Mönestam EI. Long-term results of cataract surgery in type 2 diabetics, a 20-year prospective longitudinal study. Acta Ophthalmol 2024; 102:58-67. [PMID: 37140144 DOI: 10.1111/aos.15684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 03/30/2023] [Accepted: 04/21/2023] [Indexed: 05/05/2023]
Abstract
PURPOSE To investigate the 20-year outcome, in best-corrected visual acuity (BCVA), and subjective visual function (VF-questionnaire, VF-14) after cataract surgery in type 2 diabetics, compared with non-diabetics. METHODS 109 type 2 diabetics and 698 non-diabetics, who had cataract surgery during 1 year at one institution, were included in this prospective, longitudinal, population-based cohort study. BCVA and VF-14 responses were recorded pre- and postoperatively, and every 5 years up to 20 years after surgery. Retinopathy was graded before surgery. RESULTS There was no significant difference between diabetics and non-diabetics, in change in BCVA from 10 years or more after surgery, p = 0.45, p = 0.44 and p = 0.83, at 10, 15 and 20 years, respectively, as well as in self-perceived visual function (VF-14) at any time after surgery, p = 0.72, p = 0.20 and p = 0.78, 10-20 years, respectively. At any follow-up, there was no significant difference in BCVA in relation to retinopathy level before surgery, p = 0.1 at 20 years. There was a trend from 10 years after surgery and onward that patients with no retinopathy at baseline lost fewer letters during the 20 years than diabetics with retinopathy. Patients with known type 2 diabetes at surgery had a significantly lower survival compared with the non-diabetics at each follow-up, p = 0.003. CONCLUSION In surviving diabetics, BCVA and subjective visual function were retained in most cases up to 20 years after cataract surgery. Cataract extraction is effective in causing a sustainable improvement in visual function also in type 2 diabetics. Knowledge of these long-term outcomes is essential when counselling diabetics for cataract surgery.

The correlation between peripheral complete blood count parameters and diabetic macular edema in proliferative diabetic retinopathy patients: a cross-sectional study. Front Endocrinol (Lausanne) 2023; 14:1190239. [PMID: 37538792 PMCID: PMC10395099 DOI: 10.3389/fendo.2023.1190239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 06/30/2023] [Indexed: 08/05/2023] Open
Abstract
Background Numerous studies have demonstrated that retinal chronic inflammation plays a critical role in the pathogenesis of diabetic macular edema (DME). However, studies about the association between peripheral complete blood count, an inexpensive and easily measurable laboratory index, and DME are limited. Research design and methods The current study was a hospital-based, cross-sectional study. The participants were inpatients with type 2 diabetes who underwent vitrectomy for PDR, and the contralateral eyes in these PDR patients meeting the criteria were included in the study. Central macular thickness (CMT) was measured automatically and the DME was characterized as CMT ≥ 300 μm. Results A total of 239 PDR participants were enrolled. The average age was 55.46 ± 10.08 years old, and the average CMT was 284.23 ± 122.09 μm. In the fully adjusted model, for CMT, the results revealed a significantly negative association between CMT and both white blood cell (WBC) count and neutrophil count (β = -11.95, 95% CI: -22.08, -1.82; p = 0.0218; β = -14.96, 95% CI: -28.02, -1.90; p = 0.0259, respectively); for DME, the results showed an inverse association between DME and WBC count, monocyte count, and eosinophil count (OR = 0.75, 95% CI: 0.59, 0.95; p = 0.0153; OR = 0.07, 95% CI: 0.00, 0.92; p = 0.0431; OR = 0.03, 95% CI: 0.00, 0.88; p = 0.0420, respectively). Conclusions In conclusion, our results suggest that WBC and its subtypes in circulation may play an important role in the pathogenesis of DME in PDR patients.

