Moria M2型90刀头在LASIK手术中治疗高度和薄角膜近视患者的临床观察

Clinical observation of Moria-M2-90-mikrokeratome in LASIK for the patients with higher diopter or thinner corneal thickness

目的:观察MoriaM2型90刀头在治疗高度和薄角膜近视患者LASIK手术中的有效性和安全性。方法:采用MoriaM2型90刀头在不能行普通LASIK的高度近视和薄角膜的患者中行LASIK手术。结果:术后6mo裸眼视力≥1.0者,A,B组分别达95%,76.1%;裸眼视力≥0.5者,分别达100%,91.4%;术后6mo屈光度±0.75D,残余散光±0.50D,A,B组分别为16.4%,37.5%;97.1%术眼术后与术前相比,未有低于2行以上者。结论:使用M2型90刀头对于矫治高度近视和薄角膜患者行LASIK手术是安全有效的,远期结果需进一步观察。

AIM：To observe the efficacy and safety of the Moria-M2-9-mikrokeratome applied in LASIK for the patients with higher diopter or thinner corneal thickness.METHODS： Patients with higher diopter or thinner corneal thickness which can＇t treat in LASIK were treated with LASIK with Moria-M2-90-mikrokeratome, and followed up for more than six months. RESULTS： At six months postoperatively , uncorrected visual acuity was 1.0 or better in 136 eyes of A（95% ）, 160 eyes of B（76.1%）;0.5 or better in 148 eyes of A（100%）, 192 eyes of B（91.4） had a refraction with in ± 1.0DS or± 0.5DC,A,B is 16.4%,37.5% ;loss of 2 or more line of lest corrected visual acuity was observed in 97. 1% of the eyes. CONCLUSION： For the patients with higher diopter or thinner corneal thickness, application of Moria-M2-90- mikrokeratome in LASIK is an effective and safe procedure ,further study is needed to see the term surgery results.
