PURPOSE
To evaluate a surgical technique used in eyes with narrow palpebral fissure undergoing femtosecond laser flap creation without suction during laser in situ keratomileusis (LASIK).
METHODS
All data of 2 patient groups were collected through chart review. Group 1 consisted of 6 eyes with narrow palpebral fissure in which the suction ring was manually fixated and femtosecond laser was applied accordingly. Thirty comparison cases were randomly drawn from among eyes that underwent a standard LASIK procedure matched for age and preoperative refraction (group 2). Only 1 eye of each patient was selected to compare the refractive and visual outcomes between groups.
RESULTS
In all group 1 eyes, the flaps were created successfully with manual fixation of the suction ring without suction. No eyes lost 2 or more lines of vision. No significant difference was found in the safety and refractive outcomes between groups.
CONCLUSION
Manual fixation of the suction ring in eyes with narrow palpebral fissure without suction was feasible for flap creation during LASIK.
目的
评估在准分子原位角膜磨镶术（LASIK）中，用于睑裂狭窄眼睛的一种在无负压吸引情况下制作飞秒激光角膜瓣的手术技术。
方法
通过查阅病历收集2组患者的所有数据。第1组由6只睑裂狭窄的眼睛组成，其中通过手动固定负压环并相应地应用飞秒激光。从年龄和术前屈光度匹配的接受标准LASIK手术的眼睛中随机抽取30例对照病例（第2组）。每组仅选择1只眼睛来比较两组之间的屈光和视觉结果。
结果
在第1组所有眼睛中，通过手动固定负压环在无负压吸引的情况下成功制作了角膜瓣。没有眼睛视力下降2行或更多。两组之间在安全性和屈光结果方面未发现显著差异。
结论
在无负压吸引的情况下，对睑裂狭窄眼睛手动固定负压环在LASIK手术中制作角膜瓣是可行的。
