【摘要】：目的评估白内障超声乳化术中行陡峭子午线透明角膜切口对角膜前表面散光及角膜总散光的影响。方法回顾性分析2015年8~12月56例单纯白内障超声乳化术中行陡峭子午线的透明角膜切口的临床资料,分别在术前、术后1个月和3个月使用Pentacam眼前节分析系统进行检查,记录测量的角膜前表面散光和角膜总散光,并采用极坐标系评估在陡峭子午线方向行透明角膜切口对手术眼角膜散光的影响。结果所有患者手术及恢复顺利。与术前比较,术后1个月和3个月角膜前表面散光和角膜总散光AKP(+0)都有明显减少(P0.05),AKP(+45)无统计学意义(P0.05)。术后1个月与3个月相比角膜总散光和角膜前表面散光在AKP(+0)或AKP(+45)均无统计学差异(P0.05)。结论在术前角膜前表面散光的陡峭轴上行透明角膜切口可减少白内障手术后角膜总散光。
[Abstract]:Objective to evaluate the effect of steep radial transparent corneal incision during phacoemulsification on corneal anterior surface astigmatism and total corneal astigmatism. Methods 56 cases of cataract phacoemulsification from August to December 2015 were retrospectively analyzed. Clinical data of transparent corneal incision of meridian, The anterior corneal surface astigmatism and total corneal astigmatism were recorded by Pentacam anterior segment analysis system before, 1 and 3 months after operation, respectively. The effect of transparent corneal incision in the direction of steep meridian on corneal astigmatism was evaluated by polar coordinate system. At 1 and 3 months after operation, both anterior corneal astigmatism and total corneal astigmatism AKP0 were significantly reduced. There was no significant difference in AK-P45 between 1 month and 3 months after operation. Compared with 3 months after surgery, the total astigmatism and anterior surface astigmatism of the cornea were at AKP (0) or AKP (45). There was no statistical difference (P 0.05). Conclusion the steep axis of anterior corneal astigmatism can reduce the total corneal astigmatism after cataract surgery.
