Microscope–induced retinal phototoxicity after cataract surgery measured by optical coherence tomography (OCT)

Abstract

Abstract: : Purpose:To evaluate microscope–induced retinal phototoxicity after cataract surgery of short and long duration using optical coherence tomography (OCT) Methods:Prospective, consecutive case series of 40 patients undergoing phacoemulsification with posterior chamber intraocular lens implantation. OCT was obtained at preop, 1 day post–op, 1 week post–op, and 1 month post–op. The fellow eye served as the control. Results:Nerve fiber layer thickness, retinal thickness, and retinal pigment epithelial changes were correlated with duration of surgery, best–corrected visual acuity, and clinical examinations. Conclusions:OCT was able to demonstrate changes in the nerve fiber layer and macular area consistent with phototoxic damage.
