Abstract

EDITORIAL VERYONE WHO has excised a cornea has had the accuracy of tonometry in individual cases?” If the the opportunity to observe that the normal answer is yes, then the next question is, “What kind of cornea tends to maintain its watch-glass correction should be applied and for what tonometers shape if external forces due to pressure, grav- would such a correction be relevant?” For this question E ity, and surface tension are neutralized. This the answer is less clear. inherent stiffness of the cornea has been a subject of study Ehlers et al have published a Table that could be used for those interested in the accuracy of applanation tonom- for such a purpose, and this table has been used in the pres- etry, beginning with the inventive work of Goldmann and ent article by Copt et al to reclassify their cases. In this table, Schmidt in the middle of this century. It is reasonable to the average error of tonometry induced by a greater or lesser assume that the stiffness of the cornea would vary some- corneal thickness is 0.7 mm Hg per a 10-μm deviation from what from one person to another and that this property
