摘要
目的评价小切口无缝合非超声乳化白内障摘除术对手术源性散光（SIA）和角膜内皮细胞的影响。方法对2010年1月至2011年8月就诊的白内障患者122例（139只眼）行小切口无缝合非超声乳化白内障摘除术，术前和术后1周、1个月及3个月测量角膜散光度，采用矢量分析法计算SIA值；并测量角膜中央区内皮细胞的密度、丢失率。结果术后1周、1个月角膜散光度与术前差异均有统计学意义（P〈O．05）；术后3个月角膜散光度与术前差异无统计学意义（P〉O．05）；术后3个月SIA值与术后1周、1个月差异有统计学意义（P〈0．05）。术后1周、1个月、3个月角膜内皮细胞密度与术前差异有统计学意义（P〈O．05）；术后1个月、3个月角膜内皮细胞丢失率无明显差异（P〉0．05）。结论小切口无缝线非超声乳化白内障摘除术所致SIA较低，对角膜内皮细胞损伤小。
Objective To evaluate surgically induced astigmatism and corneal endothelium after sutureless small incision extracapsular cataract extraction. Methods After sutureless small incision extracapsular cataract extraction, astigmatism of 122 cases （139 eyes） were measured pre-operatively, 1 week, 1 month and 3 months post-operatively. Surgically induced astigmatism was calculated using Vector Analysis method. Corneal endothelium density and loss rate were calculated by specular mi- croscopy. Results Astigmatism were significantly different between the groups before surgery and 1 week, 1 month after surgery （P 〈0.05）. There was no significantly different between the groups be- fore surgery and 3 months after surgery （P 〉0.05）. SIA were significantly different between the groups 3 months and 1 week, 1 month after surgery （P 〈0.05）. There was statistically significant dif- ference in corneal endothelial cell density between the groups before surgery and after surgery （P 〉 0.05）. The differences in corneal endothelium loss rate between 1 month and 3 months after surgery were not statistically significant （P 〉0.05）. Conclusions Sutureless small incision extracapsular cata- ract extraction cause low rates of astigmatism induced by surgery and endothelial cell loss.
