ABSTRACT:
An improved apparatus and method of intraocular pressure determination is disclosed in which applanation tonometry is done with an ultrasonic transducer. The method allows for increased accuracy of intraocular pressure determination based upon adjustment of applanation tonometry for subjacent corneal thickness. The device allows for the operator to view the corneal surface and the pattern of dye to determine the precise endpoint of applanation.
