摘要
目的探讨Moria-M2自动旋切式显微角膜板层刀在用激光辅助原位角膜磨镶术(LASIK)治疗近视中的安全性和操作特点。方法采用法国Moria-M2自动旋切式显微角膜板层刀为558例、1 104只眼行准分子LASIK患者制作角膜瓣。刀头选择110(130μm)或130(160μm)厚的固定板层刀头;根据中央角膜曲率选负压吸引环(中央角膜曲率K值小于42D选-1 环,42-43D选0环,43-45D选+1环,45-47D选+2环);负压吸引环上的停止器档位选择7．5或8。结果作瓣过程中无卡刀、中途停顿及停停走走现象,角膜瓣边缘整齐,无锯齿样改变,角膜基质床光滑。术中并发症有“纽扣”瓣,发生率为 0．27％;游离瓣,发生率为0．09％;角膜瓣下基质床出现“岛屿现象”,即在基质床有不规则隆起,发生率为0．36％;走空刀发生率为0．09％;角膜瓣周边渗血发生率为0．45％;小角膜瓣发生率为0．09％。术中不良角膜瓣的发生率为0．815％。结论法国Moria-M2自动旋切式显微角膜板层刀安装方便,按角膜曲率选择负压吸引环及止刀器档位,制作角膜瓣效果好,无严重并发症,该刀安全性,稳定性好,值得临床推广应用。
Objective To investigate the safety with operate the characteristics of making corneal flaps with Moria- M2 auto-carriago-barraguer microkeratome in LASIK. Methods One thousand and one hundred zero four corneal flaps （in 558 cases） were made using Moria-M2 Auto-Carriago-Barraguer microkeratome in LASIK.The 130-um or the 160-um head option was chosen according to the central cornea curvatures,the stopring was adjusted to the 8 or 7.5. Results There was no breaking down during the surgical procedure.The flaps showed smooth edges with smooth keratectomy beds.Intraoperative complications：buttony flaps occurrence rate was 0.27%, free flaps occurrence rate was 0.09%, island phenomenon occurrence rate was 0.36%, failure to make the flaps occurrence rate was 0.09%, corneal flaps bloods in the perimeter occurrence rate was 0.45%, small corneal flaps occurrence rate was 0.09%, the bad corneal flaps occurrence rate was 0.815%. Conclusion Moria-M2 auto-carriago-barraguer microkeratome is easy to be installed.The suction ring and the stoping are chosen according to corneal curvature. No serious complications when making corneal flaps with Moria-M2 auto-carriago-barraguer microkeratome.The knife has better safety and stability,deserve the clinical expansion application.
