PROBLEM TO BE SOLVED: To provide a non-contact type tomometer capable of obtaining measurement values with high reliability, even if there are differences in a corneal thickness or a corneal hardness, by reducing the affection by the differences. SOLUTION: The tomometer is provided with a fluid blowing means for blowing a compressed fluid toward the cornea of an examined eye, a cornea deformation detection means for detecting the deformation of the cornea caused by the compressed fluid from the blowing means, a pressure detection means for detecting a pressure value of the compressed fluid blown against the cornea, an operating means for determining an intraocular pressure value based on the detection results by the cornea deformation detection means and the pressure detection means, a time determination means for determining a time from the start of cornea deformation to a prescribed deformed state, and a correction means for correcting the intraocular pressure value determined by the operating means based on the determined time by the time determination means.
