目的比较超薄角膜瓣LASIK和LASEK在治疗角膜相对较薄的高度近视时的患者自觉症状、满意度、疗效、预测性、安全性等.方法随机选择角膜相对较薄的高度近视患者分为两组.使用超薄角膜瓣LASIK治疗的患者设为A组:25人(50只眼);球镜度-6.00～-10.0D,平均-7.18D;柱镜度0～-2.00D,平均-0.84D.使用LASEK治疗的患者设为B组:25人(50只眼);球镜度-6.00～-10.00D,平均-7.15D;柱镜度0～-2.00D,平均-0.96D.两组各指标分别于治疗后1周、1、3、6、12个月检查并记录裸眼视力、矫正视力、等效球镜度、并发症等情况并进行比较.结果 A组平均角膜瓣厚度为(96.76±5.54)μm;术后反应较轻,疼痛及其他不适症状较轻,患者满意度较高;激素眼液使用时间短;裸眼视力恢复较快.B组术后反应较重,疼痛及其他不适症状较重;激素眼液使用时间长;裸眼视力恢复较慢;且术后6个月后发生屈光回退的眼数较多.两组均未见影响视力的严重并发症,LASEK组并发症主要为屈光回退和haze.结论 MoriaM2型90刀头适合临床LASIK超薄角膜瓣制作,超薄瓣LASIK的安全性和有效性方面与LASEK相同,而治疗后的稳定性及患者满意度优于LASEK.更大样本和更长时间的临床研究有待于继续进行.

Objective To compare the subjective symptom,curative effect,efficacy and safety of the ultra-thin flap LASIK and LASEK for the treatment of high mypia with relative thin cornea.Methods 100 eyes of 50 cases with high mypia with relative thin cornea were divided into two groups.50 eyes of 25 cases received ultra-thin flap LASIK were included in group A.50 eyes of 25 cases received LASEK were included in group B.The mean preoperative spherical equivalent was -7.18D(range from -6.00～-10.0D)and -7.15D (range from -6.00～-10.0D)respectively.The subject symptom,degree of satisfaction,uncorrected visual acuity,best corrected visual acuity,spherical equivalent and complications were observed and compared during after surgery.Results The average flap thickness was(96.76± 5.54)μ m.Postoperative visual acuity of group A recovered faster with less steroid use than of group B.The degree of satisfaction of guoup A is bettet than group B.There were no threatening complications for vision in both group.The main complications were haze and regression in group B.Postoperative reaction was mild in group A patients,who showed a quick recovery in UCVA.Conclusion Moria-M2-90-mikrokeratome is fit for LASIK with ultra-thincorneal flaps.LASIK with ultra-thin corneal flaps for high myopia with relative thin cornea is safe,effective and comfortable.LASIK with ultra-thin corneal flaps may be better than LASEK.It needs further clinical study with larger scale and longer follow-up.
