Impact of First Eye versus Second Eye Cataract Surgery on Visual Function and Quality of Life.

PURPOSE: To compare the impact of first eye versus second eye cataract surgery on visual function and quality of life. DESIGN: Cohort study. PARTICIPANTS: A total of 328 patients undergoing separate first eye and second eye phacoemulsification cataract surgeries at 5 veterans affairs centers in the United States. Patients with previous ocular surgery, postoperative endophthalmitis, postoperative retinal detachment, reoperation within 30 days, dementia, anxiety disorder, hearing difficulty, or history of drug abuse were excluded. METHODS: Patients received complete preoperative and postoperative ophthalmic examinations for first eye and second eye cataract surgeries. Best-corrected visual acuity (BCVA) was measured 30 to 90 days preoperatively and postoperatively. Patients completed the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ) 30 to 90 days preoperatively and postoperatively. The NEI-VFQ scores were calculated using a traditional subscale scoring algorithm and a Rasch-refined approach producing visual function and socioemotional subscale scores. MAIN OUTCOME MEASURES: Postoperative NEI-VFQ scores and improvement in NEI-VFQ scores comparing first eye versus second eye cataract surgery. RESULTS: Mean age was 70.4 years (±9.6 standard deviation [SD]). Compared with second eyes, first eyes had worse mean preoperative BCVA (0.55 vs. 0.36 logarithm of the minimum angle of resolution (logMAR), P < 0.001), greater mean BCVA improvement after surgery (-0.50 vs. -0.32 logMAR, P < 0.001), and slightly worse postoperative BCVA (0.06 vs. 0.03 logMAR, P = 0.039). Compared with first eye surgery, second eye surgery resulted in higher postoperative NEI-VFQ scores for nearly all traditional subscales (P < 0.001), visual function subscale (-3.85 vs. -2.91 logits, P < 0.001), and socioemotional subscale (-2.63 vs. -2.10 logits, P < 0.001). First eye surgery improved visual function scores more than second eye surgery (-2.99 vs. -2.67 logits, P = 0.021), but both first and second eye surgeries resulted in similar improvements in socioemotional scores (-1.62 vs. -1.51 logits, P = 0.255). CONCLUSIONS: Second eye cataract surgery improves visual function and quality of life well beyond levels achieved after first eye cataract surgery alone. For certain socioemotional aspects of quality of life, second eye cataract surgery results in comparable improvement to first eye cataract surgery.

Yearly Treatment Patterns for Patients with Recently Diagnosed Diabetic Macular Edema.

PURPOSE: To describe the treatment patterns and the predictors of different treatment standards in recently diagnosed diabetic macular edema (DME) patients in a nationally representative sample. DESIGN: A retrospective cohort study using administrative claims data from January 1, 2007, through March 31, 2015. Patients were grouped into yearly cohorts. PARTICIPANTS: A total of 96 316 patients were included. METHODS: Patients with a diagnosis of DME were identified using International Classification of Diseases, Ninth Edition, Clinical Modification, codes. Predictors of anti-vascular endothelial growth factor (VEGF) use and number of anti-VEGF injections per patient were assessed using generalized linear regression (logistic and negative binomial, respectively), and yearly trends in different treatments were analyzed with Mann-Kendall tests. MAIN OUTCOME MEASURES: Predictors of anti-VEGF treatment and of anti-VEGF injections per patient and the changes in relative use of DME therapies per cohort. RESULTS: Among those with any treatment, the odds of being prescribed anti-VEGF therapy increased by 700% from 2009 to 2014 and by 154% for those seen by a retina specialist. Those in the cohort of year 2014 received 3.5 times more injections than those in 2009, whereas those covered by Managed Medicare, Medicaid, and Medicare received 31%, 24%, and 11% less injections. Anti-VEGF were 11.6% of all DME treatments in 2009 increasing to 61.9% in 2014, while corticosteroids and focal laser procedures dropped from 6.1% to 3% and 75% to 24%, respectively. Procedures per patient (PPP) were much lower than those observed in clinical trials of anti-VEGF. Procedures per patient increased in the cases of aflibercept (from 1 in 2011 to 2.20 in 2014), bevacizumab (from 1.84 in 2009 to 3.40 in 2014), and ranibizumab (from 3.11 in 2009 to 4.48 in 2014), whereas applications of laser procedures and corticosteroids per patient remained roughly stable. CONCLUSIONS: Year of diagnosis and being seen by a retina specialist were important predictors of receiving anti-VEGF therapy, and after one received such therapy, the number of additional injections was smaller for those with government-provided insurance. Anti-VEGF therapy has become a mainstay in DME treatment, with PPP, although relatively low, also increasing.

