/2018/1493967] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2018] [Revised: 04/05/2018] [Accepted: 04/17/2018] [Indexed: 11/17/2022] Open
Abstract
Purpose To explore whether bandage lenses could be a safe and effective substitute for eye patch in the postoperative care for cataract surgery patients in terms of infection prevention, ocular impacts, and patient satisfaction. Methods Patients who underwent cataract surgery were randomly divided into the eye patch group (Group A) and the bandage lens group (Group B). Bacterial culture samples were collected perioperatively from different sites. Evaluations of anterior segment condition and patient satisfaction were conducted on the first day of postoperative follow-up. Results The positive rate of bacterial cultures in Group A was higher than that in Group B, but the difference was not statistically significant. Group B had significantly longer tear breakup time, higher tear meniscus height, and slightly better patient satisfaction than Group A. Conclusion Bandage lenses can be used as a safe and effective substitute for eye patch in the postoperative care for cataract surgery patients. The Clinical Study registration number is ChiCTR-IOC-17012167.

Abstract
Cataract surgery is the most common ophthalmological surgical procedure, and it is predicted that the number of surgeries will increase significantly in the future. However, little is known about the recovery after surgery. The first aim of this study was to evaluate the prevalence, severity and duration of pain and other ocular discomfort symptoms experienced after cataract surgery. The other objectives were to identify the factors associated with lower postoperative patient satisfaction and to measure the effect of cataract surgery on patients' health-related quality of life (HRQoL) and visual function in everyday life. The study design was a prospective follow-up study. The course of the recovery and the presence of ocular symptoms were evaluated by interviewing the patients via a questionnaire at 1 day, 1 week, 6 weeks and one year after surgery The visual functioning in everyday life was measured with Visual Functioning Index VF-7 and Catquest-9SF-questionnaires and furthermore the HRQoL was measured with the 15D-instrument before surgery and at 12 months after surgery. The patients returned the questionnaires by mail and were interviewed in the hospital on the day of the surgery. The same patients filled-in all the questionnaires. The patient reports were used to collect the data on medical history. A total of 303 patients were approached at Kuopio University Hospital in 2010-2011 and of these 196 patients were eligible and willing to participate, with postoperative data being available from 186 (95%) patients. A systematic review article was included in the study procedure and it revealed the wide range in the reported incidence of postoperative ocular pain. Some of the identified randomized controlled studies reported no or only minor pain whereas in some studies significant pain or pain lasting for several weeks has been described in more than 50% of the study patients. In the present study setting, pain was reported by 34% during the first postoperative hours and by approximately 10% of patients during the first six weeks after surgery. During the early recovery in the hospital, only a minority of the patients reporting pain were provided with pain medication. The ocular discomfort symptoms such as itchiness, burning, foreign-body sensation and tearing were common both before (54%) and after surgery (38-52%). These symptoms can also be described as painful symptoms and are often difficult to distinguish from ocular pain. The symptoms are also typical of ocular surface disease, and some patients may benefit from the postoperative administration of tear substitutes. The patients reporting postoperative ocular symptoms were less satisfied with the treatment outcome at 12 months after surgery (p = 0.001) compared to the patients who experienced no symptoms. Those patients reporting less disability in visual functioning before surgery were more satisfied than patients with more reported disability. The HRQoL improved significantly after cataract surgery (p = 0.002). However, when compared to an age-and gender-standardized control population, in cataract subjects the HRQoL remained slightly worse both before and at 12 months after surgery.

Abstract
Cataract extraction surgery is the most common surgical procedure, but knowledge of postoperative pain related to cataract surgery is sparse. In this systematic review, the incidence, prevalence, and management of pain after phacoemulsification surgery were identified using PubMed and Scopus. Selected studies were restricted to randomized controlled trials with interventions on postoperative inflammation and pain. Data from 105 articles were extracted and 21 studies met the final inclusion criteria. Most studies reported no or only mild postoperative pain, but some reported moderate and severe pain and pain lasting several weeks. The interventions consisted of drug therapy including topical nonsteroidal antiinflammatory drugs, corticosteroids, paracetamol, perioperative intraocular injections, eye pads used after surgery, and various surgical techniques. The reviewed literature indicates that cataract surgery is associated with significant postoperative pain in some patients, who should be provided with appropriate counseling and pain treatment.

Abstract
Purpose To evaluate postoperative pain and early recovery in cataract patients. Patients and methods A total of 201 patients who underwent elective first eye cataract extraction surgery were enrolled, and 196 were included in the final analysis. The study design was a single-center, prospective, follow-up study in a tertiary hospital in eastern Finland. Postoperative pain was evaluated with the Brief Pain Inventory at four time points: at baseline, and at 24 hours, 1 week, and 6 weeks postsurgery. Results Postoperative pain was relatively common during the first hours after surgery, as it was reported by 67 (34%) patients. After hospital discharge, the prevalence decreased; at 24 hours, 1 week, and 6 weeks, 18 (10%), 15 (9%) and 12 (7%) patients reported having ocular pain, respectively. Most patients with eye pain reported significant pain, with a score of ≥4 on a pain scale of 0–10, but few had taken analgesics for eye pain. Those who had used analgesics rated the analgesic efficacy of paracetamol and ibuprofen as good or excellent. Other ocular irritation symptoms were common after surgery; as a new postoperative symptom, foreign-body sensation was reported by 40 patients (22%), light sensitivity by 29 (16%), burning by 15 (8%), and itching by 15 (8%). Conclusion Moderate or severe postoperative pain was relatively common after cataract surgery. Thus, all patients undergoing cataract surgery should be provided appropriate counseling on pain and pain management after surgery.

Abstract
BACKGROUND Cataract surgery, the most frequently performed operative procedure worldwide, typically concludes with the implantation of an artificial intraocular lens (IOL) to correct aphakia (absence of the crystalline lens). METHOD Selective literature review including current regulations, guidelines and recommendations for cataract surgery. RESULTS The main symptom of cataract is loss of visual acuity, which usually progresses slowly. It can arise in one eye or both. There is a basic distinction between congenital and acquired cataracts. The probability of developing a cataract rises with age because of biochemical aging processes. The development of a cataract becomes highly likely from the sixth decade of life onward. CONCLUSIONS As no effective medications for cataract are available at present, its current standard treatment is the removal of the clouded lens. In industrialized countries, this is usually done with ultrasound (phacoemulsification), followed by the implantation of an IOL.
