Comparison of wavefront-guided aspheric laser in situ keratomileusis for myopia: coaxially sighted corneal-light-reflex versus line-of-sight centration.

Purpose: To compare refractive outcomes, higher-order aberrations (HOAs), and contrast sensitivity of myopic wavefront-guided aspheric laser in situ keratomileusis centered on the coaxially sighted corneal light reflex or on the line of sight.

Setting: Okamoto Eye Clinic, Ehime, Japan.

Design: Comparative case series.

Comparison of myopic LASIK centered on the coaxially sighted corneal light reflex or line of sight.

Purpose: To compare refractive outcomes of myopic LASIK with centration on the coaxially sighted corneal light reflex (CSCLR) to centration on the center of the pupil (line of sight [LOS]).

Methods: The NIDEK CXIII excimer laser was used to treat 268 eyes with centration on the CSCLR (CSCLR group) and 288 eyes with centration on the LOS (LOS group). For the CSCLR group, the laser ablation was delivered 80% closer to the visual axis.
