Electron microscopic appearances of human corneal endothelium following Nd:YAG laser iridotomy.

We looked at the electron microscopic appearances of the corneal endothelium following neodymium:YAG (Nd:YAG) laser iridotomy in a patient with a shallow anterior chamber. An area of denuded endothelial cells approximately 500 microns in diameter was produced when no contact lens was used. The area of cell loss was reduced by approximately 50% when an Abraham YAG goniolens was used. We conclude that the use of a positive plus contact lens can help minimize cell loss following Nd:YAG laser iridotomy.
