    Abstract:
    PURPOSE: To evaluate the results of Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) scleral lens treatment on visual acuity and function in patients with ocular symptoms of chronic Stevens-Johnson syndrome (SJS). DESIGN: Retrospective interventional case series. METHODS: setting: Single multi-specialty institutional practice. study population: A chart review from July 2009 to July 2013 identified 19 patients with ocular symptoms from chronic SJS who were referred for PROSE fitting evaluation. Three patients deemed appropriate candidates were excluded because they were lost to follow-up during the fitting process. Only 1 eye was fitted in 4 patients because anatomic changes prohibited PROSE fitting in the fellow eye. Another patient chose to have PROSE fitting only in 1 eye. A total of 27 eyes of 16 patients who completed PROSE fitting were included in this study. intervention: PROSE scleral lens fitting. outcome measures: Visual acuity and visual function were assessed before and after PROSE fitting using Snellen acuity and Ocular Surface Disease Index (OSDI) survey. The OSDI survey is a validated questionnaire that assesses ocular surface disease in the context of vision-related function, ocular symptoms, and environmental triggers. RESULTS: Visual acuity improved from 0.43 ± 0.35 logMAR pre-PROSE to 0.14 ± 0.22 logMAR post-PROSE (P = .0007) in SJS patients. OSDI scores improved from 70.4 ± 19.0 pre-PROSE to 37.4 ± 23.2 post-PROSE (P = .0002) in the same cohort. CONCLUSION: The results of this study show that PROSE treatment is a viable option for improving visual acuity and function in SJS patients who failed conventional treatment.
