<p>An improved tonomer (1) is disclosed having pachymric means (44, 46, 48) for measuring a patient's corneal thickness to allow for correction of the intraocular pressure measurement where the corneal thickness measurement deviates from a calibration mean corneal thickness. In a preferred embodiment, a single light source (50) is pulsed just prior to intraocular pressure measurement to illuminate a central section, and a pair of lateral light dector arrays (34a, 34b) are arranged to obliquely image the corneal section and generate signals which may be processed by a CPU (48) to produce a corneal thickness measurement. If the corneal thickness measurement deviates from the calibration mean corneal thickness, the CPU calculates a thickness corrected intraocular pressure measurement. The intraocular pressure measurement, corneal thickness measurement, and/or corrected intraocular pressure measurement may then be reported by reporting means (64).</p> |
