Abstract
A non-contact type tonometer is disclosed, wherein a fluid blowing device blows a compressed air against a cornea of an examinee's eye, a deformation detection device detects a corneal deformed state caused by the fluid, a pressure detection device detects the fluid pressure to be blown by the fluid blowing device, a memory samples data on time-varying pressure detected by the pressure detection device at predetermined time intervals and stores them, and a calculation device takes a predetermined amount of pressure data from those stored in the memory, the pressure data being within a predetermined duration determined relative to the reference time at which a predetermined deformation of the cornea is detected by the deformation detection device. Then, the calculation device calculates an intraocular pressure of the examinee's eye based on the taken pressure data.
