Abstract
PURPOSE
To evaluate the appropriate correction of predicted intraocular lens (IOL) power when sulcus implantation due to posterior capsular rupture was performed and to compare the anterior chamber angle of sulcus-implanted eyes with in-the-bag implanted eyes using anterior segment optical coherence tomography (Visante OCT). METHODS: Fifty-two eyes of 52 patients who had IOL implantation in the sulcus due to posterior capsular rupture during cataract surgery were retrospectively reviewed. A 0.5 lower diopter IOL than predicted IOL power using SRK-T formula was chosen. The difference between the predicted refractive error and the spherical equivalence at the 3-month time-point after sulcus implantation were evaluated. Among 52 patients, 16 patients whose fellow eye had an in-the-bag IOL implantation underwent Visante OCT and the anterior angle of affected eyes and normal fellow eyes were compared. RESULTS: The difference between the predicted refractive error using SRK-T formula and the spherical equivalence after sulcus implantation was a myopic shift of 0.597 +/- 0.879 diopter. The mean iridocorneal angles, angle opening distance (AOD), trabecular iris surface area (TISA) at 500 um and 750 um for both nasal and temporal sides in sulcus implantation were all significantly lower than in-the-bag implantation. CONCLUSIONS: A choice of a 0.5 lower diopter power IOL than the power for in-the-bag implantation may be considered because of greater myopic shift than predicted refractive error when sulcus implantation due to posterior rupture is performed. Anterior chamber angle in sulcus IOL implantation was shallower than in-the-bag IOL implantation.
