• Clinical research utilizing the yellow, orange, and red wavelengths of the liquid organic dye laser has demonstrated that this laser may be successfully used for photocoagulation of certain ophthalmic defects. The advantage of the dye laser as a photocoagulation source is its capability to produce monochromatic wavelengths at relatively high output powers through a large range of the visible spectrum. Therefore, a target tissue can be coagulated with minimal transmittal of laser energy through the ocular media, by the selection of a wavelength that would be most highly absorbed by that tissue. The dye laser, as a system that permits transspectral photocoagulation, should prove valuable in the treatment of ocular disease.
