Abstract

PURPOSE

To report the refractive results after LASIK for mixed astigmatism at one center with one surgeon comparing two laser platforms.

METHODS

A total of 137 eyes of 69 patients were treated with LASIK for mixed astigmatism up to 3.33 diopters (D) using either the ALLEGRETTO WAVE 200- or 400-Hz laser (Alcon Laboratories Inc) between April 2006 and December 2009. The degree of astigmatism was higher in the 400-Hz group. Corneal flaps were created with the IntraLase femtosecond laser (Abbott Medical Optics) in all cases.

RESULTS

The refractive outcomes with both laser systems were statistically similar. At 6 months, 78% of eyes had 20/20 or better uncorrected distance visual acuity (UDVA) with all but one eye achieving 20/30 or better UDVA. At 6 months, 10% of eyes treated with the 200-Hz system lost one line of corrected distance visual acuity (CDVA) whereas no eyes treated with the 400-Hz system lost any lines of CDVA. Residual astigmatism was <0.50 D for all eyes treated with both platforms.

CONCLUSIONS

Both laser platforms provided predictable and effective treatment of mixed astigmatism in the patient populations treated, with over 90% of eyes achieving UDVA of 20/25 or better 6 months after surgery.

摘要

目的

报告一位医生在一个中心使用两种激光平台治疗混合散光的 LASIK 术后的屈光结果。

方法

2006 年 4 月至 2009 年 12 月，共有 69 例 137 只眼接受 LASIK 治疗混合散光，最高达 3.33 屈光度（D）。400-Hz 组的散光度数较高。所有情况下均使用 IntraLase 飞秒激光（Abbott Medical Optics）制作角膜瓣。

结果

两种激光系统的屈光结果具有统计学意义。术后 6 个月，78%的眼未经矫正的远视力（UDVA）达到 20/20 或更好，除 1 只眼外，所有眼均达到 20/30 或更好的 UDVA。术后 6 个月，200-Hz 系统治疗的 10%眼丧失 1 行矫正视力，而 400-Hz 系统治疗的无一眼丧失任何行矫正视力。所有眼的残余散光均<0.50 D。
