Abstract

A study was designed to evaluate the usefulness of the Terry quantitative surgical keratometer as a tool to minimize surgically induced astigmatism. Two hundred and twenty-five phacoemulsifications with Shearing-style implants were performed, using identical technique. Seventy-five control cases were closed without the keratometer and 150 were closed with the keratometer. In the control group, 29.3% cases had corneal astigmatism of 3D or more, compared to 4.6% cases in the keratometer group (P < .01). The total change in astigmatism was 2.64D in the control group and 0.91D in the keratometer group (P < .02). We believe that these data demonstrate the usefulness of the Terry keratometer.
