| 摘 要： | 应用计算机辅助的角膜地形图检测仪等手段对３２例４８只轻中度近视眼（－２．２５Ｄ至－５．００Ｄ）的放射状角膜切开术（ＲＫ）的疗效及安全性进行系统检测与分析，结果表明：四与八条切口、３．２５ｍｍ至３．５０ｍｍ光学区、取瞳孔缘最薄一点角膜厚度的切口深度的ＲＫ可安全有效地矫正轻中度近视眼的屈光不正。过多的角膜切口、过小的光迩区及角膜微穿孔措施可能不会对ＲＫ疗效带来有益的帮助。正确选择病例，合理设计手术方案

| Abstract: | omputer-assisted corneal topographic analysis was performed
on 48 eyes with low or moderate myopiaafter radial keratotomy(RK)by
using Topographic Modeling System(TMS-1).Low or moderate myopiawas
corrected successfully by 4 or 8 incision.3.25 to 3.50mm central
optical zone and blade depth was setequal to 100%of the thinness of
the four paracentral pachymetric readings. The more incision,the
smallerdiameter of central optical zone and corneal microperforation
appear to be not favourable in RK. |
