Abstract
Radial keratotomies can be performed by incising centrifugally. A vibrating diamond front cutting blade with a reverse cutting edge incises centrifugally to form a squared-off incision at the optical zone. The incision can be retraced if an enhancement is necessary with the vibrating blade without tearing the collagen or resulting in blade setting variability or variability due to corneal compression.