Abstract
Purpose Compare postoperative outcomes in cataract surgery between eyes with standard drop regimen versus dropless protocol by residents. Design Retrospective cohort study between April 1, 2018 and March 31, 2020. Methods The study was performed at Lyndon B. Johnson General Hospital in Houston, Harris County, Texas. A total of 547 eyes (234 dropless vs. 313 standard) with phacoemulsification cataract surgery and minimum of 1-month follow-up with best-corrected visual acuity (BCVA) were included. Dropless received 40 mg sub-Tenon's triamcinolone and intracameral moxifloxacin. Patients were followed at postoperative day 1 (POD1), week 1 (POW1), and month 1 (POM1). Postoperative rate of BCVA better than 20/40 (Good vision) and rate of complications were compared between groups. Results Good vision on POM1 in dropless (77.8%) was noninferior to standard (75.1%, p = 0.80). Complication rate in dropless (28.6%) was noninferior to standard (24.0%, p = 0.13). Intraocular pressure (IOP) elevation on POD1 ( p = 0.041) and anterior chamber (AC) cells on POW1 and POM1 ( p < 0.001) were more frequent in dropless. Mean spherical equivalent at POM1 was better in dropless (-0.37 D [±0.81 D]) compared with standard (-0.61D [±0.77 D], p = 0.001). Early posterior capsular opacification (early PCO) was more frequent in dropless ( p = 0.042). Conclusions Postoperative rate of BCVA better than 20/40 and rate of postoperative complications were noninferior, although dropless had higher rates of AC inflammation, IOP elevation, and early PCO.

Abstract
PURPOSE OF REVIEW To review most recent studies and clinical trials regarding pathogenesis, treatment, and prevention of inflammation after the cataract surgery. RECENT FINDINGS FLACS gave opportunity to evaluate inflammatory cytokines in the aqueous humour right after the laser procedure, which led to acknowledging the inflammation pathogenesis during the phacoemulsification. Although there is still a lack of evidence, which would prove the long-term benefit of NSAIDs, they are indicated and effective when risk factors for PCME are present. PREMED studies showed that combination of NSAID and steroids after the surgery for healthy subjects is cost-effective. The triamcinolone injection together with topical steroids and NSAIDs for diabetic patients after the cataract surgery was the most cost-effective in preventing PCME according to the PREMED. Dropless cataract surgery is another emerging topic: dexamethasone implants and suspensions look promising as we await more clinical trials with drug-loaded IOLs. SUMMARY Inflammation after the cataract surgery can be prevented, and these methods are one of the most essential topics with growing phacoemulsification rate. Topical NSAIDs are cost-effective not only for patients with risk factors for PCME but also for healthy subjects. New dropless techniques are being successfully introduced in the clinical practice.

Abstract
A cataract in the eye is a major cause of vision loss in diabetic patients, which occurs earlier and develops faster than non-diabetic patients, and often requires surgery for treatment. However, diabetic patients undergoing cataract surgery have a higher risk of intraoperative and postoperative complications than non-diabetic patients. For diabetic patients undergoing any surgery, careful perioperative assessment and management are required to reduce postoperative complications and improve surgical outcomes. Better understanding of their needs may guide perioperative practitioners to manage their care appropriately. This article presents recent evidence and guidance associated with the preoperative, intraoperative and postoperative management of diabetic patients undergoing cataract surgery and to inform perioperative practitioners of the challenges and potential complications to provide the best care and improve sight.

Abstract
PURPOSE To identify parameters that can predict the postoperative risk for progression of retinopathy to a vision-threatening stage after cataract surgery. This may optimize the timing of surgery and the postoperative follow-up strategy in diabetic patients. METHODS Multi-state survival analysis with death as competing risk was used to investigate how year of onset and age of onset of diabetes, gender, body mass index, HbA1c and blood pressure had affected the risk for developing diabetic macular oedema (DME) and proliferative diabetic retinopathy (PDR) among 2540 right eyes from 2797 diabetic patients operated for cataract on one or both eyes during 25 years until July 1. 2019. RESULTS Cataract surgery had been performed in 98.8% of patients reaching 90 years of age. The risk for developing both DME and PDR was increased by cataract surgery. The risk was highest during the first postoperative years and increased by pre-operative variability in HbA1c. The risk after more than 20 years postoperatively increased by increased cumulative HbA1c pre-operatively. The other studied risk factors contributed differently to the development of the two complications. CONCLUSIONS Decision models for the timing of cataract surgery in diabetic patients should consider that the risk for developing vision-threatening retinopathy depends on follow-up time. Differences in the risk profiles for developing DME and PDR after cataract surgery support that the two complications should be regarded as separate late complications.

