*P values from univariable linear regression analysis.
†For visual acuity at 3 months (ordinal exposures with three categories), the p values were calculated for trend.
‡P values from multivariable linear regression analysis, adjusted for age, education status, wealth category and baseline QoL.
§Eye removal was a priori.
VRQoL, vision-related quality of life.
