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.
