Paracentral corneal topography was determined (with a topogometer) and corneal sensitivity was measured in 90 keratoconic eyes. Sensitivity was evaluated in a control group and found to be greater in all five sectors than the sensitivity found in keratoconus patients. The zone of marked corneal steepening was located infero-temporally in 59% of our patients, although steepening was found in other zones as well. Overall, sensitivity was greatest in the temporal cornea and lowest in the inferior cornea, this hypoesthesia coinciding with the area of pronounced corneal protrusion. Corneal sensitivity, which was diminished in contact lens wearers, recovered within 7 days after discontinuing contact lens wear.
使用角膜地形仪测定了90只圆锥角膜眼的中央旁角膜地形图，并测量了角膜敏感性。在一个对照组中评估了敏感性，发现所有五个区域的敏感性均高于圆锥角膜患者的敏感性。在我们59%的患者中，明显角膜陡峭区域位于颞下，但其他区域也发现有陡峭情况。总体而言，敏感性在颞侧角膜最高，在下侧角膜最低，这种感觉减退与明显角膜突出区域一致。在佩戴隐形眼镜的患者中角膜敏感性降低，在停止佩戴隐形眼镜后7天内恢复。
