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.
一项研究旨在评估特里定量手术角膜曲率计作为一种将手术引起的散光降至最低的工具的实用性。采用相同技术进行了225例使用剪切式植入物的超声乳化白内障吸除术。75例对照病例未使用角膜曲率计进行缝合,150例使用角膜曲率计进行缝合。在对照组中,29.3%的病例角膜散光为3D或更高,而角膜曲率计组为4.6%(P <.01)。对照组散光的总变化为2.64D,角膜曲率计组为0.91D(P <.02)。我们认为这些数据证明了特里角膜曲率计的实用性。
