Abstract

Ocular dose-response relationships were experimentally determined by ophthalmoscopy and biomicroscopy for selected exposure conditions at the following laser wavelengths: 1.064 μ (neodymium), 1.318 μ and 1.338 μ (neodymium), 1.54 μ (erbium), and 2.06 μ (holmium). The ocular responses were observed in Rhesus monkey eyes. Corneal effects were produced at 1.3 μ, 1.54 μ, and 2.06 μ, and no retinal or lenticular effects were observed for the conditions tested. Both the dose required to produce a minimal corneal lesion and the depth of the response exhibit a wavelength dependence. The corneal damage thresholds were indicative of the relative absorption properties of the cornea. These results suggest that current permissible exposure limits for wavelengths in this region should be elevated to reflect the relative absorption properties of the ocular media. The 1.3 μ neodymium laser appears to offer an advantage in ocular safety, an important consideration in system applications.
