Abstract: A fundus examination device aiding in gaze fixation and image focusing includes a light projecting device for projecting an examination light to illuminate an examinee's fundus; an illuminating system for transmitting the examination light to the examinee's eye and receiving a fundus image; an imaging system for showing the fundus image; and a focusing and gaze-fixation device located in the illuminating system and including a focus mask formed in a focusing zone, on which the examinee's eye focuses. The focus mask includes a split image screen surrounded by a light-penetrable structure, and gaze fixation devices for forming gaze-fixation images at examinee's eye focusing positions within the focusing zone, such that the split image screen and the gaze-fixation images are located at different focal positions corresponding to the examinee's eye curvature. Therefore, when a split image focusing is completed, the gaze-fixation images are also located at clearly recognizable focal positions.

Abstract: An optical device for corneal measuring includes a light source module, a first optical module, a second optical module including a reference mirror, a light splitter and an image analysis unit. The light of the light source module is transmitted to the first and second optical modules through the light splitter. The light is transmitted to a cornea through the light splitter and the first optical module and reflected by the cornea to form a first light, the light is transmitted to the reference mirror through the light splitter and reflected by the reference mirror to form a second light. The first and second lights are transmitted to the light splitter and the image analysis unit. The reference mirror moves along a first direction, and when the first light and the second light interfere with each other, a relative optical path length is obtained.
