"Glare is induced by rays of light that enter the pupil through the portion of the cornea outside the ablation area. A larger pupil allows more errant light rays to reach the retina and degrade the perceived image. For this reason, a larger ablation zone is required in patients with large pupils and high myopic corrections".
