摘要
目的:探讨准分子激光角膜屈光术治疗屈光不正术后5年的远期疗效。方法:选取于我院行准分子激光屈光性角膜手术(Photorefractive keratectomy,PRK)治疗的屈光不正患者90例,按术前等值球镜度分为A、B、C三组,三组均行PRK术治疗,术后随访5年,观察三组视力、屈光度、视觉质量的情况。结果:三组5年随访,A、B、C组裸眼视力≥0.5分别为100%、100%、93.3%;三组均未出现1级以上角膜上皮下雾状浑浊(Haze)、继发性圆锥角膜、角膜扩张和视网膜脱离。结论:PRK治疗屈光不正眼疗效确切,其预测性及稳定性与屈光不正度数呈负相关,且远期疗效良好。
Objective: To investigate the curative effects of photo refractive keratectomy (PRK) on ametropy in five years after the surgery. Methods: According to the severity of preoperative parity ball lens, a total of 90 cases with ametropy admitted in our hospital during Jan 2005 to Feb 2006 were enrolled and divided into group A, B and C. All patients underwent PRK, and 5 years follow-up were conducted to record their eyesight, diopter and visual quality. Results: According to the follow-up data, 100%, 100% and 93.3 patients of group A, B and C showed naked eye visual acuity above 0.5. No corneal epithelium under fog turbidity (Haze) severer than one grade, corneal ectasia or retinal detachment occurred in these patients. Conclusion: PRK treatment shows definite good long-term effects on ametropy, and its predicta- bility and stability negatively correlated with ametropy severity.