Outcomes after cataract surgery in eyes with pseudoexfoliation: Results from the Veterans Affairs Ophthalmic Surgery Outcomes Data Project.

OBJECTIVE: To compare clinical outcomes of cataract surgery in eyes with and without pseudoexfoliation (PXF). DESIGN: Retrospective deidentified data analysis. PARTICIPANTS: A total of 123 PXF and 4776 non-PXF eyes of patients who underwent cataract surgery. METHODS: We compared data on visual acuity, Visual Function Questionnaire (VFQ)-based quality of life, and complications in PXF and non-PXF eyes from the Veterans Affairs (VA) Ophthalmic Surgery Outcomes Data Project across 5 VA medical centres. RESULTS: Pupillary expansion devices were used in 31 (25.2%) PXF cases and 398 (8.4%) non-PXF cases (p < 0.0001). Capsular tension rings were used in 6 (4.9%) PXF cases and 55 (1.2%) non-PXF cases (p < 0.004). The following complications occurred more frequently in PXF cases: zonular dehiscence without vitrectomy (4 [3.3%] PXF cases vs 40 [0.8%] non-PXF cases p = 0.02), persistent inflammation (28 [24.1%] vs 668 [14.5%]; p = 0.007), and persistent intraocular pressure elevation (5 [4.3%] vs 68 [1.5%]; p = 0.03). Best corrected visual acuity (BCVA) improved in both groups after 1 month, but 87 (83.7%) PXF cases achieved postoperative BCVA better than or equal to 20/40 compared to 3991 (93.8%) non-PXF cases (p = 0.0003). There was no significant difference in the postoperative composite VFQ scores between PXF (82.1 ± 16.9) and non-PXF cases (84.2 ± 16.8, p = 0.09). CONCLUSIONS: Several complications occurred more frequently in the PXF group compared to the non-PXF group, and fewer PXF cases achieved BCVA better than or equal to 20/40. Despite this, both groups experienced similar improvement in vision-related quality of life after cataract surgery.

Physician-Industry Interactions and Anti-Vascular Endothelial Growth Factor Use Among US Ophthalmologists.

IMPORTANCE: The publication of the US Physician Payments Sunshine Act provides insight into the financial relationship between physicians and the pharmaceutical industry. This added transparency creates new opportunities of using objective data to better understand prior research that implicates pharmaceutical promotions as an important factor in a physician's decision-making process. OBJECTIVE: To assess the association between reported industry payments and physician-prescribing habits by comparing the use of anti-vascular endothelial growth factor (VEGF) intravitreal injections by US ophthalmologists to the industry payments these same physicians received. DESIGN, SETTING, PARTICIPANTS: This study reviews data from the Centers for Medicare & Medicaid Services (CMS) 2013 Medicare Provider Utilization and Payment Data: Physician and Other Supplier Public Use File and the CMS-sponsored August through December 2013 Open Payments program (Physician Payments Sunshine Act). Ophthalmologists who prescribe anti-VEGF injections for all indications were analyzed. MAIN OUTCOMES AND MEASURES: Association between industry payments reportedly received and the number and type of anti-VEGF injections administered. RESULTS: A total of 3011 US ophthalmologists were reimbursed by CMS for 2.2 million anti-VEGF injections in 2013. Of these physicians, 38.0% reportedly received $1.3 million in industry payments for ranibizumab and aflibercept. Analysis revealed positive associations between increasing numbers of reported industry payments and total injection use (r = 0.24; 95% CI, 0.22-0.26; P < .001), aflibercept and ranibizumab injection use (r = 0.32; 95% CI, 0.29-0.34; P < .001), and percentage of injections per physician that were aflibercept or ranibizumab (r = 0.27; 95% CI, 0.25-0.29; P < .001). A smaller association was noted between greater number of industry payments and bevacizumab injection use (r = 0.07; 95% CI, 0.04-0.09; P < .001). Similar associations were found between the total dollars of reported industry payments received to injection use. Subgroup analysis further revealed that physicians receiving $1 to $25 in reported industry benefits were more likely than those not receiving industry payments to perform a greater percentage of their injections with aflibercept and ranibizumab. CONCLUSIONS AND RELEVANCE: Among ophthalmologists who prescribe anti-VEGF medications, there is a positive association between reported pharmaceutical payments and increased use of aflibercept and ranibizumab injections. As is inherent to the design of correlation studies, this analysis cannot determine whether the payments reported caused the increased use, are a result of the increased use, or are merely associated with some other factor that causes the increased use.

