Abstract
Purpose: To investigate the indications and outcomes of intraocular lens (IOL) exchange surgery in a cohort of pseudophakic Iranian patients.
Patients and Methods: This retrospective cross-sectional study evaluated the indications and outcome of IOL exchange surgery among pseudophakic Iranian patients. The study included adult patients (age > 18 years) who underwent IOL exchange surgery at Torfeh and Imam Hussein Hospitals, Tehran, Iran, from April 2020 to April 2021. Post-surgical metrics such as best-corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and intraocular pressure (IOP) were extracted from the medical files.
Results: The study encompassed 36 eyes from 36 patients. The mean age of the patients was 47.3 ± 11.1 years. The most common indication for IOL exchange was lens dislocation, observed in 26 patients (72.2 %), followed by IOL-induced uveitis-glaucoma-hyphema syndrome in 6 patients (16.7 %), unexpected IOL power ("IOL surprise") in 3 patients (8.3 %), and calcified IOL in 1 patient (2.8 %). There was a significant postoperative improvement in the mean UCVA and BCVA (Pvalue < 0.001 for both) compared to pre-surgical readings. The mean IOP before IOL exchange was 16.30 ± 3.89 mmHg, which decreased to 15.05 ± 4.32 mmHg after lens exchange; however, this improvement was not statistically significant (P = 0.42).
Conclusion: Consistent with prior studies, the most prevalent reason for IOL exchange among our patients was IOL dislocation. Our study also indicates an improvement in visual acuity post-surgery, in line with other research findings.
