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.
