Purpose:

To Asses the long-term Visual and refractive stability and ocular biometric changes in low to moderate myopic subjects treated by customized LASEK.

Methods:

In retrospective interventional case series study; 70 eyes of 35 patients that were treated by customized LASEK for correction of myopia <6.0 diopter were included. Uncorrected and distant corrected visual acuity (UCVA & DCVA), refractive outcomes and ocular biometric changes by LENSTAR LS900 (keratometry, anterior chamber depth (ACD), lens thickness and axial length) were evaluated preoperatively and eight years after operation.

Results:

The mean pre operative spherical equalent was -3.99 ± 1.37 diopter (D) that improved to .01 ± .27 and -0.11 ± .32 D 6 months and 8 years post operation respectively. The mean cylinder was -0.75± .66 that improved to -.19 ± .28 and -0.22 ± .32 D respectively. At 6 months and 8 years Log Mar UCVA and CDVA was 0.001, 0.000, 0.024, and 0.002. Keratometry and pachymetry decreased significantly after surgery but was stable during study. ACD decreased and lens thickness increased significantly over 8 years follow-up. Axial length wasn’t changed significantly.

Conclusion:

The long-term visual and refractive outcomes of customized LASEK in correction of low to moderate myopia are stable and predictable, although ocular biometric changes occurred.
