用低温冷冻方法进行白内障囊内摘出术,是Krwawicz(1961)开始使用。因明显地提高囊内摘出术的成功率,扩大了囊内摘出术的适应症,因此很快得到重视,并在此基础上纷纷有所改进。我国各地自1964年根据他提出的方法或在此法的基础上加以改进开始开展白内障冷冻摘出术。十七年来除了使用干冰为冷却剂外,国内还用了氟利昂,高压氧,泡沫二氧化碳,液氧,液氮,液氢,液氦,及半导体冷冻器等。根据我院实际情况,因太钢动力厂制氧工段生产液氧、液氮、液气(液态空气)等,故自1976年与
Cryosurgery for intracapsular cataract extraction has been used by Krwawicz (1961). Due to the significant increase in the rate of success of intracapsular removal surgery, enlarging the indications of intracapsular removal surgery, it quickly gained attention, and on the basis of these have been improved. Since 1964, our country has started to carry out the cataract cryoablation based on the method proposed by him or on the basis of this law. Seventeen years in addition to using dry ice as a coolant, the country also used Freon, hyperbaric oxygen, foam carbon dioxide, liquid oxygen, liquid nitrogen, liquid hydrogen, liquid helium, and semiconductor freezers. According to the actual situation in our hospital, due to the production of oxygen, liquid nitrogen, liquid gas (liquid air) and other oxygen production section of Taigang Power Plant, so since 1976
