摘要
目的比较不同刀片制作老年患者准分子激光原位角膜磨镶术(LASIK)角膜瓣的差异。方法选择2008年1月—2012年1月82例行LASIK患者,随机分为二组。对照组40例80眼采用MoriaM2 110刀头,观察组42例84眼采用MoriaM2 90刀头。观察二组制作角膜瓣厚度的差异,并评价其保留角膜基质床厚度及并发症差异。结果观察组术后角膜瓣厚度显著低于对照组,差异有统计学意义(P<0.05);观察组保留角膜基质床厚度高于对照组,差异有统计学意义(P<0.05);观察组手术并发症发生率为6.0%低于对照组20.0%,差异有统计学意义(P<0.05)。结论不同刀片制作老年患者LASIK角膜瓣存在很大差异。MoriaM2 90刀头较MoriaM2 110刀头制作角膜瓣厚度更薄,同时其保留角膜基质床也较厚,患者手术并发症发生率也较低,能够获得更好的矫正效果,安全性高,值得临床推广。
Objective To compare the different blade production in elderly patients with excimer laser in situ keratomileusis （LASIK） difference of corneal flap. Methods A sample of 82 cases of LASIK in Wuhan Aier Eye Hospital between January 2012 and November 2013 were collected and then were randomly divided into two groups. A total of 40 cases and 80 eyes in the control group were performed with MoriaM2 110 head, 42 cases and 84 eyes in the test group were performed with MoriaM2 90 cutter head. To observe the differences of the corneal flap thickness in the two groups, and then to evaluate the diffrerence of its retention difference stromal bed thickness and complications. Results The postoperative corneal flap thickness in the test group was significantly lower than the control group, there was statistically significant （P〈0.05）. The thickness of corneal stroma bed retention in the test group was higher than the control group, there was statistically significant （P〈0.05）. The incidence of the operation complication in the test group was 6%, while it was 20% in the control group, and there had statistical significance （P〈0.05）. Conclusion There has difference on the blade production in elderly patients with LASIK corneal flap. The corneal flap thickness which was performed MoriaM2 90 knife head is thinner than that with MoriaM2 110 knife head and the incidence of operation complications with MoriaM2 90 knife head is lower than that with MoriaM2 110 knife head. The moriaM2 90 knife head can obtain better correction effect, high safety and is worth of the clinical promotion.
