Abstract

Corneal endothelial damages following Nd: YAG laser application were evaluated rabbits. The first group underwent anterior capsulotomy, while the second group received laser applications at the corneal center and anterior capsule. The rabbits were evaluated with the intraocular pressure, the corneal endothelial cell number, the thickness of the corneal center, and the morphologic change of the cornea, before laser application and at postaplication 1 day, 7 day, and 14 day. But the endothelium was damaged when laser shots were applied at the cornea center and anterior caps ulotomy. In ophthalmologic procedure with Q-switched Nd:YAG laser, the minimal effective poser should be selected, the laser beam should be applicated on extremely fine focus and contact lens should be used to minimize the corneal endothelial injury.
