目的 观察角膜地形图引导白内障超声乳化术对角膜散光状态的影响.方法 对采用白内障超乳手术治疗的72例白内障患者进行观察,随机分为两组,34例角膜切口选择在角膜地形图垂直高曲率经线上,38例角膜切口选择在常规角膜12点左右方向,应用角膜地形图对手术前后角膜散光状态进行比较.结果根据角膜地形图曲率信息做角膜切口组散光度由术前的(1.11±0.36)D降低为术后3月的(0.96±0.32)D,常规12点左右方向角膜切口组散光度由术前的(1.08±0.54)D改变为术后3月的(1.36±0.43)D.根据角膜地形图曲率信息做角膜切口组术后1d和3月视力＞0.5者27只眼(78.6%)和30只眼(87.4%),要多于常规12点左右方向角膜切口组27只眼(72.5%)和31只眼(80.4%).结论 根据角膜地形图的曲率信息在手术切口的方位和角度进行选择,可以减轻术后角膜的散光状态,对视力的恢复有益.

Objective To study the impact on corneal astigmatism during phacoemulsification guided by corneal topography.Methods The cohort consisted of 72 patients treated by phacoemulsification and intraocular lens implantation.All patients were divided into two groups randomly.Of 34 eyes were made corneal incision on the steepest meridian,while 38 eyes chose the line on the superior position.Corneal topography was used to compare the corneal astigmatism before and after operation.Results The group which made incision using curvature message in corneal topography had an astigmatism change from(1.11±0.36)D before operation to(0.96±0.32)D after operation.And in this group the vision of 27 eyes were above 0.5(78.6%)first day after operation and 30(87.4%)eyes 3 months after operation.The group which made incision on the superior position had an astigmatism change from(1.08±0.54)D before operation to(1.36±0.43)D after operation.In this group the vision of 27 eyes were above 0.5(72.5%)first day after operation and 31 eyes(80.4%)3 months after operation.Conclusions Choosing corneal incision using curvature message in corneal topography could reduce corneal astigmatism postoperatively and get the best vision outcome.
