目的观察分析青光眼白内障联合手术后患者角膜源性散光产生的原因。方法选取青光眼合并白内障患者45例45只眼进行青白联合手术,于术前、术后3 d、1周、1个月、3个月、6个月分析测量术眼角膜曲率及眼压。结果术后3 d角膜源性散光达到最大,主要是顺规性散光;术后3个月及6个月散光度与术前比较差异未见统计学意义(P>0.05),主要为逆规性散光。结论青光眼白内障联合手术后患者会出现短暂的较大度数的散光,术后3个月有恢复术前水平的趋势。
Objective To analyze the causes of corneal astigmatism in patients with glaucoma after cataract surgery. Methods Forty-five patients (45 eyes) with glaucoma and cataract were enrolled in this study. The corneal curvature and intraocular pressure (IOP) were measured before and 3 days, 1 week, 1 month, 3 months and 6 months after operation. Results The corneal astigmatism reached the maximum at 3 days after operation, and was mainly followed by astigmatism. There was no significant difference in astigmatism at 3 and 6 months after surgery (P> 0.05) Astigmatism. Conclusions Glaucoma and cataract surgery combined with postoperative short-term astigmatism in patients with a larger degree of astigmatism, 3 months after surgery to restore the preoperative level trends.
