To investigate the method of cataract extraction in eyes that had undergone glaucoma filtering surgery and its effects on filtering bleb.
Phacoemulsification with posterior chamber intraocular lens implantation was performed on 262 eyes with a preexisting filtration bleb, in which at the temporal clear cornea a lateral or inferior lateral limbal incision was selected, the pupil sphincter was cut and the iris was sewed for the small and fixed pupil.
The postoperative visual acuity of all patients improved in different degrees, with >or= 0.5 in 74.0% in the first month. The postoperative IOP increased by 3.08 mmHg. The functional filtering bleb was not apparently cicatrized.
Glaucomatous eyes with cataract after filtering operation can rehabilitate their visual acuity and maintain the functional filtering bleb by phacoemulsification with foldable intraocular lens implantation through a temporal clear corneal incision or lateral scleral pocket incision. Theoretically, the effect of a transparent corneal incision on filtering bleb is less than that of a scleral pocket incision.
探讨青光眼滤过术后白内障的摘出方法及其对滤过泡的影响。
对262只已有滤过泡的眼睛行超声乳化白内障吸除联合后房型人工晶状体植入术，其中颞侧透明角膜处选择侧方或颞下侧角膜缘切口，对于小瞳孔且固定的情况，切断瞳孔括约肌并缝合虹膜。
所有患者术后视力均有不同程度提高，术后1个月时视力≥0.5者占74.0%。术后眼压升高3.08 mmHg。功能性滤过泡无明显瘢痕化。
青光眼滤过术后合并白内障的患眼可通过颞侧透明角膜切口或巩膜侧方隧道切口行超声乳化白内障吸除联合折叠式人工晶状体植入术恢复视力并维持功能性滤过泡。理论上，透明角膜切口对滤过泡的影响小于巩膜隧道切口。
