| Abstract |
The ocular dose-response relation, on the cornea of the eyes of Rhesus monkeys, were determined after exposure to erbium and holmium lasers under various conditions. The effective dose for 0.5 probability of producing a biomicroscopically visible corneal lesion (ED50), determined for single corneal exposures were 9.6, 2.9 and 5.2J/cm2 under conditions of 1.54µm wave length, 930µsec exposure, 1.0mm irradiance diameter; 2.06µm, 100µsec, 1.8mm; and 2.06µm, 42nsec, 0.32mm, respectively. The depth and diameter of corneal lesions were both dose and wavelength dependent. The wavelength dependence of the dose required to produce a lesion is indicative of the relative absorption properties of the cornea. Exposure limits should reflect the relative absorption properties of the ocular media. |