Abstract
BACKGROUND Post-operatively, cataract surgery is associated with pseudophakic cystoid macular oedema (PCMO) causing vision disturbances. The presence of comorbidities may increase the incidence of PCMO post-cataract surgery. OBJECTIVE This observational study aimed to assess the incidence of PCMO in Australia (Illawarra region) and identify risk factors for developing PCMO. METHODS Retrospective analysis was performed on data from patients who underwent uncomplicated phacoemulsification and intraocular lens implantation between 1st March and June 30, 2016. Demographics, comorbidities, central subfield thickness (CST), visual acuity, and intraocular pressure (IOP) were collected preoperatively, day 1, and weeks 2, 4, and 6 post-operatively. Statistical analysis was performed using SPSS v.27.0 and GraphPad Prism v.9.0. The median and 95% confidence intervals were used to describe data. Logistic regression and χ2 tests were used to describe the associations. We followed the Declaration of Helsinki guidelines. RESULTS Fifty right and 35 left cataract eyes were operated on (58.8% were females; average age 72.8 ± 8.146 years). Total PCMO incidence was 10.6%, and true PCMO incidence (removing PCMO risk factors) was 4.2% at week 6 post-operatively. CST was slightly increased between pre- and post-cataract surgery at week 4 (p = 0.002) and week 6 (p < 0.0001; median = 259 μm, 264 μm, and 263 μm, respectively). IOP was found to be decreased (p < 0.0001) compared to day 1 (median = 17 mm Hg) and week 6 (median = 13 mm Hg). The probability of developing PCMO (odds ratio [OR] = 3) and vitreomacular traction (OR = 2.9) was higher in diabetic patients compared to non-diabetic patients and in patients >65 years old (OR = 1.5). CONCLUSION The true incidence of PCMO was found to be the greatest at 2-4 weeks post-operatively. Patients with diabetes or advanced age (>65 years) are at an elevated risk of developing PCMO after cataract surgery. The treatment regimens for the comorbid populations, especially diabetic patients, remain limited, and future efforts should target pharmaceutical management for these groups.

Abstract
PURPOSE To study the association between different hypoglycemic regimens and postoperative diabetic macular edema (DME). METHODS A secondary analysis based on a retrospective cohort study. RESULTS In this secondary analysis, 124 eyes from patients with proliferative diabetic retinopathy (PDR) who underwent pars plana vitrectomy (PPV) between January 2008 and September 2012 were included. We found that compared with oral hypoglycemic medication, oral hypoglycemic medication plus insulin treatment revealed an insignificant relationship with postoperative DME (odds ratio [OR]=0.8, 95% confidence interval [CI]: 0.12-5.21, P=0.8167), only insulin treatment revealed a significant association with postoperative DME (OR=0.10, 95% CI: 0.01-0.84, P=0.0337) after adjusted age, sex. After adjusted age, sex, diabetes mellitus (DM) duration, glycosylated hemoglobin (HbA1c), the results did not have obvious changes (OR=0.61, 95% CI: 0.09-4.26, P=0.6187; OR=0.07, 95% CI: 0.01-0.65, P=0.0197). Furthermore, after adjusted age, sex, DM duration, HbA1c, hypertension, intraoperative retinal photocoagulation, vitreous hemorrhage, macular detachment, fibrovascular membrane, intraocular lens implantation and microincision vitrectomy surgery, the results were consistent (OR=0.66, 95% CI: 0.05-9.49, P=0.7621; OR=0.06, 95% CI: 0.00-0.81, P=0.0342). The same trend was observed in these adjusted models as well (p for trend was 0.0254, 0.0141, and 0.0311, respectively). CONCLUSION In conclusion, our results of the secondary analysis should be interpreted as a significant association between insulin treatment and reduced risks of postoperative DME in Japanese PDR patients with PPV surgery, compared with oral medications. Well glycemic control with longstanding insulin therapy may be beneficial to reduce the risks of postoperative DME in PDR patients. Our investigation calls for large-scale and long-term prospective clinical studies for a full evaluation of the exact role of insulin in the progression of postoperative DME.

Abstract
PURPOSE OF REVIEW Given the epidemiology and demographic trends of diabetes mellitus and cataracts, ophthalmologists are likely to encounter patients with both comorbidities at an increasing frequency. Patients with diabetes represent a higher risk population than healthy patients for cataract surgery. In this review, we discuss key risks and risk-mitigation practices when performing cataract surgery on these patients. RECENT FINDINGS Patients with diabetes continue to represent a high-risk surgical population: Nagar et al. suggest a dose-dependent relationship may exist between number of intravitreal injections and likelihood of posterior capsular rupture. However, novel treatments are improving outcomes for patients with diabetes. Several studies have reported intracameral phenylephrine/ketorolac may reduce the incidence of post-operative cystoid macular edema while others have discussed the efficacy of pre-treatment and post-treatment with intravitreal bevacizumab on improving cataract surgery outcomes in patients with diabetic retinopathy. Pre-operatively, ophthalmologists should perform an enhanced evaluation, consider timing and lens selection decisions, and complete any appropriate pre-operative treatment. Peri-operatively, surgeons should be aware of pupillary dilation adjustments, combination surgery options, and potential complications. Post-operatively, clinicians should address pseudophakic cystoid macular edema, diabetic macular edema, diabetic retinopathy, and posterior capsular opacification.

