Abstract

PURPOSE:

To compare intraocular pressure (IOP) elevation and graft rejection with loteprednol etabonate 0.5% gel and prednisolone acetate 1% solution after Descemet membrane endothelial keratoplasty (DMEK).

METHODS:

In this prospective, evaluator-masked trial, 167 patients were randomized to loteprednol or prednisolone in a 1:1 ratio 1 month after DMEK; 66 fellow eyes were enrolled and assigned to the opposite treatment. Dosing was 4 times daily for 2 months, thrice daily for 1 month, twice daily for 1 month, and once daily for 7 months. The main outcomes were IOP elevation (defined as IOP ≥ 24 mm Hg or an increase of ≥10 mm Hg over the baseline preoperative level) and immunologic rejection episodes, assessed by Kaplan-Meier survival analysis and proportional hazards modeling.

RESULTS:

A total of 233 eyes were assigned to treatment. Loteprednol etabonate 0.5% gel and prednisolone acetate 1% solution were equally effective in preventing immunologic rejection episodes; none (0%) occurred with either treatment (P = 1). IOP elevation was twice as likely in the prednisolone-treated eyes (relative risk = 2.3, 95% confidence interval: 1.2-4.5, P = 0.016). The proportion with IOP elevation was 25% in prednisolone-treated eyes versus 11% in loteprednol-treated eyes (P = 0.013). In 66 subjects with fellow eyes assigned to opposite treatments, an IOP increase of ≥10 mm Hg was significantly more likely in the prednisolone-treated eye (P = 0.031).

CONCLUSIONS:

Loteprednol etabonate 0.5% gel was as effective as prednisolone acetate 1% solution in preventing immunologic graft rejection episodes after DMEK and was significantly less likely to cause IOP elevation.Clinical Trial Registration-URL: http://www.clinicaltrials.gov. Unique identifier: NCT01853696.
