COMPARISON OF 3 KERATOMETRY INSTRUMENTS

We compared the reliability of measurements of three keratometers and keratometry readings from a corneal topography system to determine if they were as accurate as the ''gold standard'' Javal-Schiotz keratomet er. Same-day measurement of the steepest and flattest powers of the ce ntral 3 mm of the corneas of 200 eyes (100 patients) revealed no stati stically significant difference in reliability between the newer kerat ometers and the Javal-Schiotz. In addition, the newer machines are mor e convenient and efficient in some clinical settings.
