Abstract

The position of the apex of the cornea was found for 1000 "normal" eyes (500 right; 500 left) from photoelectronic keratoscopic analysis. The corneal apex was located on the vertical meridian in 21.3% of the eyes, temporally in 62.4%, and nasally in 16.3%. Although a temporally biased location for the corneal apex was demonstrated, 62.2% of the eyes had the apex within 0.5 mm of the visual axis. The implications of these findings in contact lens fitting are discussed.

摘要

通过光电角膜镜分析，对1000只“正常”眼睛（右眼500只，左眼500只）的角膜顶点位置进行了测定。角膜顶点位于垂直子午线的眼睛占21.3%，位于颞侧的占62.4%，位于鼻侧的占16.3%。尽管角膜顶点位置偏向颞侧，但62.2%的眼睛其顶点位于视轴0.5毫米范围内。文中讨论了这些发现对隐形眼镜验配的意义。
