Anterior Chamber Depth Change Following Cataract Surgery in Pseudoexfoliation Syndrome; a Preliminary Study.

PURPOSE: To assess the pseudophakic anterior chamber depth (PP-ACD) or effective lens position (ELP) change after cataract surgery in patients with pseudoexfoliation syndrome (PEX). METHODS: Consecutive eyes with PEX and cataract underwent standard phacoemulsification and were implanted with single-piece acrylic posterior chamber intraocular lenses (IOLs). Eyes with severe PEX and with axial length (AL) greater than 24 mm or less than 22 mm were not included. Eyes with capsular complication or unstable bags that needed capsular tension ring insertion were excluded. The SRK-II formula was applied to calculate IOL power for postoperative emmetropia. PP-ACD or ELP was measured using anterior segment optical coherence tomography. Data obtained at one and six months post operation were evaluated during analysis. RESULTS: values = 0.15 and 0.2, respectively). CONCLUSION: After cataract surgery in eyes with PEX syndrome, a significant backward movement of the IOL occurs postoperatively in the first six months, which is associated with a concurrent small hyperopic shift.
