To demonstrate the practical and functional evaluation of flaps created intraoperatively by femtosecond laser using anterior segment optical coherence tomography (AS-OCT).
The study prospectively examined 11 eyes of 6 patients who underwent uneventful LASIK surgery with the aid of the IntraLase femtosecond laser (IntraLase Corp., Irvine, CA). During the waiting period between femtosecond laser and excimer laser, all eyes were evaluated by AS-OCT to image each flap immediately before flap lifting and laser ablation. Flap thickness and residual stromal bed thickness were calculated automatically using the software's flap tool.
A uniform flap was created by femtosecond laser not only in the central cornea, but also in all quadrants.
The qualitative and quantitative evaluation of the corneal flap created by a femtosecond laser using AS-OCT before lifting the flap confirms that the femtosecond laser is a practical intraoperative approach that offers a safer surgery.
利用眼前节光学相干断层扫描(AS-OCT)对飞秒激光术中制作的角膜瓣进行实用性和功能性评估。
本研究前瞻性地检查了6例患者的11只眼睛,这些患者在IntraLase飞秒激光(IntraLase公司,加利福尼亚州欧文市)辅助下顺利接受了LASIK手术。在飞秒激光与准分子激光治疗的间隔期,使用AS-OCT对所有眼睛进行评估,以在掀起角膜瓣和激光消融前即刻对每个角膜瓣成像。使用软件的角膜瓣工具自动计算角膜瓣厚度和剩余基质床厚度。
飞秒激光不仅在角膜中央,而且在所有象限均制作出了均匀的角膜瓣。
在掀起角膜瓣前,使用AS-OCT对飞秒激光制作的角膜瓣进行定性和定量评估证实,飞秒激光是一种切实可行的术中方法,可使手术更安全。
