November 30, 2007 updated by: Hospital Oftalmologico de Sorocaba

Visual Outcomes in a Comparison of Manual Penetrating Keratoplasty and the IntraLase® Enabled Keratoplasty

To compare the early visual results and postoperative recovery between two groups of keratoconic patients - one group having undergone a traditional, mechanical vacuum trephine procedure while the second group underwent femtosecond-enabled penetrating keratoplasty.
