Abstract Details

Purpose:

To characterize pre- and perioperative risk- and protective factors for treatment of wet age-related macular degeneration (wet AMD) treatment after cataract surgery.

Setting:

Register-based big data cohort study, based on data from the Swedish National Cataract- and the Swedish Macula Registers

Methods:

For all first-eye surgeries registered in the Swedish National Cataract register between 2010-2017, matching eyes were located in the Swedish Macula Register that had undergone treatment for wet AMD ≥1 year after the cataract procedure. Eyes with and without preoperative (dry) AMD were analyzed separately, and eyes not treated for AMD within the time period were used as controls. Pre- and perioperative risk- and protective factors for undergoing wet AMD treatment after routine cataract surgery were identified, with special attention to the use of blue-blocking IOL:s.

Results:

Among 451 805 + 121 771 first eye surgeries (with and without preoperative AMD, respectively) performed during 2010-01-01 – 2017-09-01, 911 + 744 eyes underwent treatment for wet AMD ≥1 year after the cataract procedure. Blue-blocking IOLs were equally represented in eyes subsequently treated for wet AMD and controls. High age and female gender were risk factors for undergoing wet AMD treatment.

Conclusions:

The risk of undergoing wet AMD treatment from 1-7 years after cataract surgery is not decreased by the use of blue-blocking IOL:s. High age and female gender are risk factors for subsequent AMD treatment.
