Photometric evaluation of YAG-induced polymethylmethacrylate damage in a keratoprosthesis

The use of the Nd:YAG laser in the photodiscission of retroprosthetic membranes represents a new clinical application. However, the potential adverse ophthalmic effects of YAG-induced PMMA damage to the keratoprosthesis are unknown. Consequently, precise photometric studies were conducted to evaluate image quality of the keratoprosthesis following YAG laser irradiation.
