应用角膜内皮显微镜研究已确定,角膜内皮细胞是不能再生的,内皮细胞的缺损区只能通过其他内皮细胞的面积增大和滑行来填补。人工晶体植入术一个最重要的步骤,就是必须通过一定的方法来保护内皮。前房注射空气虽然取得一些效果,因空气不易固定在前房,往往在关键时刻溢出而达不到目的。Healon是近年来继α-糜蛋白酶(α-chymotrypsin)之后,在白内障手术中应用得最成功的物质。但它制造困难,价格昂贵,有时可引起术后高眼压,且不易稀释,以致手术结束时不易完全被冲出,这些缺点限制 Corneal endothelial microscopy studies have identified corneal endothelial cells that can not regenerate, and endothelial cell defects can only be filled by increasing the area and gliding of other endothelial cells. One of the most important steps in IOL implantation is the protection of the endothelium by certain methods. Although the injection of air into the anterior chamber achieved some results, the air is not easily fixed in the anterior chamber and often fails to reach the target at the critical moment. Healon is the most successful material for cataract surgery after α-chymotrypsin in recent years. But it is difficult to manufacture, expensive, and sometimes can cause postoperative intraocular hypertension, and difficult to dilute, so that the end of the surgery is not easy to be completely washed out, these shortcomings limit
