AI Technical Summary

Technical Problem

Existing anterior segment thickness measurement technologies cannot guarantee image clarity due to variations in orbital depth, thus failing to meet the precise measurement needs of different populations.

Method used

Design an oblique image zoom lens, including a front fixed group, a moving group and a rear fixed group. The lens combination provides suitable optical zoom conditions for different depths of the eye socket. Combined with an illumination device, an optical path deflector and an imaging receiver, the lens is distributed in accordance with Scham's law to achieve clear imaging and accurate measurement of eye sockets at different depths.

Benefits of technology

It broadens the scope of application of measurement, improves the convenience of operation and the accuracy of measurement, ensures that the anterior segment parameters of the eye socket at different depths can be clearly imaged and accurately measured, and reduces measurement errors.