American Society of Anesthesiologists classification in cataract surgery: Results from the Ophthalmic Surgery Outcomes Data Project.

PURPOSE: To explore the association of American Society of Anesthesiologists (ASA) classification with cataract surgery outcomes. SETTING: Five Veterans Affairs Medical Centers, United States. DESIGN: Retrospective observational cohort study. METHODS: The study analyzed the outcomes of cataract surgery cases. Corrected distance visual acuity (CDVA), unanticipated events, and vision-related quality of life (VRQL) were assessed using the National Eye Institute Visual Function Questionnaire (NEI-VFQ), comparing ASA classes I through IV. For some analyses, ASA classes I and II were designated as Group A and ASA classes III and IV were designated Group B. RESULTS: Of the 4923 cases, 875 (17.8%) were in Group A, 4032 (81.9%) were in Group B, and 16 (0.3%) had missing data. The mean CDVA and mean composite NEI-VFQ score improved after cataract surgery in both groups (P < .0001); however, Group A had a better mean postoperative CDVA and postoperative VFQ composite scores than Group B (P < .0001, both outcomes). A higher ASA class was associated with an increased risk for 2 unanticipated events; that is, clinically significant macular edema (CSME) (Group A: 4 [0.47%] versus Group B: 50 [1.28%]; adjusted odds ratio [OR], 3.02; 95% confidence interval [CI], 1.02-13.05; P = 0.04) and readmission to the hospital within 30 days (2 [0.23%] versus 56 [1.41%]; OR, 8.26; 95% CI, 1.71-148.62; P = .004) CONCLUSIONS: Among United States veterans, the ASA classification could be an important predictor of VRQL and visual outcomes. In this cohort, it was associated with an increased risk for 2 serious unanticipated events-CSME and readmission to the hospital-both costly, unwanted outcomes.

Cataract Surgery Outcomes in Glaucomatous Eyes: Results From the Veterans Affairs Ophthalmic Surgery Outcomes Data Project.

PURPOSE: To compare visual acuity outcomes, vision-related quality of life, and complications related to cataract surgery in eyes with and without glaucoma. DESIGN: Retrospective cohort study. METHODS: Cataract surgery outcomes in cases with and without glaucoma from the Veterans Affairs Ophthalmic Surgical Outcomes Data Project were compared. RESULTS: We identified 608 glaucoma cases and 4306 controls undergoing planned cataract surgery alone. After adjusting for age, pseudoexfoliation, small pupil, prior ocular surgery, and anterior chamber depth, we found that glaucoma cases were more likely to have posterior capsular tear with vitrectomy (odds ratio [OR] 1.8, P = .03) and sulcus intraocular lens placement (OR 1.65, P = .03) during cataract surgery. Glaucoma cases were more likely to have postoperative inflammation (OR 1.73, P < .0001), prolonged elevated intraocular pressure (OR 2.96, P = .0003), and additional surgery within 30 days (OR 1.92, P = .03). Mean best-corrected visual acuity (BCVA) and Visual Function Questionnaire (VFQ) scores significantly improved after cataract surgery in both groups (P < .0001), but there were larger improvements in BCVA (P = .01) and VFQ composite scores (P < .0001) in the nonglaucoma vs the glaucoma group. A total of 3621 nonglaucoma cases (94.1%) had postoperative BCVA 20/40 or better, compared to 466 glaucoma cases (89.6%) (P = .0003). CONCLUSIONS: Eyes with glaucoma are at increased risk for complications and have more modest visual outcomes after cataract surgery compared to eyes without glaucoma. Despite this, glaucoma patients still experience significant improvement in vision-related outcomes after cataract extraction. Further study is needed to explore potential factors that influence cataract surgery outcomes in glaucomatous eyes.

