Moria2自动旋转式角膜板层刀在LASIK术中应用的探讨

目的探讨Moria2自动旋转式角膜板层刀在LASIK术中应用效果。方法用Moria2自动旋转式角膜板层刀对187例（367眼）屈光不正患者进行LASIK治疗。结果术后367眼中有360眼（98．1％）视力达到术前最佳矫正视力。术中角膜瓣的并发症发生率为1．4％，其中1眼为游离瓣，1眼薄瓣伴破瓣，1眼为薄瓣伴厚度不匀，术后角膜瓣均无上皮内生，2眼角膜层间沙漠样反应。术中先上吸环后上刀头做角膜瓣吸引时间（19．4±3．1）s，先上刀头后上吸环做角膜瓣吸引时间（16．6±2．7）s，其差异有统计学意义（t=3．469，P=0．001）。结论Moria2自动旋转式角膜板层刀术中操作简单，安全性高，角膜瓣、蒂的位置和大小选择性强，易于掌握。

Application of Moria-2 auto-carriago-barraguer microkeratome in LASIK

Objective To study the application of Moria-2 auto-carriago-barraguer microkeratome in LASIK. Methods LASIK was performed for 367 eyes （187 patients） using Moria-2 auto-carriago-barraguer microkeratome. Results The best corrected visual acuity was achieved in 360（98.1%） out of the 367 eyes after LASIK. The intra-operative complication rate of corneal flaps （free flap, thin broken flap and different thick flaps of 3 eyes, respectively） was 1.4%. No ingrown of epithelium was observed in corneal flaps after LASIK. However, desert -like reaction occurred in the corneal layer of 2 eyes. There was a statistical difference in absorbing time （seconds） between the first absorbing ring and the knife（19.4 ±3.1 ）s and vice versa（16.6± 2.7）s （t=3.469, P=0.001）. Conclusion Moria-2 auto-carfiago-barraguer microkeratome is easy to operate and high in safety, and therefore can be used in LASIK.
