透明质酸钠是自雄鸡的鸡冠组织制取而来,现在可以人工合成。它是一种没有抗原性的单纯高分子物质,富有弹性和高度粘性,无明显毒性及致炎性。目前透明质酸钠已被广泛用于眼内人工晶体置入术、白内障囊内或囊外摘出术、青光眼手术、角膜移植术、眼球穿通伤修补术、视网膜脱离复位术以及玻璃体置换术等。它为这些手术提供了方便和安全,并取得了满意效果。因此,不少眼科学者认为透明质酸钠是眼前段手术中的一种理想辅助物,并认为这是近十年来眼科手术中的重大进展之一。一、透明质酸钠在白内障手术中的应用
Sodium hyaluronate is derived from chicken cocks and can now be artificially synthesized. It is a non-antigenic pure polymer, flexible and highly viscous, non-toxic and inflammatory. At present, sodium hyaluronate has been widely used in intraocular lens implantation, cataract extracapsular or extracapsular extraction, glaucoma surgery, corneal transplantation, penetrating eye injury repair, retinal detachment and vitrectomy and so on. It provides convenience and safety for these procedures and achieves satisfactory results. Therefore, many ophthalmologists think that sodium hyaluronate is an ideal auxiliary in the anterior segment surgery, and this is one of the major advances in ophthalmic surgery in the past decade. First, the application of sodium hyaluronate in cataract surgery
