Preoperative and postoperative evaluation included uncorrected distance visual acuity (UCDVA), best corrected visual acuity (BCVA), spherical equivalent (SE), slitlamp biomicroscopy, applanation tonometry, fundus examination, B-scan biometry, specular microscope and corneal topography. Topography was performed in all patients using the EyeSys unit (Version 3.03; EyeSys Technologies, Houston, Texas). The corneal endothelial cell count was also recorded for all eyes (noncontact specular microscope, NonCon Robo, Konan). The visual acuity measurements were recorded with logMAR UCDVA and BCVA. Clinical data were collected preoperatively and 1 and 3 months postoperatively for each eye.
