抗青光眼滤过性手术眼的后房型人工晶体植入

Posterior Chamber Intraocular Lens Implantation in Filtered Glaucoma Eyes

目的:为了探讨在已施行抗青光眼滤过手术的白内障眼进行白内障摘除和后房型人工晶体植入的手术方法以及手术对滤过泡的影响。方法:对抗青光眼滤过手术后白内障21只眼,避开滤过泡,选择颞下方角膜缘切口进行白内障囊外摘除及后房型人工晶体植入,同时对小而固定的瞳孔进行瞳孔括约肌切开与缝合术。结果:术后视力均有不同程度提高,76.19％术眼视力达0.5,术后平均眼压升高0.41kPa,功能滤过泡未见明显疤痕化。结论:对于抗青光眼滤过术后的白内障眼,进行通过颞下方角膜缘切口的白内障囊外摘除及人工晶体植入术,可提高术后视力,同时能较好地保持滤过泡的功能。眼科学报:1995;11:89—91。

Purpose : To investigate the method of cataract extraction with posterior chamber intraocular lens implantation in eyes that had undergone glaucoma filtering surgery and its effect on filtering bleb.Methods: Extracapsular cataract extraction with posterior chamber intraocular lens implantation was performed in 21 eyes with a preexisting filtration bleb, in which a lateral and inferior lateral limbal incison was selected, the pupil sphinc-tor was cut and the iris was sew for the small and fixed pupil. Results: the postoperative visual acuity of all patients was improved in different degrees, with 0. 5 or better in 76. 19% of the eyes. The postoperative IOP increased by 0. 41 kPa. The functional filtering bleb was not apparently cicatrized. Conclusions : Filtered glaucoma eyes with cataract can improve visual acuity and maintain the functional filtered bleb by extracapsular cataract extraction with posterior chamber intraocular lens implantation with lateral or inferior lateral limbal incision.
