Adjustable artificial crystal based on micro-opto- electro-mechanical system

Abstract

The invention relates to an adjustable artificial crystal based on micro-photo dynamoelectric system, belonging to field of biological medicine engineering. The invention comprises a zoom-lens system that be embedded into eye and a control system out of eye. Said zoom-lens system comprises: positive lens, negative lens, signal and energy receiving coil, artificial crystal, singal treating and controlling unit, micro-motor and guide rail. Said control system comprises: signal and energy receiving coil, infrared distance-measuring unit, energy supply unit and glass frame. Said control system comprises zoom-lens system with combined functions of energy supply, distance measuring, coupling signal with energy into eyes; said zoom-lens system possesses functions of receiving, treating and controlling signal and energy. The negative lens are moved in axial direction drove by micro-motor, to change the diopter and ensure target object be imaged on retina accurately at real time.

Description

technical field [0001] The invention relates to an artificial lens in the technical field of biomedical engineering, in particular to an adjustable artificial lens based on a micro-opto-electromechanical system. Background technique [0002] The lens of the human eye has the function of adjusting the diopter by changing the shape. At present, in clinical ophthalmology, after lens extraction and intraocular lens implantation, the affected eye loses this function. Even if the eye is worn after the operation, it is generally only possible to achieve clear vision at a single distance. Although people use multifocal designed intraocular lenses or utilize the function of the ciliary muscle to achieve a certain degree of eye adjustment, the clinical effect is not good. Multifocal intraocular lens is made by using aspheric optics to make the intraocular lens have multiple optical powers at the same time, so as to realize the vision requirements of different distances for the implan...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an adjustable intraocular lens based on the micro-opto-electromechanical system, so that it can use the micro-opto-electromechanical technology to produce an adjustable artificial lens that can change the focal length and can be implanted in the eye. The lens system meets the needs of vision at different distances when implanting artificial lenses after cataract extraction and restoring the visual function of the blind
