报道应用放射状角膜切开术（ｒａｄｉａｌｋｅｒａｔｏｔｏｍｙ，ＲＫ），矫正１８例近视性屈光参差。术前近视屈光度为－３．２５～－１１．００Ｄ，平均－６．５３Ｄ；屈光参差为－２．５０～－１１．００Ｄ，平均－４．９５Ｄ；裸眼视力为０．０２～０．１５，平均０．０８。术后半年检查，视力平均提高０．４６，屈光度平均下降－４．５７Ｄ，屈光参差平均下降－３．６０Ｄ。１４例术后恢复了双眼单视，６例立体视可达６０″。ＲＫ手术不仅能降低近视性屈光不正度数，提高裸眼视力，而且可减少或消除屈光参差，促进双眼单视功能的恢复。单侧或不对称近视的视力低下眼、矫正视力＞０．６者，可施行ＲＫ手术。屈光参差＜－９．００Ｄ者，ＲＫ术后可能恢复双眼单视；屈光参差＞－９．００Ｄ者，术后只能降低屈光参差，改善双眼单视条件。文中还介绍了近视性屈光参差术前检查、判断预后的方法及矫正的注意事项。
Reported the use of radial keratotomy (radialkeratotomy, RK), correction of 18 cases of myopic anisometropia. The preoperative myopic refraction was -3.25 ~ -11.00D, average -6.53D; anisometropia was -2.50 ~ -11.00D, average -4.95D; uncorrected visual acuity was 0.02-0. 15, an average of 0.08. Half a year postoperative examination, visual acuity increased by an average of 0.46, diopter decreased by an average of -4.57D, anisometropia decreased by an average of -3.60D. 14 cases of binocular surgery to restore the binocular vision, 6 cases of stereoscopic up to 60 ".RK surgery can not only reduce the myopia refractive errors, improve uncorrected visual acuity, and can reduce or eliminate anisometropia, and promote binocular vision function Recovery unilateral or asymmetric myopia, poor eyesight, corrected visual acuity> 0.6, can be performed RK surgery. Refractive error <-9.00D who RK surgery may restore binocular vision; anisometropia> 9.00D who can only reduce anisometropia after surgery to improve binocular vision conditions.The article also introduced the myopic anisometropia preoperative examination to determine the prognosis of the methods and corrective considerations.
