The newly introduced Renaissance Handheld keratometer from Alcon was compared for accuracy and ease or use with the B&L keratometer. Keratometer readings were obtained from 200 eyes (l00 subjects), as well as 4 steel balls and a contactometer. A high correlation between the two instruments was found on patients with clinically significant cylinder (>1.0D), with respect to both power and axis determination. A significant difference was found between the two instruments for both axis and power.
