Abstract
PURPOSE: To analyze corneal endothelial cell damage after scleral fixation of intraocular lens (SFIOL) surgery. STUDY DESIGN: Retrospective study. METHODS: Medical records of consecutive eyes undergoing SFIOL surgery performed by a single surgeon were reviewed between January 2011 and June 2019. The patients were classified into three groups according to surgical methods: Group I, re-fixating the existing intraocular lens (IOL) or fixating a new IOL in an aphakic eye; Group II, removing the existing IOL and fixating a new IOL; and Group III, phacoemulsification and fixating a new IOL simultaneously. Preoperative and postoperative specular microscopy (SM) status were compared. Changes in SM were compared among the three groups. RESULTS: Ninety-four eyes were included. Thirty-four eyes in Group I, 39 in Group II, and 21 in Group III. The endothelial cell density (ECD) loss in Group I was 1.5%, less than the ECD loss of 14.3% (p < 0.001) in Group II and 15.4% (p = 0.005), in Group III. In no eye was there an ECD decrease to < 1000/mm2 following the surgical procedure. CONCLUSIONS: ECD loss was related to IOL removal or phacoemulsification rather than SFIOL surgery. SFIOL using the existing IOL should be considered preferential in eyes with low ECD and dislocated IOL.
