1960年第一个激光发生器的研制成功,使应用高亮度、高准直性和高相干性的单色光成为可能。现在激光光凝疗法已广泛应用于黄斑变性和糖尿病性视网膜病变,激光虹膜切除术在很大程度上取代了传统的手术疗法,激光小梁成形术常可有效地控制开角型青光眼,从而避免了有一定风险的滤过性手术。最近正采用短脉冲钕钇铝石榴石激光(Nd-YAG)有效地治疗各种眼科疾病,如继发性白内障、玻璃体索条等。并为改进现有的眼内组织激
The successful development of the first laser generator in 1960 made it possible to apply monochromatic light with high brightness, high collimation and high coherence. Now laser photocoagulation has been widely used in macular degeneration and diabetic retinopathy, laser iridotomy has largely replaced the traditional surgical treatment, trabeculoplasty can often be effective in controlling open-angle glaucoma, thus avoiding There is a certain risk of filtration surgery. Recently, short-pulse neodymium-yttrium aluminum garnet laser (Nd-YAG) is being used to effectively treat various ophthalmic diseases such as secondary cataract and vitreous cord. And to improve the existing intraocular tissue irritation