Functional Visual Improvement After Cataract Surgery in Eyes With Age-Related Macular Degeneration: Results of the Ophthalmic Surgical Outcomes Data Project.

PURPOSE: To determine if cataract surgery on eyes with AMD confers as much functional visual improvement as surgery on eyes without retinal pathology. METHODS: This is a retrospective analysis of 4924 cataract surgeries from the Veterans Healthcare Administration Ophthalmic Surgical Outcomes Data Project (OSOD). We included cases of eyes with AMD that had both preoperative and postoperative NEI-VFQ-25 questionnaires submitted and compared their outcomes with controls without retinal pathology. We excluded patients with other retinal pathologies (740 patients). The analyses compared changes in visual acuity and overall functional visual improvement and its subscales using t-tests, multivariate logistic regressions, and linear regression modeling. RESULTS: Preoperative and postoperative questionnaires were submitted by 58.3% of AMD and 63.8% of no retinal pathology cases (controls). Analysis of overall score showed that cataract surgery on eyes with AMD led to increased visual function (13.8 ± 2.4 NEI-VFQ units, P < 0.0001); however, increases were significantly less when compared with controls (-6.4 ± 2.9 NEI-VFQ units, P < 0.0001). Preoperative best-corrected visual acuity (preBCVA) in AMD was predictive of postoperative visual function (r = -0.38, P < 0.0001). In controls, postoperative visual function was only weakly associated with preBCVA (r = -0.075, P = 0.0002). Patients with AMD with vision of 20/40 or better had overall outcomes similar to controls (-2.2 ± 4.7 NEI-VFQ units, P = 0.37). CONCLUSIONS: Cataract surgery on eyes with AMD offers an increase in functional visual improvement; however, the amount of benefit is associated with the eye's preBCVA. For eyes with preBCVA of 20/40 or greater, the improvement is similar to that of patients without retinal pathology. However, if preBCVA is less than 20/40, the amount of improvement was shown to be significantly less and decreased with decreasing preBCVA.

Intraoperative floppy iris and prevalence of intraoperative complications: results from ophthalmic surgery outcomes database.

PURPOSE: To estimate the prevalence of untoward events during cataract surgery with the use of pupillary expansion devices and intraoperative floppy iris (IFIS). DESIGN: Retrospective analysis of 4923 cataract surgery cases from the Veterans Affairs Ophthalmic Surgical Outcomes Data Project. METHODS: Outcomes from 5 Veterans Affairs medical centers were analyzed, including use of alpha-blockers (both selective and nonselective), IFIS, intraoperative iris trauma, intraoperative iris prolapse, posterior capsular tear, anterior capsule tear, intraoperative vitreous prolapse, and use of pupillary expansion devices. P values were calculated using the χ(2) test. RESULTS: A total of 1254 patients (25.5%) took alpha-blockers preoperatively (selective, 587; nonselective, 627; both, 40). Of these 1254 patients, 428 patients (34.1%) had documented IFIS. However, 75.2% of patients with IFIS (428/569) had taken alpha-blockers preoperatively (P < .00001). A total of 430 patients (8.7%) had a pupillary expansion device used during their cataract surgery, of which 186 patients (43.4%) had IFIS (P < .0001). Eighty-six patients with IFIS had at least 1 intraoperative complication and 39 patients with IFIS had more than 1 intraoperative complication (P < .001). CONCLUSIONS: The use of either selective or nonselective alpha-antagonists preoperatively demonstrated a significant risk of IFIS. Nonselective alpha-antagonists caused IFIS at a higher prevalence than previously reported. This study did demonstrate statistically significant increased odds of surgical complications in patients with IFIS vs those without IFIS in all groups (those taking selective and nonselective alpha-antagonists and also those not taking medications).
