Real damage information Israeli eye drops can treat myopia

Like contact lenses, Nanodrops cannot cure myopia but is just an alternative to wearing glasses.

A few days ago, information about a type of 'myopia eye drops ' in Israel made many people happy and waiting. It is called Nanodrops, which contains nanoparticles that can bind or 'permeate' the cornea, thereby altering the refractive properties.

Israeli scientists have taken advantage of this effect to overcome refractive errors on the cornea (an agent that causes paralysis and farsightedness) of 10 pigs. Research is said to be successful, causing many people to start waiting for a future where they only need eye drops.

But if you consult carefully, you will realize that it is a big misunderstanding, like what was advertised as 'touchless myopia ' in Vietnam before.

Not only is medicine out

Nanodrops was developed by Israeli scientists, under the cooperation of Shaare Zedek Medical Center and the Institute of Nanotechnology and Advanced Materials, belonging to Bar-Ilan University. It is a solution containing nanoparticles that can penetrate or 'permeate' into the cornea.

Nanodrops can be used to overcome myopia. But it is not simply that just putting this solution in the eye is able to regain sight. The process of using Nanodrops is complex, and at the very least, you still need to project laser light into your eyes when treating, not easily.

As described, Nanodrops contain nanoparticles that can bind or permeate the corneal surface, thereby altering the refractive index of the eye. When the refractive index is changed, it will pull the image in the eye of the near or far-sighted person (converging outside) to the correct position of the retina. So that people with eye problems can see clearly again.

Basically, small Nanodrops enter the eye like 'printing' a super-thin contact lens into the cornea, thinning under 1/10 millimeter. According to research by Israeli scientists, nanoprops in their Nanodrops solution have a diameter of 0.58 nm and penetrate 0.06 mm into the cornea (about one tenth of the average thickness of the cornea people).

Like contact lenses, Nanodrops can't cure myopia but is just an alternative to wearing glasses.

The principle of this method is similar to using contact lenses.

In addition, it is not easy to print a super-thin contact lens into the cornea. You can't just add Nanodrops to your eyes. First, scientists need to measure and model corneal defects. Then they create a laser model according to those defects called 'laser corneal stamping'.

Although the research overview is not clear, Nanodrops will probably be able to self-assemble and distribute according to different lighting models. Therefore, it will form the shape of a contact lens that scientists want.

Notably, Israeli scientists refuse to mention how long Nanodrops will maintain its effectiveness. Because the nanoparticles in the cornea may be gradually cleared, treatment will also lose its effect.

Here, printing a thin contact lens to the cornea seems like a tattoo, when the ink can be eliminated by blood cells over time, causing the tattoo to color and fade away. When this process occurs, myopia patient will once again have 'laser corneal stamping ', laser projection and medication again.

Obviously, 'myopia eye drops' are not as ideal and simple as you think.

So what is the potential of Nanodrops?

The ability of nanoparticles in Nanodrops to alter the corneal refractive index, thereby modifying its defects. This is also a non-invasive method, compared to other types of laser surgery. Nanodrops only attach nanoparticles to the cornea, rather than removing part of the cornea as myopia.

'Eye drops containing synthetic nanoparticles have shown promising potential to become a revolutionary, non-invasive refractive error repair procedure,' Israeli researchers wrote in the conclusion. comment.

This means that Nanodrops can be applied to both nearsightedness, farsightedness, and conditions of failure associated with corneas and other refractions.

Israeli scientists say they will proceed to human trials this year. However, they did not mention the preparation steps for this. The toxicity of Nanodrops is also something we don't know.

Distributing nanoparticles to the cornea is a difficult, even potentially high risk. If Nanodrops is successfully studied, this procedure may only be performed in medical facilities. It is not simply that you go to a pharmacy, buy Nanodrops home, and put it into your eyes to treat myopia.
