Abstract

Purpose: To compare the level of higher-order aberrations (HOA) before and after laser-assisted in situ keratomileuses (LASIK) in myopic patients.

Methods: Uncorrected (UCDA) and best spectacle-corrected (BSCVA) distance visual acuity, intraocular pressure, and slit-lamp examination of anterior and posterior segments were done to all patients. Corneal topography, pachymetry, keratometry, and HOA was assessed with Oculus Pentacam II.

Moria M2 microkeratome was used to create the corneal flap, while the laser ablation was done with Allegretto 400 Hz laser. All surgeries were binocular and were done by the same surgeon. Four evaluation groups were formed according to the preoperative refractive error. Follow up was one week, 1, 3, 6, and 12 months postoperatively.

Results: A total of 263 patients (526 eyes) were enrolled in this study. A significant increase is noticed after the LASIK procedure in all cases, including the expected changes in pachymetry and keratometry values.

Conclusion: An increase of 64% in a third-order coma and fourth-order spherical aberration is seen postoperatively compared to preoperative values. The level of increase indirectly correlated with the ablation depth.
