A Comparison of the Humphrey Autokeratometer and System 2000 with the Bausch and Lomb Keratometers

Résumé

A series of clinical evaluation tests were performed to compare the performance of the Humphrey Model 410 Autokeratometer and Wesley Jessen System 2000 with a conventional Bausch & Lomb keratometer considered as a reference standard. Both of these semi-automated instru­ments seemed to give consistent, reliable, and accurate results relative to the conventional kerato­meter; despite its much higher cost, the autokera­tometer however appears to be the most practical instrument in a large practice because of the very high speed with which results are printed out.
