Abstract:
1. A noncontact tonometer comprising: fluid blowing means for blowing fluid onto a cornea to deform the cornea; measuring-light projecting means for projecting measuring light onto the cornea; corneal deformation detecting means for detecting the measuring light reflected by the cornea when the cornea is deformed by the fluid so as to have a predetermined curvature radius; calculating means for calculating intraocular pressure on the basis of the detection by the corneal deformation detecting means; control means for controlling measuring operations of the noncontact tonometer performed sequentially a predetermined number of times; and comparing means for comparing the intraocular pressure obtained by the calculating means for each of the predetermined times with a predetermined limit, wherein the control means gives a warning if the intraocular pressure obtained by the calculating means for at least one of the predetermined number of times exceeds the predetermined limit.
