Abstract
Experimental and clinical studies on the Nd-YAG laser were carried out. The CW Nd-YAG laser and the pulse train Nd-YAG laser have thermal effects on ocular tissues, so that retinal and choroidal photocoagulation is possible with different coagulation characteristics, as compared with the argon laser. The Nd-YAG laser coagulate deeper layers of the fundus without much damage to the retinal nerve fiber layer. Thermal effects are also applicable for laser iridotomy. The Q-switched Nd-YAG laser has the effect of photodisruption, which is useful for membrane cutting. Opaque pupillary membrane dissection and laser iridotomy were successfully performed without any serious complications.
