Abstract Details

Purpose:

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

Setting:

Setting: Eye research center, Rassoul Akram Hospital, Iran University of Medical Sciences and Iranian Eye Clinic, Tehran, IRAN.

Methods:

71 eyes of 36 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 the operation.

Results:

The mean preoperative spherical equivalent 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 the study. ACD decreased and lens thickness increased significantly over 8 years follow-up. Axial length wasn’t changed significantly.

Conclusions:

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