Abstract: A simplified and cost-effective three-axis positioning device and method for ophthalmic examination instrument is disclosed. The three-axis positioning device includes an illuminating optical path for projecting light to illuminate an examinee's fundus; an imaging optical path including an objective lens for receiving the examinee's fundus image and light reflected from the examinee's cornea and eye-lens; a software-based alignment module for determining intensity and position of the reflected light on the fundus image to generate auxiliary positioning information; and an image displaying unit for showing the fundus image, the reflected light, and the auxiliary positioning information. From the intensity and position of the reflected light, x-, y- and z-axis relative positions between the examinee's pupil and the objective lens are obtained. An examiner adjusts the relative positions in three axes until they fall within an allowable deviation range, and a clear fundus image can be obtained.
