Intraocular photocoagulation with the argon-krypton laser.

We have developed an intraocular laser coagulator using a low-loss single-fiber probe system connected to an argon-krypton laser. Coagulation can be accomplished at distances of 3 mm or greater from the retina, permitting easy control of lesion size, location, and intensity. The probe can be fired rapidly without overheating and can also be fired into air without damage to the tip.
