放射状角膜切开术(RK)是一种有效的矫正近视的手术,尤其对于低中度近视,效果较为肯定。但对高度近视是否适宜手术,效果如何各家意见不一。本文报告了本院1992年10月至1993年7月100例≥-8D患者RK术后3个月结果,认为无近视退行性眼底改变或改变轻微的高度近视为RK的适应证。手术后平均屈光度减少6.9D,76.5%术后裸眼视力≥0.5,达到脱镜目的。眼球轴长并非影响手术效果的因素。周边切口加深意义不大。凡轴长超过27mm,近视有发展趋势者,宜在RK术前或同时行后巩膜加固术。
Radial corneal incision (RK) is an effective correction of myopia surgery, especially for low to moderate myopia, the effect is more certain. But for the high myopia is suitable for surgery, the effect of how different opinions. This article reports from October 1992 to July 1993 100 cases of ≥ 8D patients RK 3 months after the results, that no myopic degenerative changes or mild changes in mild myopia as RK indications. The average postoperative refractive power decreased 6.9D, 76.5% postoperative uncorrected visual acuity ≥ 0.5, to achieve the purpose of taking off the mirror. Eye shaft length is not a factor affecting the surgical results. Peripheral incision deepens little significance. Where the axial length of more than 27mm, myopia have development trends, should be performed before or after RK scleral buckling surgery.
