通过降低角膜屈光力来矫正近视的手术——角膜周边部放射状切痕术,正在逐渐引起眼科界更大的注意,作者从69年至77年共进行这种手术231例(426眼),其中主要是轻、中度近视,仅8例近视为12.0D～16.0D。手术时,用0.5％地卡因滴眼,角巩膜缘周围结膜下注射1％普鲁卡因。在角膜上以中心定位器标出瞳孔区,然后从瞳孔区外缘开始直到角巩膜缘为止用晶体囊刀或剃刀片作放射状切口 By reducing corneal refractive power to correct myopia surgery - corneal peripheral radial incision, is gradually causing more attention in the ophthalmology, the author from 69 to 77 years of operations were carried out in 231 cases (426 eyes), of which the main Is mild to moderate myopia, only 8 cases of myopia as 12.0D ~ 16.0D. At the time of surgery, 1% procaine was injected subconjunctivally around the scleral limbus with 0.5% tetracaine. In the cornea to the central locator marked pupil area, and then from the outer edge of the pupil area until the angle until the limbus with a crystal knife or razor blade for radial incision
