PURPOSE
To evaluate risk factors, management, and outcomes in patients who experienced suction loss during LASIK flap creation with a femtosecond laser (Intra-Lase FS 60, Abbott Medical Optics Inc).
METHODS
Pre- and postoperative visual outcomes and refractions for 71 eyes of 70 patients after suction loss during flap creation with the IntraLase FS60 femtosecond laser were analyzed and studied.
RESULTS
In patients requiring a second or third lamellar flap cut immediately after suction loss, 97.2% of eyes achieved uncorrected distance visual acuity of 0.00 logMAR (20/20) or better and 100% of eyes achieved corrected distance visual acuity of 0.00 logMAR (20/20) or better at most recent follow-up.
CONCLUSIONS
Our study suggests that excellent visual outcomes can be achieved if an immediate lamellar recut is performed after suction loss with a femtosecond laser.
目的
评估在使用飞秒激光（Intra-Lase FS 60，Abbott Medical Optics Inc.）进行 LASIK 瓣制作时发生吸引损失的患者的风险因素、处理方法和结局。
方法
对 70 例患者的 71 只眼在使用 IntraLase FS60 飞秒激光进行瓣制作时发生吸引损失后的术前和术后视力结果及屈光度进行分析和研究。
结果
在需要立即进行第二次或第三次板层瓣切割的患者中，97.2%的眼术后未矫正远视力达到 0.00 logMAR（20/20）或更好，100%的眼在最近的随访中达到矫正远视力 0.00 logMAR（20/20）或更好。
结论
我们的研究表明，如果在飞秒激光发生吸引损失后立即进行板层再切割，可以获得极佳的视力结果。
