目的探讨同切口青光眼白内障联合手术对角膜源性散光的影响.方法对30例32只眼青光眼合并白内障患者行同切口白内障囊外摘除人工晶状体植入联合小梁切除手术.采用电脑验光曲率仪测量术前及术后3d、1周、1个月、3个月的角膜曲率的变化.结果术后3d散光度为(3.09±0.59)D,达最大,以顺规性散光为主,与术前相比,差异有统计学意义(P＜0.01).1周后散光度为(1.75±0.58)D仍以顺规性散光为主,与术前相比,差异有统计学意义(P＜0.01).3个月时散光度为(0.73±0.22)D,以逆规性散光为主,与术前相比,差异无统计学意义(P＞0.05).结论同切口青白联合手术术后早期可产生较大的散光,但角膜散光度可随时间的延长而逐渐减少,3个月时基本与术前相当.

Objective To evaluate postoperative corneal astigmatism following the same incisions of trabeculectomy combined with cataract extraction. Methods The combination of cataract surgery and implantation of intraocular lens with trabeculectomy through the same incision was performed on 32 eyes (30 glaucoma patients with coexisting cataract).The corneal astigmatism was evaluated by TOPCON keratometer before and after the operation at 3 days,1 week,1 month and 3 months.Results The changes of corneal astigmatism were statistically significant between 3 days and 1month (P ＜0.01).The corneal astigmatism was with-the-rule astigmatic at 3 days,1 week,1 month,but changed to against-the-rule astigmatic at 3 months with-the-rule astigmatic reached the maximum 3 days postoperatively (peak 3.09±0.59)D and decreased to (1.75±0.58)D 1 week postoperatively.The against-the-rule astigmatic was (0.73±0.22)D at 3 months postoperatively.Astigmatic changes was not found to be significant (P ＞0.05). Conclusions The combination of cataract surgery and implantation of intraocular lens with trabeculectomy through the same incision can cause the larger astigmatic at early stage,but corneal astigmatism in most of the cases decrease as time pass by.Regression is found at 3 months after surgery (P ＞0.05).
