Abstract
OBJECTIVE: To describe indications and outcomes of patients fitted with the EyePrintPRO therapeutic scleral lens. METHODS: A database search of patients fitted with the EyePrintPRO from 2014 to 2016. Fourteen eyes of 10 patients were reviewed retrospectively. Patient demographics, medical and ocular history, indications for fitting, duration of wear, symptoms, and best-corrected visual acuity (BCVA) were analyzed. RESULTS: Mean age at lens fitting was 49 years (range, 21-67 years). The average duration of wear was 12 months (range, 7-17 months). Indications for fitting included limbal stem cell deficiency, post-photorefractive keratectomy (PRK) decentred ablation, pellucid marginal degeneration, Stevens-Johnson syndrome, keratoconus, dry eye, neurotrophic keratitis, exposure keratitis from facial nerve paralysis, and post-radial keratotomy (RK) symptoms. Mean BCVA was 20/36 (range, 20/20-20/200). After the fitting, mean BCVA was 20/21 (range 20/10-20/60, p = 0.001). Nine patients reported resolution of their blurry vision, and all reported improvement of dry eye, eye redness, and pain symptoms. Six of 7 previous lens wearers reported significantly greater comfort with EyePrintPRO wear and the ability to wear the lens throughout the day; only 2 experienced fogging and needed to clean the lens after 4-6 hours of wear. CONCLUSIONS: A variety of indications for the EyePrintPRO scleral lens exist, and patients experience resolution of major symptoms. The ophthalmologist should be aware that therapeutic scleral lenses, including the EyePrintPRO, exist for patients for whom there is no surgical intervention or who want to delay or obviate the need for surgery.
