一、人工晶体植入的趋势 1949年11月英国Ridley首次在白内障摘除术后植入后房型人工晶体。由于白内障摘除技术的熟练,器械的精良,手术显微镜的广泛应用,新型人工晶体制造工艺的改进,自1975年至今发展到第四代人工晶体,使白内障术后植入人工晶体安全且恢复视力。避免了戴高度眼镜,减少物像放大率,且有接近眼球结点等优点。美国1979年前的30年中每年约有8万例人工晶体植入,80年代初每年已超过50万例,日本百懒皓曾做4561例,视力达1.0约90％。我国1980年人工晶体协作组出版了人工晶体专辑,临床应用和制造技术已在各大中城市开展与研究。但有些眼科专家认为眼内植
First, the trend of intraocular lens implantation In November 1949, Ridley, England for the first time after implantation in cataract extraction posterior chamber intraocular lens. Due to the excellent technique of cataract extraction, the excellent equipment, the extensive application of surgical microscope, the improvement of the manufacturing process of new IOLs, the fourth generation IOLs have been developed since 1975, which enable the intraocular lens implantation and cataract recovery after cataract surgery. Avoid wearing a high degree of glasses to reduce the image magnification, and close to the eye node and so on. Approximately 80,000 artificial implants are implanted in the United States each year in the 30 years prior to 1979, with more than 500,000 impaired annually in the early 1980s. 4561 were made in Japan, and their visual acuity reached about 90%. China’s 1980 IOL Group published an album of artificial crystals, clinical applications and manufacturing technology has been carried out in major cities and research. However, some ophthalmologists believe that intraocular implantation