Abstract
The management of diabetic retinopathy (DR) has evolved considerably over the past decade, with the availability of new technologies (diagnostic and therapeutic). As such, the existing Royal College of Ophthalmologists DR Guidelines (2013) are outdated, and to the best of our knowledge are not under revision at present. Furthermore, there are no other UK guidelines covering all available treatments, and there seems to be significant variation around the UK in the management of diabetic macular oedema (DMO). This manuscript provides a summary of reviews the pathogenesis of DR and DMO, including role of vascular endothelial growth factor (VEGF) and non-VEGF cytokines, clinical grading/classification of DMO vis a vis current terminology (of centre-involving [CI-DMO], or non-centre involving [nCI-DMO], systemic risks and their management). The excellent UK DR Screening (DRS) service has continued to evolve and remains world-leading. However, challenges remain, as there are significant variations in equipment used, and reproducible standards of DMO screening nationally. The interphase between DRS and the hospital eye service can only be strengthened with further improvements. The role of modern technology including optical coherence tomography (OCT) and wide-field imaging, and working practices including virtual clinics and their potential in increasing clinic capacity and improving patient experiences and outcomes are discussed. Similarly, potential roles of home monitoring in diabetic eyes in the future are explored. The role of pharmacological (intravitreal injections [IVT] of anti-VEGFs and steroids) and laser therapies are summarised. Generally, IVT anti-VEGF are offered as first line pharmacologic therapy. As requirements of diabetic patients in particular patient groups may vary, including pregnant women, children, and persons with learning difficulties, it is important that DR management is personalised in such particular patient groups. First choice therapy needs to be individualised in these cases and may be intravitreal steroids rather than the standard choice of anti-VEGF agents. Some of these, but not all, are discussed in this document.

Abstract
Purpose To assess whether aqueous flare is related to an increased risk of pseudophakic cystoid macular edema (PCME) following uneventful cataract surgery in nondiabetic and diabetic patients. Methods A post hoc analysis of five consecutive randomized clinical trials in the Department of Ophthalmology, Kymenlaakso Central Hospital, Finland. Aqueous flare levels were recorded in 448 eyes of 448 patients before surgery, and after the course of topical anti-inflammatory treatment 28 days and three months after cataract surgery. Results Aqueous flare increase of <50%, ≥50%, ≥100%, and ≥200% associated in central subfield macular thickness (CSMT) increase across the groups at 28 days and three months after surgery. Increase of aqueous flare ≥100% compared to those with <100% was associated with increased CSMT (P = 0.022 at 28 days, and P = 0.027 at three months). At three months, macular thickening (at least 10% CSMT increase) was observed in 12.7% compared to 4.6% of eyes when using a cutoff value of 100% increase in aqueous flare (P = 0.033). Although diabetic patients presented higher aqueous flare levels at baseline compared to nondiabetic patients (12.9 ± 11.8 vs. 9.8 ± 8.2 photon units/ms P < 0.001), the postoperative levels illustrated a similar profile in aqueous flare increase between the two groups. Conclusions At 28 days, aqueous flare increase was associated with macular thickening. A 100% cutoff value could potentially be used when studying anti-inflammatory efficacy of different treatment protocols. Flare values exceeding this cutoff value could be considered as an indication for extending anti-inflammatory therapy. Translational Relevance A 100% increase in aqueous flare at 28 days after cataract surgery from baseline predicted macular thickening up to three months postoperatively. Identifying a correlation between increased aqueous flare levels and pseudophakic cystoid macular edema may allow recognition of the most vulnerable patients, development of prophylactic treatment strategies and reduction of the number and severity of postoperative complications.

