青光眼是致盲的主要病因之一。在目前医疗条件下,青光眼患者仍多为手术治疗,其中又以角膜上方滤过性手术为多。多数抗青光眼手术能促使晶体发生混浊,还能促进初发白内障的成熟。对做过青光眼滤过手术后发生白内障患者,应该在摘除白内障同时,保持原手术的滤过功能。十多年来,我们从角膜下缘做切口摘除白内障取得良好效果。 Glaucoma is one of the major causes of blindness. In the current medical conditions, glaucoma patients are still mostly surgical treatment, of which more than the top of the corneal filtration surgery. Most anti-glaucoma surgery can promote crystal opacity, but also to promote the maturation of primary cataracts. Glaucoma filter surgery done after cataract patients, should be removed in the cataract at the same time, maintain the filtration of the original surgery. For more than a decade, we performed cataract removal from the corneal margin to achieve good results.
