Abstract
Purpose
This study aimed to investigate the clinical characteristics of patients with recurrent intraocular lens (IOL) dislocation after scleral-fixated sutured IOL implantation and evaluate the long-term outcomes of scleral re-fixation of IOL.
Methods
The medical records of patients who underwent surgery for IOL dislocation between January 2011 and January 2021 were reviewed. The study included 164 patients (male: 131, female: 33) (176 eyes). Patient demographics, preoperative, intraoperative and postoperative data, and the ocular and systemic conditions associated with IOL re-dislocation were analyzed.
Results
The study included 176 consecutive cases of scleral-fixated sutured IOL. Twenty-six eyes (14.8%) showed re-dislocation of IOL after the initial IOL scleral fixation and underwent reoperation (mean 75.5 ± 62.5 months after the first surgery); three (11.5%) of them required a third surgery. Younger adults (aged less than 40 years), and patients who underwent IOL scleral fixation in complicated cataract surgery or aphakic state had a higher risk of re-dislocation. Diabetes mellitus (DM) was the only statistically significantly higher risk factor in the re-dislocated group (p = 0.041). The complication rate with scleral re-fixation was higher than that in the non-re-dislocated group. No statistically significant differences were observed, except for vitreous hemorrhage (p = 0.024).
Conclusions
Caution should be exercised when performing sutured scleral fixation of IOL in younger patients, cases of complicated cataract surgery and aphakia, and patients with DM to prevent IOL re-dislocation. Scleral-fixated sutured IOL in eyes with recurrent IOL dislocation seems to be a safe and effective procedure with a relatively low complication rate.