Clinical Observation of Phacoemulsification Combined with Intravitreal Injection of Conbercept in Cataract Patients with Diabetic Macular Edema. J Ophthalmol 2021; 2021:8849730. [PMID: 33628483 PMCID: PMC7884183 DOI: 10.1155/2021/8849730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 01/10/2021] [Accepted: 01/25/2021] [Indexed: 11/17/2022] Open
Abstract
Aim To observe the clinical efficacy and safety of phacoemulsification surgery combined with intravitreal injection of conbercept in cataract patients with DME. Methods This is a prospective clinical cohort study. Thirty-five cataract patients (49 eyes) with DME were divided into two groups. The observation group (23 eyes) underwent a cataract phacoemulsification surgery combined with intravitreal injection of conbercept 0.5 mg; the control group (26 eyes) underwent a cataract phacoemulsification surgery only. The visual acuity, central macular thickness (CMT), IOP, and anterior chamber flare were examined before surgery and 1 week and one month after surgery. Results The UCVA and BCVA in Log MAR in the observation group were lower than those in the control group at 1 week (p=0.032; p=0.041) and 1 month (p=0.035; p=0.039), respectively, after the surgery. The CMT of the observation group changed from 492.7 ± 32.2 μm before surgery to 341.6 ± 59.9 μm one week after surgery and 374.8 ± 48.3 μm one month after surgery. The CMT of control group increased after surgery. There was no significant difference in IOP and flare between the two groups at all following times. Conclusion In patients with DME, undergoing a cataract surgery combined with intravitreal injection of conbercept is safe and effective for visual improvement and CMT declination with relatively fewer IOP and flare fluctuation.

[PMID: 32967137 PMCID: PMC7563612 DOI: 10.3390/jcm9093034] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 09/05/2020] [Accepted: 09/14/2020] [Indexed: 01/15/2023] Open
Abstract
Background: To evaluate the clinical course of pseudophakic cystoid macular edema (PCME) treated with topical non-steroidal anti-inflammatory drugs (NSAIDs). Methods: An analysis of the clinical course of PCME consisting of 536 eyes of 536 patients from five consecutive randomized clinical trials aimed at the optimization of anti-inflammatory medication in patients undergoing routine cataract surgery. PCME was classified as (i) grade 0a; no macular thickening, (ii) grade 0b; macular thickening (central subfield macular thickness (CSMT) increase of at least 10%) without signs of macular edema, (iii) grade I; subclinical PCME, (iv) grade II; acute PCME, (v) grade III; long-standing PCME. Eyes with PCME classification from grade I onwards were treated with nepafenac 1 mg/mL t.i.d. for two months. Results: CSMT increase of at least 10% at any postoperative timepoint with cystoid changes—a criterion for PCME—was found in 19 of 536 eyes (total incidence 3.5%). Of these 19 eyes, 13 eyes (total incidence 2.4%) had clinically significant PCME. PCME was considered clinically significant when both of the following visual acuity criteria were fulfilled. At any timepoint after the cataract surgery both the corrected distance visual acuity (CDVA) gain was less than 0.4 decimals from that of preoperative CDVA, and the absolute CDVA level remained below 0.8 decimals. Only one of the 19 eyes with criteria for PCME (total incidence 0.2%, incidence of PCME eyes 5.3%) showed no macular edema resolution within 2 months after topical nepafenac administration. Conclusions: PCME in most cases is self-limiting using topical nepafenac without any further need for intravitreal treatment.

Abstract
Background To evaluate macular microvascular changes and associated factors in diabetic patients following uncomplicated phacoemulsification surgery. Methods In this prospective observational study, we enrolled diabetic patients and non-diabetic controls who underwent phacoemulsification surgery. Participants were examined at postoperative day 1 (POD1), 10 (POD10), 30 (POD30), and 90 (POD90), using macular 3x3mm OCT angiography scan (RTVue-XR Avanti; Optovue, Inc., Fremont, CA). Integrated automated algorithms were used to quantify parafoveal vessel density (VD) in superficial capillary plexus (SCP) and deep capillary plexus (DCP). To minimize measurement bias, subjects with corneal edema or capsular opacity at any postoperative visit were excluded. Results The study included 21 eyes of 21 diabetic patients and 21 eyes of 21 non-diabetic controls. In diabetic patients, no significant change in SCP-VD could be detected (P = 0.57); DCP-VD reduced from 50.24 ± 2.33% at POD1 to 48.33 ± 3.07% at POD30 (P = 0.019), and restored to 50.74 ± 3.44% at POD90 (P = 1.00). The DCP-VD change at POD30 in diabetic patients (− 1.90 ± 2.61%) was significantly different from that in controls (1.31 ± 2.61%) (P < 0.001). The amount of DCP-VD reduction was correlated with foveal and parafoveal thickening (r = 0.431, P = 0.051 and r = 0.514, P = 0.017, respectively), high cumulative dissipated energy (P = 0.032) and increased hemoglobin A1c concentration (P = 0.037). Conclusions Phacoemulsification in diabetic patients caused transient reduction in DCP-VD, which was associated with poor glycemic control, surgical trauma, and postoperative macular thickening. Our results added a new dimension to our understanding of the complex biologic effects of cataract surgery in diabetic subjects.

