Visual outcome of scleral fixation of posterior chamber intraocular lens in eyes with inadequate capsular support
Abstract
Objective: To evaluate visual outcome and complications of scleral fixation of posterior chamber intraocular lens (SF-IOL) in eyes with inadequate capsular support.
Methodology: This is a prospective case series which consists of eighteen eyes of 13 patients. These were divided into group A having traumatic subluxation of lens or inadequate posterior capsular support and group B with idiopathic, familial and syndromic ectopia lentis having zonular weakness more than 180º. Lensectomy and SF-IOL was performed. Best corrected visual acuity (BCVA), intraocular pressure (IOP), intraocular lens (IOL) positioning, anterior and posterior segment examination was performed on every follow up visit.
Results: Mean age was 15.05 ± 8.99 years. Mean follow up was 18.88 months ± 15.07. Mean preoperative logMAR BCVA in 18 eyes was 0.93 ± 0.76 and mean postoperative log MAR BCVA was 0.41± 0.24(p=0.01). Mean postoperative logMAR BCVA in group A was 0.27±0.27 and group B was 0.48 ± 0.20. Twelve eyes (66.7%) did not show complications. Fourteen eyes (77.8%) did not require second surgery after SF-IOL.
Conclusion: SF-IOL is a safe procedure in eyes with inadequate posterior capsular support and ectopia lentis with more than 180º of zonular weakness.
