近年来,由于眼科器械的更新和手术技术的改进,尤其是在眼科显微镜下白内障摘除术是使患者复明的主要办法。又由于显微手术的应用和后房型人工晶体植入术的发展,白内障手术出现由囊内向囊外的传变。白内障囊外术保留晶体后囊,可使眼球获得较大的稳定性,并能减少眼内震荡、视网膜
In recent years, due to the renewal of ophthalmic instruments and the improvement of surgical techniques, especially in ophthalmic microscopy, cataract extraction is the main method for patients to be reconstructed. Also due to the application of microsurgery and posterior chamber intraocular lens implantation, cataract surgery occurs from the sac to the extracapsular transmission. Cataract extracapsular preservation of the posterior capsule, the eye can get greater stability, and can reduce intraocular shock, the retina