Preoperative central macular thickness as a risk factor for pseudophakic macular edema. Graefes Arch Clin Exp Ophthalmol 2020; 259:37-43. [PMID: 32783096 DOI: 10.1007/s00417-020-04862-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 07/21/2020] [Accepted: 07/23/2020] [Indexed: 10/23/2022] Open
Abstract
PURPOSE This study aims to determine whether elevated central macular thickness (CMT) before uncomplicated cataract surgery may be a risk factor for developing cystic macular edema (CMEs) as measured by Cirrus-OCT and defined as the presence of macular intraretinal cysts. METHODS A prospective study in Hospital Universitario Poniente, Almeria, Spain, where 379 patients were included for optical coherence tomography (OCT) before cataract surgery, the following day, at 1 month and at 3 months and the presence of macular intraretinal cysts assessed by OCT. Patients with known risk factors for developing CME and patients who developed major surgical complications were excluded. RESULTS One hundred seventy-nine patients completed the study. The pre-surgical CMT was 257.75 (20.60) μm measured by Cirrus-OCT. After 1 month, there was an average increase in CMT of 277.86 (45.29) μm, and this increase in thickness decreased after 3 months to an average value of 267.86 (20.17) μm. There were 10.34% of patients with cysts in some of the controls after surgery. This study proposes a binary logistic model to predict the presence of CME depending on the pre-surgery CMT. The cut-off point was 260.5 μm. CONCLUSION Patients with pre-surgical macular thickness > 260.5 μm measured by Cirrus- OCT before cataract surgery, no known risk factors for developing CME and no major surgical complications presented 9.08 times more probability to develop macular intraretinal cysts after uncomplicated cataract surgery.

Abstract
PURPOSE Novel pupil expansion devices are widely recognized for their intraoperative feasibility in safe small pupil cataract surgeries. To assess whether the use of pupil expansion devices affects recovery from cataract surgery. METHODS A post hoc analysis of five consecutive prospective randomized clinical trials. 536 eyes of 536 patients undergoing routine cataract surgery were analysed according to the use of pupil expansion device. Thirty-four eyes were operated with pupil expansion device and 502 eyes without. Clinical outcome parameters were recorded at 28 days and 3 months. RESULTS Patient age and gender distribution, and baseline clinical outcome parameters were comparable between study groups. Pseudoexfoliation syndrome, glaucoma and medication for benign prostatic hyperplasia were more frequently present; phacoemulsification energy was higher and operation time longer in eyes with pupil expansion device. At 28 days, aqueous flare increased by 12.0 ± 25.1 pu/mseconds and mean central subfield macular thickness by 16.2 ± 24.4 μm in eyes with pupil expansion device, when compared to 4.6 ± 14.8 pu/mseconds (p = 0.015) and 7.0 ± 33.9 μm (p = 0.064) in eyes without the device. At 3-month follow-up, clinically significant pseudophakic cystoid macular edema (PCME) was reported in 12% of eyes with pupil expansion device and in 2% of eyes without (p = 0.006). After adjusting for the presence of confounding factors, hazard for clinically significant PCME was greater in eyes with pupil expansion device than in those without (HR 5.41, 95% CI 1.35-21.71, p = 0.017). CONCLUSIONS The use of pupil expansion device may predispose eyes to increased risk of clinically significant PCME. Effective anti-inflammatory treatment and follow-up are warranted in eyes with pupil expansion device.

