Semiconductor laser apparatus for treating amblyopia

Abstract

A semiconductor laser instrument for treating amblyopia is composed of control unit, voltage regulator, current regulator, timer, and semiconductor laser device.

Description

technical field [0001] The invention relates to a semiconductor laser treatment device for amblyopia, which uses a cone-sensitive semiconductor laser (wavelength 630-650nm) to stimulate the cone cells in the macular area of ​​the fundus, so that the cone cells are benignly stimulated, and the function of the cone cells is activated to achieve effective The purpose of treating amblyopia. Background technique [0002] Amblyopia is caused by non-organic lesions, and those whose corrected visual acuity is less than 0.9 due to functional factors are called amblyopia. There are many treatment methods for amblyopia, including covering method, depression therapy, grating therapy, afterimage method and red light filter therapy, fine work training and synoptic machine training, etc. [0003] At present, the amblyopia treatment devices on the market use light-emitting diodes as red and green divergent light sources or use ordinary colorless or colored light sources as visual stimulati...

AI Technical Summary

Problems solved by technology

[0003] At present, the amblyopia treatment devices on the market use light-emitting diodes as red and green divergent light sources or use ordinary colorless or colored light sources as visual stimulation sources. However, these light sources are divergent light sources with a large wavelength range, which can effectively stimulate cone cells. The proportion of the light wave is small, which can not make the cone cells produce effective excitatory stimulation, and the purpose of treatment cannot be achieved; there is also a kind of amblyopia treatment instrument with He-Ne laser as the light source on the market. This kind of pulsed laser, in order to effectively stimulate the average power of the cone cells, the instantaneous power of the laser must be large, which is easy to cause a certain degree of damage to the cornea
