Title: Kazunari Shimizu and Ultrasonic Eye-Pressure Measurement.
Introduction
Kazunari Shimizu is an inventor associated with Gamagori, Japan, and Nidek Corporation. His patent work includes technology for measuring intraocular pressure using focused ultrasound.
Latest Patents
Shimizu is credited with 1 patent: “Ultrasonic Tonometer and Non-Transitory Computer Readable Storage Medium.” The invention describes an ultrasonic tonometer that measures pressure in a subject’s eye. It uses a focused-ultrasound irradiation unit and a Z-alignment detection unit to identify the instrument’s position relative to the eye along the working-distance direction. The patent specifies an appropriate alignment position farther from the irradiation unit than its geometric focal position.
Career Highlights
Shimizu’s listed patent reflects work on applying ultrasonic technology to ophthalmic measurement. The design’s alignment feature is intended to help identify a suitable position for measuring intraocular pressure.
Collaborations
Shimizu’s listed coworkers include Tsutomu Uemura and Koji Hamaguchi. The available information identifies these colleagues but does not specify their roles in the patent.
Conclusion
Kazunari Shimizu’s patent describes an ultrasonic tonometer with a defined alignment approach for measuring intraocular pressure, connecting his inventive work with Nidek Corporation’s ophthalmic technology.
