Abstract

In Argon-Laser treatment of the retina the problem occurs that in case of large- area irradiation, for instance when coagulating neovascular areas, the laser energy is not applied uniformly over the coagulation area due to the Gaussian beam intensity distribution. This may cause heavy damages to the tissue and jeopardize or even prevent its regeneration. Furthermore the anterior eye segments, particularly the cornea may be damaged by the high beam energy and the flat cone angle which is needed to obtain a large coagulation spot.