Abstract
PURPOSE To examine preoperative anti-inflammatory treatment on recovery from cataract surgery in eyes of diabetic patients. METHODS A Prospective randomized clinical trial. One hundred and three eyes of 103 patients with diabetes undergoing routine cataract surgery were randomized (1:1) not to receive any preoperative anti-inflammatory medication or to receive preoperative topical anti-inflammatory medication with a combination of prednisolone acetate (10 mg/ml) and nepafenac (1 mg/ml). All eyes received postoperative anti-inflammatory combination therapy for 3 weeks. Recovery from surgery was recorded by a structured home questionnaire. Clinical outcome parameters were recorded at 28 days and 3 months. RESULTS Patient age and gender distribution, and all baseline ophthalmic and systemic parameters were comparable between the study groups. After surgery, conjunctival injection lasted 2.4 ± 1.7 days (mean ± SD) and irritation of the eye 3.3 ± 3.9 days in eyes without preoperative treatment, when compared to 1.6 ± 1.6 days (p = 0.067) and 2.4 ± 4.0 days (p = 0.431), respectively, in eyes with preoperative treatment. At 28 days, central subfield macular thickness (CSMT) increased 2.2 ± 20.2 μm in eyes without preoperative treatment, when compared 0.1 ± 25.2 μm (p = 0.670) in eyes with preoperative treatment. At 3 months, the respective CSMT change from baseline was -1.5 ± 26.9 μm and -3.4 ± 26.2 μm (p = 0.762). None of the eyes were reported with pseudophakic cystoid macular oedema (PCME) in either group. CONCLUSION Lack of preoperative anti-inflammatory treatment does not impair recovery from surgery or predispose diabetic patients to increased risk of PCME in eyes postoperatively treated with combination therapy of prednisolone acetate and nepafenac.

Abstract
Diabetes mellitus is one of the most prevalent chronic diseases worldwide. Diabetic patients are at risk of developing cataract and present for surgery at an earlier age than non-diabetics. The aim of this study was to review the problems associated with cataract surgery in a diabetic patient. Corneal complications in diabetic patients include delayed wound healing, risk of developing epithelial defects or recurrent erosions due to the impairment of epithelial basement membranes and epithelial-stromal interactions. Diabetic patients present lower endothelial cell density and their endothelium is more susceptible to trauma associated with cataract surgery. A small pupil is common in diabetic patients making cataract surgery technically challenging. Finally diabetic patients have an increased risk for developing postoperative pseudophakic cystoid macular edema, posterior capsule opacification or endophthalmitis. In patients with pre-proliferative or proliferative diabetic retinopathy, diabetic macular edema or iris neovascularization adjunctive therapy such as an intravitreal anti-vascular endothelial growth factor injection, can inhibit exacerbation related to cataract surgery.

Abstract
PURPOSE To examine the role of systemic medication on the risk of pseudophakic cystoid macular edema (PCME) following uneventful cataract surgery. METHODS A total of 269 eyes undergoing routine cataract surgery. Spectral-domain optical coherence tomography imaging was conducted before surgery and at 28 days. Information about medication of the participants was gathered from The National Archive of Health Information (Kanta), an electronic pharmaceutical database. RESULTS Systemic medication with angiotensin converting enzyme inhibitor/angiotensin II receptor antagonists (p < 0.001), beta-blockers (β-blockers) (p = 0.002), calcium channel blockers (CCBs) (p < 0.001), nitrates (p =0.021) and lipophilic HMG-CoA reductase inhibitors (statins) (p < 0.001) were more frequently prescribed to diabetic compared with nondiabetic patients. In eyes with steroid monotherapy (N = 135), concomitant systemic medication with β-blockers (12.9 ± 24.0 μm versus 28.6 ± 59.5 μm, p = 0.045), CCBs (12.0 ± 22.1 μm versus 26.3 ± 55.6 μm, p = 0.041) and statins (12.9 ± 22.8 μm versus 30.0 ± 61.9 μm, p = 0.038) attenuated a change in central retinal thickness (CRT) when compared to patients not receiving medication. In multivariable analysis, the use of CCBs remained as an independent protective factor against macular swelling at 28 days (-0.23; 95% CI [-0.43 to -0.04]; p = 0.021), when all systemic medications showing statistical significance were included (i.e. β-blockers, CCBs and statins) together with diabetes status. In eyes with nonsteroidal anti-inflammatory drug (NSAID) monotherapy (N = 67) and steroid and NSAID combination therapy (N = 67), CRT increase was moderate both with and without use of systemic medications. CONCLUSION Systemic vasoactive medication may be protective against CRT change induced by cataract surgery in eyes at risk of PCME such as those with postoperative steroid monotherapy.

