目的比较去瓣Epi-LASIK和Epi-LASIK治疗中高度近视的术后病程和1年的临床结果.方法使用Amadeus Ⅱ角膜上皮刀分离28位中高度近视病人的角膜上皮瓣.随机选择病人的一只眼接受去瓣Epi-LASIK；另一只眼接受Epi-LASIK.使用TECHNOLAS 217Z100准分子激光机切削角膜基质.术后4至7天询问疼痛评分和疼痛时间,测量裸眼视力.术后2周、l、3、6月和1年检查裸眼视力、等值球镜、最佳矫正视力和Haze评分.结果术前Epi-LASIK眼和去瓣Epi-LASIK眼的等值球镜为(-7.39±2.21)D和(-7.69±2.38)D,P=0.12.术后4或5d、14 d,去瓣Epi-LASIK眼裸眼视力优于Epi-LASIK眼(P =0.01,0.046),且疼痛评分低于Epi-LASIK眼(P =0.049),两组术后疼痛时间相仿.术后其他时间点两组等值球镜和裸眼视力差异无统计学意义.术后1年两组间最佳矫正视力的变化行数差异无统计学意义.术后2周和3个月去瓣Epi-LASIK眼haze评分小于留瓣Epi-LASIK眼(P =0.00,O.0l).结论对于治疗中高度近视,去瓣Epi-LASIK比Epi-LASIK术后疼痛和Haze轻,而且术后视力恢复快.

Objective To compare the postoperative course and the clinical results of off-flap Epi-LASIK and Epi-LASIK for the treatment of moderate to high myopia for 1 year. Methods Corneal epithelial flaps of 28 patients with moderate to high myopia were separated with an Amadeus II epikeratome.A patient's eye was randomly treated with flap-off Epi-LASIK.The other eye was underwent Epi-LASIK.All patients' corneal stroma was ablated by TECHNOLAS 217Z100 excimer laser.Pain scores,pain time and uncorrected visual acuity (UCVA) were evaluated at the 4 to 7 days after surgery.UCVA,spherical equivalent,best corrected visual acuity (BCVA) and haze scores were recorded at 2 weeks,1 month,3 months,6 months and 1 year after surgery. Results The mean preoperative spherical equivalent of Epi-LASIK and flap-off Epi-LASIK were-7.39±2.21D and -7.69±2.38D,P =0.12.Compared with the Epi-LASIK eyes,the better UCVA at 4 or 5 and 14 days after surgery (P =0.01,0.046) and the lower pain scores (P =0.049) were found in off-flap Epi-LASIK eyes.Painful time had no significant difference between 2 groups.There was no significant difference between the 2 groups at the other postoperative intervals in terms of spherical equivalent and UCVA.There was no significant between-group difference in the change in lines of BCVA at 1 year after surgery.The lower level of haze scores at 2 weeks and 3 months after surgery (P=0.00,0.01) were found in off-flap Epi-LASIK eyes. Conclusions Off-flap Epi-LASIK offers the less postoperative pain,the lower level of haze formation and a faster visual recovery speed than Epi-LASIK for the treatment of moderate to high myopia.
