<P>PROBLEM TO BE SOLVED: To provide a space-saving and low-cost contact preventing mechanism for an intraocular pressure measuring device. <P>SOLUTION: The intraocular pressure measuring device includes: a spraying portion for spraying a gas to the cornea of an eye to be examined; and a pressure detecting portion for detecting the pressure of the gas sprayed by the spraying means. The device measures an intraocular pressure on the basis of an amount of deformation of the cornea caused by the sprayed gas by the spraying portion and a pressure detected by the detecting means. The intraocular pressure measuring device further has an elastic member having elasticity and filled with the gas in the inside, and determines whether an outside article contacts the elastic member or not on the basis of a change in pressure inside the elastic member detected by the pressure detecting means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
