Abstract

Purpose
To investigate the endothelial cell loss after scleral fixation of posterior chamber intraocular lens (PCIOL) in low endothelial cell density (ECD) under 1,000 cells/mm². Methods: Retrospective review of 7 eyes were subjected to scleral fixation of PCIOL in low ECD. PCIOL subluxated eyes were operated with ab externo scleral fixation and aphakic eyes were operated with scleral fixation using foldable PCIOL. Endothelial cell loss, complications and postoperative outcomes were analyzed. Results: Mean LogMAR best corrected visual acuity improved from 0.44±0.24 to 0.25±0.19. Mean observed endothelial cell loss was 7.5±9.7% (56.0±86.1 cells/mm², 6.6±10.0% corrected for a natural endothelial cell loss of 0.6% a year). One eye had a intraoperative hyphema during the operation and 2 eyes had a postoperative localized bullous keratopathy. Conclusions: The scleral fixation with careful endothelial cell protection appeared to reduced endothelial cell loss and resulted visual improvement in low ECD.
