摘要
应用自制的角膜放射状切开术(radialkeratotomy,RK)电脑计算机软件,作为手术的预测标准,对术后已随访1年以上的77例(152只眼)、术前近视屈光度≤6.0DS的患者,进行了疗效统计,其中68%患者视力≥1.0。强调切口深度≥85%角膜厚度,才可获得远期疗效,因此精确测量用膜厚度至关重要。尽管RK疗效安全可靠,但仍存在其局限性。结合本国国情,提出了RK的适应症和禁忌症。
AbstractAmong myopic patients performed RK with oper-ative parameters stipulated by the authors'own com-puter software,77 cases(152 eyes) were followed upover 1 vear to find that 68 % of the eves withpreoperative myopia of≤-6.00DS attained visualacuity of 1.0 or better,and incision depths over 80% ofthe corneal thickness were conducive to long-termgood effects:hence accurate determination of thecorneal thickness was very important.In view of thelimitations of RK,the authors suggested indicationsand contraindications for the procedure.