Abstract
PURPOSE To study the outcomes of uneventful cataract surgery in diabetic patients without retinal complications. DESIGN A post hoc treatment analysis using data from 2 double-masked randomized clinical trials. METHODS Setting: Conducted at Kymenlaakso Central Hospital, Kotka, Finland. PROCEDURE A total of 276 eyes of 266 patients undergoing routine cataract surgery were included in the study. Patients with type I or II diabetes (n = 56 eyes) were compared to nondiabetic patients (n = 220 eyes). Clinical evaluation was conducted by the operating physician, and outcome measures taken before surgery and day 28 were recorded by a research technician. RESULTS Patient age, sex distribution, and all baseline ophthalmic and surgical parameters were comparable for the nondiabetic and diabetic patient groups. Increase in aqueous flare 6.3 ± 16.4 photon units (pu)/ms vs 3.7 ± 8.9 pu/ms (mean ± standard deviation; P = .282), central retinal thickness (CRT) 12.0 ± 38.2 μm vs 5.9 ± 15.8 μm (P = .256), corrected distance visual acuity 0.57 ± 0.31 decimals vs 0.53 ± 0.35 decimals (P = .259), and patient satisfaction 9.3 ± 0.9 vs 9.2 ± 1.1 (P = .644) were comparable for nondiabetic and diabetic patients. In eyes with steroid monotherapy (n = 64), CRT increased 38.1 ± 72.8 μm in nondiabetic patients compared to 7.8 ± 6.6 μm in diabetic ones (P = .010). In eyes with nonsteroidal anti-inflammatory drug (NSAID) monotherapy (n = 157), CRT increased 5.7 ± 18.4 μm in nondiabetic patients compared to 6.2 ± 20.5 μm in diabetic ones (P = .897). Among eyes with steroid and NSAID combination therapy (n = 55), CRT increased 3.6 ± 4.1 μm in nondiabetic patients compared to 2.9 ± 3.2 μm in diabetic ones (P = .606). At 28 days postsurgery, pseudophakic cystoid macular edema (PCME) was reported in 8 eyes, of which 7 were in nondiabetic patients (P = 1.000). CONCLUSIONS Diabetic patients showed less change in CRT when compared to controls in steroid monotherapy. Other outcome measurements shows no statistical differences.

Abstract
Abstract
Introduction
In 2017, over 75,000 cataract surgeries were performed within the Veterans Health Administration System (VHA). Previous reports of outcomes of cataract surgery in veterans include patients with pre-existing ocular disease, which can affect vision. To exclude the confounding factor of pre-existing ocular comorbidities, we investigated the long-term visual outcomes and complications associated with small incision cataract surgery performed on veterans without any pre-existing eye disease.
Materials and Methods
Institutional Review Board approved cohort study with detailed retrospective chart review of all phacoemulsification (small incision) cataract surgeries performed at the Veterans Affairs Medical Center in Washington D.C. over 11 years, including all pre-and postoperative visits until postoperative month 12.
Results
A total of 1,513 consecutive surgical cases without any pre-existing ocular disease except the cataract were included. Vision improved significantly after cataract surgery compared to the preoperative best-corrected visual acuity (BCVA) (p = 0.0001) and remained stable over the first intra- and postoperative year. All eyes without complicated surgery and 99.1% of eyes with complications achieved 20/40 or better final vision postoperatively. The most common intra-and postoperative complications were vitreous loss (3.1%) and cystoid macular edema (CME; 1.4%). Patients with complications achieved final mean BCVA of 0.04 (20/22, vitreous loss) and 0.06 (20/23, CME) mean logMAR (Snellen).
Conclusion
Analysis of 11 years of small incision cataract surgery in eyes without pre-existing ocular disease within the VHA showed significant improvement in vision and stability 12 months after uncomplicated and complicated surgery in veterans.

Abstract
Diabetes mellitus (DM) is the most common endocrine disease, and therefore a pressing medical and social problem. In many cases, ocular manifestations of DM are considered the particular cause of patients' disability. The review presents an analysis of morphological, experimental and clinical studies of the cornea in patients with diabetes mellitus - full articles, reviews and monographs of Russian and foreign authors, mostly those published in the recent years. Among the considered topics are modern methods of examining conjunctiva and cornea, clinical and morphological changes in these tissues, and the early diabetic changes in all their structural layers. The review also describes the importance of diabetes-related changes in the conjunctival vessels and corneal nerve fibers and shows the correlation between the densities of corneal nerve fibers and epidermal nerve fibers.
