Correlation Analysis of Refractive and Visual Quality after Wavefront-Optimized Laser In Situ Keratomileusis for 50% and 100% Angle Kappa Compensation.

Purpose: To analyze the distribution of the offset between the pupil center and the coaxially sighted corneal light reflex (), the effects of 50% and 100% angle kappa adjustments on refractive and visual quality in patients with moderate myopia were investigated.

Methods: A randomly selected 254 patients (254 eyes) with moderate myopia who underwent femtosecond laser-combined LASIK were examined. During the operation, the of the patients was recorded by the and y-axis eyeball-tracking adjustment program of the WaveLight Eagle Vision EX500 excimer laser system.
