对曾行青光眼滤过术的患者再次行白内障手术时 ,为保护滤过泡 ,手术切口一般选在角膜缘内 ,这样势必会造成术后较大的散光 ,固此既保护滤过泡 ,术后又不会出现较大的散光是一个值得研究的问题。笔者采用角膜缘内 6mm切口行囊袋内白内障摘除联合后房型人工晶体植入 (囊袋内 )的 For glaucoma filtering surgery in patients undergoing cataract surgery again, in order to protect the filtration bleb, the surgical incision is generally selected within the limbal margin, this will inevitably lead to greater postoperative astigmatism, which not only protect the bleb, surgery And then there will be no greater astigmatism is a study worthy of the question. I use the limbal corneal incision 6mm incision cataract extraction combined with posterior chamber intraocular lens implantation (capsular bag)
