Indications for Wear, Visual Outcomes, and Complications of Custom Imprint 3D Scanned Scleral Contact Lens Use.

Abstract

To report indications for wear, visual outcomes, and complications of EyePrintPRO (EPP) scleral contact lens (SCL) use. A retrospective review identified all patients fitted with this device between December 2013 and March 2018. Baseline demographics, wear indication, and contact lens history were determined. Habitual-corrected visual acuity was measured at baseline and follow-up. Adverse wear symptoms and signs, reprinting, and device cessation were tracked. Ninety-five eyes from 69 patients were followed for a median of 12.1 months (interquartile range 4.4-19.6). Indications for wear included vision improvement and/or ocular surface stabilization in the setting of irregular corneal shape (n = 68 eyes, 72%), ocular surface disease (n = 17, 18%), exposure keratopathy (n = 7, 7%), neurotrophic keratitis (n = 5, 5%), and extracorneal topographical abnormalities preventing noncustom lens fitting such as glaucoma drainage devices (n = 8, 8%). Median habitual-corrected visual acuity improved from 0.67 to 0.08 (P = 0.0003). One-third of eyes (33.1%) developed adverse wear symptoms. Fifteen of 95 eyes (16%) developed adverse wear signs. Device cessation occurred in 10 eyes (10.5%) and reprinting occurred in 14 eyes (14.7%) unrelated to prior lens wear or indication (P = 0.67 and 0.15, respectively). In eyes that previously failed SCLs (n = 56), 12 eyes required reprinting and 49 eyes continued use. Indications for EPP wear include irregular corneal shape, ocular surface disease, and extracorneal topographic abnormalities. Visual acuity improves with the use of EPP. Clinicians and patients should be aware of potential adverse wear symptoms/signs and device cessation that may occur with EPP use. EPP is a viable salvage therapy in eyes that previously failed SCLs.
