眼球的结构好似—光学系统,从前到后的屈光间质,即角膜、房水、晶体及玻璃体均透明而又有一定屈光指数。故激光问世以后,很快就被眼科界用来治疗眼底疾病。随着激光技术的发展,用于治疗眼科疾病的激光机增多,被治疗的病种亦更为广泛。近年来,短脉冲掺钕钇铝石榴石(Nd:YAG)激光系统,已引进至眼科显微手术。它不需在眼球上作切口,可直接进入眼内,对半透明或混浊的组织进行切 Eye structure is similar - the optical system, from front to back refractive interstitial cornea, aqueous humor, crystal and vitreous are transparent and have a certain refractive index. Therefore, after the laser was introduced, it was quickly used by ophthalmology to treat retinal diseases. With the development of laser technology, there are more and more laser machines used to treat ophthalmological diseases, and more are being treated. In recent years, the short-pulse Nd: YAG laser system has been introduced into ophthalmic microsurgery. It does not need to make an incision in the eye, can be directly into the eye, the translucent or cloudy tissue cutting
