Histological studies on corneal damage produced by experimental lasers.

Abstract

A quantative and histological study was conducted of ocular damage in the rabbit eye from carbon dioxide (wave length 10.6μm) and WC (1.3μm) laser radiation.
A certain corneal opacity was found to occur following irradiation by a continuous wave carbon dioxide laser with energy doses of 0.1W/0.2mm²/5 sec, although shorter than 5 sec. irradiation caused corneal impact or opacity case by case. Tine serial study after irradiation revealed irregular alignment of the corneal collagen fiber.
Irradiation effect to the cornea by YAG laser was found to be moderate.
