PURPOSE
To evaluate the effectiveness of limbal relaxing incisions (LRIs) for correcting corneal astigmatism during cataract surgery.
SETTING
Cullen Eye Institute, Houston, Texas, USA.
METHODS
In 12 eyes of 11 patients, cataract surgery was combined with LRIs. The LRIs were made according to a modified Gills nomogram and were based on preoperative corneal astigmatism determined with standard keratometry and computerized videokeratography (EyeSys Corneal Analysis System Version 3.2).
RESULTS
The mean preoperative keratometric cylinder was 2.46 +/- 0.81 diopters (D). At 1 month postoperatively, mean arithmetic reduction in keratometric cylinder was 1.12 +/- 0.74 D, and the with-the-wound (WTW) change (calculated by Holladay, Cravy, Koch vector analysis formula) was -0.70 +/- 0.44. From 1 day to 1 month postoperatively, there was 0.55 D of WTW regression with minimal change in the mean cylindrical axis. There were no overcorrections.
CONCLUSION
Limbal relaxing incisions are a practical, simple, and forgiving approach to the correction of astigmatism during cataract surgery.
目的
评估在白内障手术中角膜缘松解切口（LRIs）矫正角膜散光的有效性。
地点
美国得克萨斯州休斯顿市卡伦眼科研究所。
方法
对11例患者的12只眼进行白内障手术并联合角膜缘松解切口。角膜缘松解切口根据改良的吉尔斯列线图制作，基于术前使用标准角膜曲率计和计算机化视频角膜地形图（EyeSys角膜分析系统3.2版）测定的角膜散光情况。
结果
术前平均角膜曲率计测量的散光度数为2.46±0.81屈光度（D）。术后1个月，角膜曲率计测量的散光度数平均算术降低1.12±0.74 D，伤口相关（WTW）变化（通过霍拉迪、克拉维、科赫矢量分析公式计算）为-0.70±0.44。术后1天至1个月，WTW回退0.55 D，平均散光轴变化极小。无过矫情况。
结论
角膜缘松解切口是白内障手术中矫正散光的一种实用、简单且容错性好的方法。
