2Associate Prof. MD, Ophthalmogy Department of Kartal Dr. Lütfi Kırdar Training and Research Hospital, Istanbul, Turkey DOI : 10.37844/glauc.cat.2021.16.5 Purpose: To evaluate indications and visual outcomes of intraocular lens (IOL) exchange to understand recent changes in this surgery.
Materials and Methods: One hund red twenty seven eyes of 122 patients that underwent surgery to exchange or reposition the IOL between 2009 and 2019 were included in the study. The IOL exchange indications, time between surgeries, treatment parameters, intraoperative and postoperative complications, and pre- and postoperative best-corrected visual acuity (BCVA) were recorded and analyzed. Rates of IOL exchange indications were compared according to IOL exchange 5 year period.
Results: The most frequent IOL exchange indication were IOL dislocation (69 eyes, 54.3%), corneal decompensation (23 eyes, 18.1%), patient dissatisfaction (17 eyes, 13.3%), incorrect lens power (12 eyes, 9.4%). The mean BCVA was improved from 0.72±1.13 Log MAR to 0.23±0.53 Log MAR after the surgery (p? 0.01). The most common indication in both duration time was IOL dislocation. But the second frequent indication in the first time period was corneal decompensation while the second frequent indication in the second time period was IOL dissatisfaction.
Conclusion: It was noteworthy that IOL dissatisfaction has increased steadily recently, while IOL dislocation was the most common in the entire study process.
