  • Method and device for measuring intraocular tension
    Patent number: 7419470
    Abstract: An intraocular tension measuring method comprising vibrating an eyeball to be examined by a sound wave, measuring vibration of the eyeball to be examined by a noninvasive means to determine a Q value of resonance of the eyeball to be examined, and calculating intraocular tension from the Q value, and an intraocular tension measuring device comprising a vibrating means for vibrating an eyeball to be examined by a sound wave, a measuring means for noninvasively measuring vibration of the eyeball to be examined, a Q value calculating means for calculating a Q value of resonance of the eyeball to be examined from the vibration measured by the measuring means, and an intraocular tension calculating means for calculating intraocular tension from the Q value.
