In this issue, Rabiolo and associates1 report on their literature review of criteria for failure in glaucoma surgery, stating that, compared with intraocular pressure (IOP) criteria, “Long-term visual field rates provide a more consistent primary outcome measure” and suggest that they “be incorporated into composite success criteria.”

HIGHLIGHTS
Blue light-filtering IOLs did not reduce exudative age-related macular degeneration (AMD) risk in this large cohort study.
Outcomes were comparable across sex, age, and history of nonexudative AMD.
Abstract
Purpose
To evaluate whether blue light-filtering (BLF) intraocular lenses (IOLs) reduce the risk of exudative age-related macular degeneration (AMD).
Design
A nationwide, population-based cohort study using data from the Korean National Health Insurance Sharing Service (NHISS) database.
Participants
Individuals who underwent cataract surgery and received the same type of IOL (BLF or clear) in both eyes within one year between January 2012 and December 2018.
Participants were categorized into BLF IOL or clear IOL groups, and the risk of exudative AMD was compared between the 2 groups. The 10-year cumulative incidence of exudative AMD was estimated using Kaplan-Meier analysis. Cox proportional hazard models and the Fine-Gray model were applied to calculate adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs), adjusting for age, sex, socioeconomic status, and systemic diseases. The same analysis was performed in the cohort matched by age, sex, and the calendar year of the index date.
Main outcome measures
10-year cumulative incidence, incidence rate, and HR for exudative AMD.
A total of 21,741 individuals with BLF IOLs were compared to 56,357 individuals with clear IOLs. The mean follow-up duration was 7.0 ± 2.5 years in the BLF IOL group and 6.7 ± 2.5 years in the clear IOL group (P = .069). The 10-year cumulative incidence of exudative AMD was 1.8% (95% CI, 1.5%–2.0%) in the BLF IOL group and 1.7% (95% CI, 1.5%-1.8%) in the clear IOL group. The incidence rates per 100,000 person-years were 162.8 and 153.9 in the BLF IOL group and clear IOL groups, respectively, with no significant difference in the adjusted Cox model (aHR 1.12; 95% CI, 0.96-1.30; P = .149) and the Fine-Gray model (aHR 1.15; 95% CI, 0.97-1.36; P = .120). Subgroup analyses based on age, sex, and history of nonexudative AMD showed no protective effect of BLF IOLs, with comparable incidence rates across all subgroups. Similar results were observed in the matched cohort analysis.
Conclusions
BLF IOL implantation in cataract surgery does not reduce the risk of developing exudative AMD in the South Korean population, regardless of a history of nonexudative AMD.
