Abstract

The binocular stereoscopic visual simulating system for correcting high order aberration consists of two sets of adaptive optical beacon, beam expanding system, reflectors, beam splitter, human eyes, light beam matching telescopes, wave front corrector, Hartmann wave front sensor, computers, high voltage amplifier, optical imaging system, visual discernibility display. By means of the said system, the patient can sense the binocular visual effect of operation or high order aberration correction during determining operation scheme or customizing the personal contact lenses. The present invention makes it possible for the patient and the doctor to optimize operation scheme or design scheme commonly, to optimize the parameters of the contact lenses in advance and to establish the relationship between objective measurement data and subjective visual sensing.

Description

Technical field [0001] The invention relates to a binocular stereo vision high-order aberration correction visual simulation system, which is a simulation system used for the simulation of high-order aberrations of human eyes before surgical correction, or before the configuration of personalized high-order aberration contact lenses of human eyes. Optical instrument for stereoscopic vision effect after human eye operation or contact lens configuration. Background technique [0002] Since the former Soviet scientists invented Radial Keratotomy (RK) to correct vision in the 1970s, with the advancement of laser technology and photoelectric technology, excimer laser corneal ablation (Photorefractive Keratotomy-RK) appeared in the 1990s. , Excimer laser in situ keratomileusis (Laser in SituKeratomileusis-LASIK) developed in the late 1990s, these technologies have developed into outpatient surgery in recent years. These operations use a scalpel, laser to cut corneal tissue, and c...
