Vector analysis of surgically induced astigmatism was performed on several scleral and corneal tunnel incisions (6.0-mm W; 3.5- and 2.5-mm L scleral tunnel; 4.1-mm linear and 2.5-mm L corneal tunnel). The analysis revealed a mean astigmatism between 1.18 and 0.64 D, as compared to 0.35 D in a control group of nonoperated eyes. The best results were obtained with the scleral and corneal L-shaped incisions.
对多个巩膜和角膜隧道切口（6.0毫米宽；3.5毫米和2.5毫米长的巩膜隧道；4.1毫米直线形和2.5毫米长的角膜隧道）进行了手术诱导散光的矢量分析。分析显示，平均散光在1.18至0.64屈光度之间，相比之下，未手术眼睛的对照组为0.35屈光度。采用巩膜和角膜L形切口获得了最佳结果。
