UnlabelledWe report 4 cases of acute corneal edema with subsequent thinning and hyperopic shift following routine selective laser trabeculoplasty (SLT) for the treatment of primary open-angle glaucoma. Four women from 3 clinical sites developed acute corneal edema and haze within 2 days of uneventful SLT. In the following weeks to months, all treated corneas thinned to below pre-procedure thicknesses with resultant hyperopic shifts of nearly 2.0 diopters (D) to greater than 6.0 D. All eyes were moderately to highly myopic prior to SLT (spherical equivalent from -5.00 to -12.5 D). The corrected distance visual acuity 6 to 11 months after SLT was within 2 Snellen lines of the pre-procedure acuity in all patients; 2 patients required contact lenses. Corneal edema with subsequent corneal thinning and resultant hyperopic shift is an uncommon but possibly underrecognized complication of SLT, the etiology of which remains unknown but may be associated with moderate to high myopia.Financial DisclosureNo author has a financial or proprietary interest in any material or method mentioned.Copyright © 2014 ASCRS and ESCRS.
