Effects of Corneal Anatomical Match Between Donor and Recipient During DALK Surgery on Final Visual and Refractive Outcomes in Patients With KCN

Shahid Beheshti University of Medical Sciences52 enrolled

Overview

Patients with KCN who undergo cornea transplantation divided to 2 groups: Group1: After mechanical trephination, horizontal meridian of donor's cornea sutured to horizontal meridian of recipient cornea Group 2: After mechanical trephination, horizontal meridian of donor's cornea sutured to vertical meridian of recipient cornea After suture removal, best corrected visual acuity, refractive error, corneal keratometry, irregularity of corneal surface and high order aberration of two groups will compare
