Implantation of posterior chamber intraocular lens in cases without posterior capsular union

Abstract

Purpose: The purpose of this study was to compare the results of primary iris-fixated and scleral-fixated posterior chamber intraocular lens implantations in patients with in sufficient capsular support. Materials and Methods: A prospective analysis of patients who underwent primary sutured posterior chamber intraocular lens implantation secondary to insufficient posterior capsular support during cataract surgery was performed. Outcome measures werebest corrected visual acuity, change in visual acuity and complications. Results: In this study, 13 patients (30.2\%) underwent iris-fixated and 30 patients (69.8\%) scleral-fixated posterior chamber intraocular lens implantations. The visual acuity improved by at least one Snellen line or remained unchanged in 11 patients (84.6\%) in the iris-fixated group and in 25 patients (83.3\%) in the scleral-fixated group. Patients with best corrected visual acuity of 0.5 or higher were 30.8\% (n = 4) in the iris-fixated group and 50\% (n = 15) in scleral-fixated group postoperatively. Conclusion: Both primary iris-fixated and scleral-fixated posterior chamber intraocular lens implantations can provide favorable visual outcomes. The points to underline for the fixation of the sutured posterior chamber intraocular lens arethe preoperative condition of the patient's eye, the situation of the area to be fixed, the type of lens and the preference of the surgeon.
