青光眼和白内障在临床上常同时存在,手术式前者需切口引流,而后者需完全水密。在青光眼和白内障的联合手术方面,许多人进行了尝试。多数人认为慢性青光眼是人工晶体植入的相对禁忌症,青光眼病人的白内障术前应控制眼压,无晶体状态下的青光眼较难控制。囊外法摘除晶体联合小梁切除不会形成玻璃体阻滞于滤过口或粘附于切口,理论上比联合囊内摘除晶体术成功率高。1%透明质酸钠(Healon)的应用可预防巩膜或角膜虚脱,以及术后超滤过造成的浅前房,易于行人工晶体植入。
Glaucoma and cataracts often exist in clinical practice, the former surgical incision drainage, and the latter to be completely watertight. In the joint surgery of glaucoma and cataracts, many people have tried. Most people think that chronic glaucoma is the relative contraindication for intraocular lens implantation, glaucoma patients with cataract surgery should control intraocular pressure, glaucoma in the absence of crystal state more difficult to control. Extracapsular cataract extraction combined with trabeculectomy does not form a vitreous block in the filtration port or adhesion to the incision, in theory, than the combined intracapsular excision of the high success rate. The application of 1% sodium heparate prevents the sclera or corneal collapse, and the shallow anterior chamber caused by ultrafiltration, which is easy to implant with intraocular lens.
