Abstract

PURPOSE

To prospectively compare the achieved thickness and consistency of LASIK flaps created with a 60- and 150-kHz femtosecond laser.

METHODS

One hundred twenty eyes of 60 patients with myopia were treated with LASIK. One eye had flap created by the Intralase FS 60-kHz femtosecond laser (Abbott Medical Optics, Abbott Park, IL) and the fellow eye was treated with the IntraLase iFS 150-kHz femtosecond laser (Abbott Medical Optics). Eyes were randomized according to ocular dominance. Flap morphology and measurements were taken with anterior segment optical coherence tomography (AS-OCT) at the 1-month postoperative visit.

RESULTS

AS-OCT showed similar regular planar morphologies in both groups. The mean thickness of the flaps in the FS 60 group was significantly higher than that of the iFS 150 group (105.4 ± 3.9 μm vs 103.9 ± 4.8 μm, P = .009). The mean deviation from targeted flap thickness was not significantly different between the two groups.

CONCLUSIONS

The Intralase iFS 150-kHz femtosecond laser creates flaps of similar thickness and uniformity to the Intralase FS 60-kHz femtosecond laser.

摘要

目的

前瞻性比较使用60kHz和150kHz飞秒激光制作的LASIK瓣的厚度和一致性。

方法

60例近视患者的120只眼接受了LASIK治疗。一只眼使用Intralase FS 60kHz飞秒激光（雅培医疗光学，伊利诺伊州雅培公园）制作瓣，另一只眼使用IntraLase iFS 150kHz飞秒激光（雅培医疗光学）治疗。根据眼优势将眼随机分组。术后1个月随访时，使用眼前节光学相干断层扫描（AS-OCT）进行瓣形态和测量。
