Outcomes of Secondary Intraocular Lens Implantation and Descemet Stripping Endothelial Keratoplasty-Comparing Staged Versus Combined Surgical Approach

Abstract

Purpose: The aim of this study was to compare the outcomes of staged versus combined surgical approach for secondary intraocular lens (IOL) implantation and Descemet stripping endothelial keratoplasty (DSEK).

Methods: This is a retrospective review of 124 eyes from 124 patients who underwent either staged or combined secondary IOL implantation in addition to DSEK over a 5-year period at 2 academic tertiary referral centers, between January 1, 2014, and October 1, 2019. Corrected distance visual acuity (CDVA), presence of graft detachment, primary graft failure (PGF), and cystoid macular edema were documented and analyzed.

Results: The CDVA for the 1- to 2- month follow-up period was significantly better in the staged group compared with the combined group ( P = 0.011). By the postoperative 6- to 9-month follow-up period, there was no significant difference in the CDVA between the groups ( P = 0.591). There was no significant difference in the incidence of PGF or graft detachment between the 2 groups ( P > 0.05). In addition, there was no significant difference in the CDVA or rate of postoperative complications between the different methods of IOL fixation.

Conclusions: The short-term visual outcomes were significantly better in eyes that underwent staged secondary IOL implantation and DSEK versus the combined surgical approach, although the difference was no longer present at 6 to 9 months. There was no difference in the rate of PGF or graft detachment between the 2 groups.
