“…In summary, the rates of cataract surgery in the U.S. have increased in the past few decades. 5,31,32 Vision loss related to cataract progression can have an enormous impact on the health and well-being of a icted individuals. 8, [17][18][19][20][21][22][23] Disparities exist with regard to the visual acuity at which cataract surgery is initiated in different patient populations.…”

Purpose Access to and utilization of cataract surgery varies nationally. The purpose of this study was to characterize sociodemographic factors that predict best corrected visual acuity (BCVA) at the time of cataract surgery. Design: Retrospective cohort study. Methods This is a multicenter study of nearly 2.4M patients ≥ 50 years of age in the national IRIS® (Intelligent Research in Sight) Registry who had ≥ one BCVA measurement six months preceding cataract surgery. Estimating the relationship between race and ethnicity and preoperative BCVA, within and between ophthalmology practices, was the main outcome measure. Results Within a practice, preoperative BCVA was approximately 0.05 logarithm of the minimum angle of resolution (logMAR) lower for patients identified as White compared to all other racial and ethnic groups (p < 0.002). Uninsured and Medicaid-insured patients had worse preoperative BCVA (1.150, 0.097 logMAR higher, p = 0.006, 0.001, respectively). Between practices, a patient in a practice serving 10 percent more patients identified as Asian, Black, or Hispanic had higher preoperative BCVA, holding constant an individual’s race and ethnicity (0.009, 0.012, 0.014 logMAR higher, respectively, all p = 0.002). Conclusions Our results suggest that patients who do not identify as White, uninsured, and Medicaid-insured patients, will have worse vision prior to cataract surgery. Further, we observed that patients seen at practices serving a higher percentage of patients identified as Asian, Black, or Hispanic will have worse preoperative BCVA. These findings highlight the need for initiatives to address disparities in ophthalmic care.

“…[9] However, there are also publications reporting no difference in the number of cataract surgeries when looking at yearly data. [10] The fact that our hospital is the referral hospital in the region and full-capacity surgery is performed before and after the pandemic may be a reason why the number of surgeries has not decreased. In addition, since no elective surgery was performed during the closure period in our study, this period was excluded from the study.…”

The purpose of this study was to compare the clinical features of pre-pandemic and pandemic patients who had elective cataract surgery in our hospital. Methods: This study is a retrospective study. Cataract surgeries performed in our clinic between March 2019 and June 2021 were screened. Patient's age, gender, eye laterality, cataract type, preoperatively best-corrected visual acuity (BCVA) in the eye with a cataract, pseudoexfoliation, and other compelling factors for surgery were noted. Considering that there was no elective cataract surgery in our hospital between March 2020 and June 2020 due to the COVID-19 pandemic, 1-year data before March 2020 and 1-year data after June 2020 were included in the study. Patient data from these two periods were compared with each other. Results: The pre-pandemic and pandemic groups had 560 eyes of 489 patients and 590 eyes of 534 patients, respectively. The patients in the pre-pandemic group were significantly older than those in the pandemic group (69 vs. 67 years, P=0.046). The mean BCVA differs according to the groups (0.163±0.148 vs. 0.130±0.132) (P<0.001). The rate of blindness was significantly higher in the pandemic group than in the pre-pandemic group (39.3% vs. 31.4, P=0.006). There was no difference in the number of brown/mature cataracts between the two periods (P:0.629). Diabetic retinopathy was significantly lower during the pandemic period. The number of traumatic cataracts increased substantially during the pandemic. Conclusion:We encountered cataract patients with lower pre-operative best-corrected visual acuity during the pandemic.

“…Cataracts are a leading cause of visual impairment among adults in the US, with the prevalence of cataract expected to double to about 50 million persons by 2050. 7 Cataract surgery is among the most commonly performed surgical procedures in adults in the US, with an estimated 3.8 million such surgeries performed in 2017 8 and a projected annual increase of 5.6%. 9 Advances in IOL materials and design, phacoemulsification technology, and surgical techniques have enhanced surgical success rates and simultaneously increased patients’ expectations for high-quality VA, particularly following implantation of premium IOLs for correction of astigmatism and/or presbyopia.…”

To evaluate absolute prediction errors following phacoemulsification with implantation of a multifocal toric intraocular lens (IOL) using intraoperative aberrometry for IOL power selection and to compare findings with the globally optimized and manufacturer's recommended lens constants and regression coefficients. Methods: Data from the Optiwave Refractive Analysis (ORA SYSTEM) were analyzed retrospectively. Absolute prediction errors from surgeries performed before and after the first optimization of the manufacturer's recommended lens constant and non-optimized regression coefficients for the multifocal toric IOL (SND1T3-6) were compared. Optimization was based on outcomes of procedures performed using the ORA SYSTEM and archived in its database (AnalyzOR). Outcome measures included the proportion of eyes with absolute ORA SYSTEM prediction errors ≤0.25 D and ≤0.5 D and the mean and median absolute prediction errors. Results:The pre-optimization group included 1027 eyes operated on by 184 surgeons, and the optimized group included 419 eyes operated on by 143 surgeons. The proportions of eyes achieving absolute ORA SYSTEM prediction errors ≤0.25 D (52.5% vs 35.0%, p < 0.0001) and ≤0.50 D (83.1% vs 66.2%, p < 0.0001) were significantly higher in the optimized than in the pre-optimization group. The mean ± standard deviation (0.30 ± 0.25 D vs 0.43 ± 0.32 D, p < 0.0001) and median (0.24 D vs 0.36 D, p < 0.0001) absolute ORA SYSTEM prediction errors were significantly lower after than before optimization. Prediction errors following optimization were reduced more in eyes of average than of long and short axial lengths. Conclusion: Global optimization of the manufacturer's IOL lens constants and regression coefficients resulted in lower absolute prediction errors when compared with the initial manufacturer labeled lens constants and non-optimized regression coefficients. Reductions in absolute prediction error can result in lower postoperative residual refractive error, which can improve post-operative uncorrected visual acuity and provide the potential for greater patient satisfaction following cataract surgery.
