角膜地形图引导下超声乳化白内障手术的疗效分析

Efficacy Analysis of Corneal Topography Guided Phacoemulsification Cataract Surgery

目的分析角膜地形图引导下超声乳化白内障手术疗效。方法选取200例白内障患者,随机分为对照组(100例)与观察组(100例),对照组、观察组分别做常规90°透明角膜切口、角膜最大屈光度径线上透明角膜切口行超声乳化人工晶状体植入术,对比两组临床疗效。结果术后观察组裸眼视力高于对照组(P<0.05);观察组角膜散光度低于对照组(P<0.05)。结论角膜地形图引导下角膜最大屈光度径线上透明角膜切口行超声乳化人工晶状体植入术,可矫正散光度,利于患者视力恢复。

Objective To analyze the phacoemulsification for cataract surgery guided corneal topography. Methods 200 cases of cataract patients were chosen, randomly divided into for control group（100 cases） and observation group（100 cases）, control group, observation group were conventional 90°transparent corneal incision, corneal maximum flexion photometric diameter line transparent corneal incision ultrasonic phacoemulsification and intraocular lens implantation, the clinical efficacy was compared between the two groups. Results Postoperative observation group uncorrected visual acuity was higher than that of the control group（P〈0.05）, postoperative observation of corneal astigmatism of group is lower than that of control group（P〈0.05）. Conclusion Corneal topography guided under maximum corneal refractive degree diameter line transparent corneal incision phacoemulsification and intraocular lens implantation, can control the degree of astigmatism, which is conducive to the recovery of visual acuity.
