Title: Noncontact ophthalmotonometer
Inventor: ITOH HIROSHI
IPC: A61B3/16
Filed: 2002-11-15
Abstract: PURPOSE: To enable even an unskilled examiner to easily operate a non- contacting ophthalmotonometer. CONSTITUTION: When measurement is started, a step S1 performs image processing to an imaged video signal to extract a pupil part, calculates the position of a centroid and moves a measurement mechanism so that the position of the centroid may become the position of the center axis of a nozzle. A step S2 detects the positions of a pair of alignment index images from the video signal, and calculates a distance from the tip of the nozzle to a cornea from an internal between the positions of the centroid. When the tip of the nozzle approaches the cornea C, the measurement mechanism is moved in the direction of separating from the cornea. A step S3 moves the measurement mechanism in the direction of approaching the cornea in the direction of the center axis of the nozzle to detect a second index image by a second alignment index light source. A step S4 performs precise positioning by using the second index image. When alignment is completed, a step S5 measures intraocular pressure. When it is finished, a step S6 moves the measurement mechanism to a position most separated from the eye to be examined in the direction of the center axis of the nozzle.
