Study Summary
This study was a retrospective observational cohort analysis of subjects aged 65 years and older, who underwent bilateral cataract surgery within a single (15 hospital) healthcare system, to determine the association between type (conventional or blue-light filtering) of implanted intraocular lens and survival.
Primary Outcome
The primary outcome was all-cause mortality. Mortality was identified based on the Social Security Death Master File and discharge status. Follow-up started from the day after the initial surgery until the end of the study period or death, whichever occurred first. Time to death was calculated as the number of days from the first cataract surgery to death. Participants who did not have a recorded death were censored on April 30, 2019.
