Intraocular pressure measurements with the Goldmann and Schiotz tonometers are unreliable when the cornea is irregular due to disease or surgery. The Tono-Pen (Oculab, Glendale, Calif) is an electronic applanation tonometer based on the same principle as the MacKay-Marg tonometer. We measured intraocular pressure in 37 eyes with irregular corneas, in 50 eyes that had recently undergone penetrating keratoplasty, in 16 eyes that had undergone epikeratophakia, and in 12 eyes with normal corneas with both the MacKay-Marg and Tono-Pen tonometers. The same two instruments were used, and the sequence of measurement was randomized. Analysis of variance demonstrated no significant difference between measurements obtained with the two tonometers in any of the groups. The data suggest that the Tono-Pen is as accurate as the MacKay-Marg tonometer in those situations where the Goldmann tonometer is inaccurate.
当角膜因疾病或手术而不规则时，使用戈德曼眼压计和施茨眼压计测量眼压是不可靠的。托诺笔眼压计（Oculab公司，加利福尼亚州格伦代尔）是一种电子压平眼压计，其原理与麦凯-马格眼压计相同。我们使用麦凯-马格眼压计和托诺笔眼压计，对37只角膜不规则的眼睛、50只近期接受穿透性角膜移植术的眼睛、16只接受表层角膜镜片术的眼睛以及12只角膜正常的眼睛进行了眼压测量。使用了相同的两种仪器，测量顺序是随机的。方差分析表明，在任何一组中，两种眼压计所测得的结果之间均无显著差异。数据表明，在戈德曼眼压计不准确的情况下，托诺笔眼压计与麦凯-马格眼压计一样准确。
