Clinical comparison of the Bausch & Lomb keratometer to the Alcon Renaissance series handheld keratometer

Abstract

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 significant difference was found between the two instruments for both axis and power
