Macular foveal myopia therapeutic instrument and using method thereof

Abstract

The invention relates to a macular foveal myopia therapeutic instrument and a using method thereof. The bottoms of the three lifting shafts are respectively fixedly mounted with a first longitudinal electric push rod, a second longitudinal electric push rod and a third longitudinal electric push rod, a fixed seat fixedly mounted on a bottom plate is disposed on one side of a mobile support platform, a junction box is fixedly mounted on the bottom of the fixed seat, one side of the junction box is connected to an external power line, and the other side of the junction box is respectively connected to a first switch, a second switch, a third switch, and a fourth switch, the first switch is connected to a horizontal electric push rod through a lead, and the second switch is connected to the first longitudinal electric push rod through the lead, the third switch is connected to the second longitudinal electric push rod through the lead, and the fourth switch is connected to the third longitudinal electric push rod through the lead; the image is presented on the peripheral retina, the long-term peripheral retinal vision development can treat myopia, the human resources can be saved, thecontrol efficiency can be improved, and the macular foveal myopia therapeutic instrument has good social and economic benefits.

Description

technical field [0001] The invention relates to the medical field, in particular to a central macular myopia treatment instrument and a method for using the same. Background technique [0002] The macula is located 0.35cm temporal to the optic disc of the fundus and slightly below it. It is in the optical center of the human eye and is the projection point of the visual axis. The macular area is rich in lutein and is darker than the surrounding retina. The depression in the center of the macula, called the fovea, is where vision is most acute. [0003] The ophthalmic medical community generally believes that too much close work and too little outdoor time are the main factors of myopia and eye fatigue. When a person focuses on one point with both eyes or one eye, the rod cells of the peripheral retina are in an inhibited state, and the retina outside the macula has great visual potential. When one or both eyes are fixed at one point, the equipment and methods are used to t...

AI Technical Summary

Problems solved by technology

[0004] Hyperopic defocus can promote the development of myopia. At present, there are many traditional devices and methods for treating myopia, but there are certain defects: if the curvature of the focal area is flatter than that of the retina, the focal area will be flatter when treating foveal myopia. Part of the retina moves behind the peripheral retina, resulting in reduced image resolution around the retina

An adverse side effect of axial elongation is when the focal point of the axial light moves away from the fovea, leading to recurrence of previously treated foveal myopia
