Myopia is very difficult to treat because it is an adaptation to the environment. In addition, the mechanism of myopia generation and progression is extremely complex and cannot be explained by a single mechanism.
Many factors are intricately intertwined, and the diversity of individual eyeballs is thought that it makes it difficult to elucidate it.
1．Inhibition of the progression of myopia
In the progression of myopia, the long-term strain of myopia is large (collapse of accommodation ability), and the long axis of the ocular axis is generated, and myopia progresses. Therefore, it is good if the load is taken, but in real life, we can not take such an approach for reasons such as studying. Inhibition of the progression of myopia without being invasive to the body and without using drugs with side effects, the following are effective.
- To releases overstrain of the ciliary body
- To improve blood flow of eyes
- Perceptual Learning
- When correction, done under a doctor
- Moderate exposure to ultraviolet rays (purple visible light) (effective only for children)
2．Effectiveness to Myopia
mechanism of 1
When looking near, the ciliary muscles contract and thicken the lens, and if this lasts for a long time, the ciliary muscles become stiff and cannot be thinned when looking far.
This is overstrain (accommodation tension), and at this stage, it can be cured by resting the eyes, eye drops, and stretching. There is an electric stimulation (current treatment) as a safe and immediate method of obtaining results.
First, naked eye vision highly increases as overstrain release (accommodation tension release).
However, the load of near vision lowers the visual acuity.
Therefore, in the case of application to adults, it is effective to treat as appropriate.
(This is also effective for visual acuity decrease after LASIK.)
In addition, in the case of children whose ocular axis has already begun to grow, their visual acuity gradually decreases. It can be said that the most inhibitory effect is to apply it to children regularly before the long axis of the eye begins.
In both cases, it is possible to inhibit the speed by electrical stimulation to some extent, but not completely.
In general, electrical stimulation strains the ciliary body, but if the amplitude (one of the current parameters) in Refresh Technology EW is weakened and the treatment time is set in a short time (5 to 10 minutes), the effect is effective because it acts on the release of overstrain.
We performed a treatment that applied refresh technology EW to about 200 myopic people, we think that the effect of releasing overstrain is high, because high naked eye vision improvement at the first treatment and deceleration in subsequent treatments have been observed.
