Comparison of a Laser Keratome to a Mechanical Microkeratome

August 17, 2006 updated by: Medical University of South Carolina

Comparison of INTRALASE® to AMADEUS™ Microkeratome

The purpose of this study was to evaluate the performance of the INTRALASE®, a laser keratome which creates a corneal flap, and compare it to a mechanical microkeratome (Amadeus™). Our hypothesis is that there is no difference between the 2 devices.
