Laser in situ keratomileusis (LASIK) is the procedure of choice for high myopia. We present a study of 85 eyes undergoing LASIK for myopia between -1.00 and -3.50 diopters (D) and assess the safety and efficacy of the procedure for treatment of low myopia.
Eighty-five eyes of 47 patients with a mean age of 29 years, (range, 18 to 56 yrs) underwent LASIK using the Chiron microkeratome and the Nidek EC-5000 excimer laser. Mean preoperative myopia was -2.09 D and mean astigmatism was 0.86 D. All other ocular pathology was ruled out before surgery. Mean follow-up was 48 days (range, 1 day to 13 mo).
Uncorrected visual acuity of 6/9 or better at 1 week was achieved in 44 eyes (52%); at 1 month in 68 eyes (80%); and at 6 months in 70 eyes (93%). Pain score was minimal with the majority of patients having no postoperative pain. One eye suffered a serious postoperative complication of corneal abscess which resolved with treatment, but left a corneal scar and visual acuity of 6/60.
LASIK is a safe and effective procedure for low amounts of myopia; it also provides early visual rehabilitation and markedly reduced pain and discomfort to patients undergoing refractive surgery.
准分子原位角膜磨镶术（LASIK）是高度近视的首选手术方法。我们对85只近视度数在-1.00至-3.50屈光度（D）之间接受LASIK手术的眼睛进行了一项研究，并评估了该手术治疗低度近视的安全性和有效性。
47例平均年龄29岁（范围18至56岁）患者的85只眼睛，使用Chiron微型角膜刀和Nidek EC - 5000准分子激光进行LASIK手术。术前平均近视度数为-2.09 D，平均散光度数为0.86 D。手术前排除了所有其他眼部病变。平均随访48天（范围1天至13个月）。
44只眼睛（52%）在1周时未矫正视力达到6/9或更好；68只眼睛（80%）在1个月时达到；70只眼睛（93%）在6个月时达到。疼痛评分最低，大多数患者术后无疼痛。一只眼睛发生了严重的术后角膜脓肿并发症，经治疗后痊愈，但留下了角膜瘢痕，视力为6/60。
LASIK是治疗低度近视的一种安全有效的手术方法；它还能使患者早期视力恢复，并显著减轻屈光手术患者的疼痛和不适。
