METHOD AND APPARATUS FOR FIXATION MEASUREMENT AND REFRACTION ERROR MEASUREMENT USING WAVE-FRONT ERROR

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for fixation measurement that measures information indicating fixation of eyes from a reflected image including light reflected from the eyes.;SOLUTION: A method and apparatus for fixation measurement are provided, including the steps of: projecting, by an image projector 16, a stimulus onto one or more eyes of a patient via a beam splitter 14; and capturing, by one or more image sensing devices 43 disposed conjugate to the one or more eyes 12A, B, a reflected image including light reflected from the one or more eyes in response to the stimulus. The reflected image includes information indicating the fixation of the one or more eyes.;SELECTED DRAWING: Figure 1B;COPYRIGHT: (C)2019,JPO&INPIT
