Pupillary Diameter Change and Dynamics in Different Refractive Error Groups after Implantation of a Collamer Lens with a Central Hole Without Viscoelastic Agent

Abstract

Background: To investigate the pupillary diameter and dynamics in different refractive error groups after non viscoelastic agent assisted implantation of a collamer lens with a central hole, so as to evaluate the effect on the pupil of this type of surgery.
