摘　　要：目的：了解和掌握准分子激光角膜表面切削术（PRK）后发生角膜混浊（Haze）情况并评价其相关影响因素。方法：将应用NIDEKEC－5000型扫描型准分子激光治疗的3896只眼发生2级以上Haze者做为分析对象并进行统计学处理。结果：术后两年随访发现：术后曾发生明显角膜混浊者31只眼（0.79％），平均等效球镜-7.34±1.14，散光1.52±1.35。96.77%为双眼同时发生，70.96%伴有屈光度的回退、对药物治疗敏感者51.61％，余需手术治疗。结论：PRK术后角膜混浊发生具有一定临床特点：多发生于年轻患者；以男性为多；以双眼同时发生居多;且大部分伴有屈光度回退并与术前屈光度和散光度成正相关，To understand the clinical status of the patient in relation with the possible risk factor after photore-fractive keratectomy. Methods: All the eyes with clinical sighficant hare were identified and analyzed stahstically. Results:The follow up for 2 yeare showed 31 eyes out of 3896 had clinical significant haze with a mean attempted correction (spheri-cal equivalent refraction) of-7. 34 ± 1. 14D, astigmatism 1. 52 ± 1. 35D; 96. 77% occurred in beil1 eyes and 70. 96% de-veloped refractive regression. No statistical djffrence between two eyes, but statistically greater in males. 51. 61 % were sen-sitive to the steroid. The rest need retreatment with PRK and PTK. Conclndon: The statistical analysis of subjective haze sug-gest that there is a specilic risk group for significant haaz: younger males, higher myopia, high astigmatism, etc. lt often occursin both eyes and is followed by refrctive regression.
