Health: innovations against myopia

Half of the planet should be nearsighted by 2050. This is the result of a study by the Institute of Vision at the University of New South Wales, Australia, released this year. It is therefore not surprising that scientific research against this visual disorder goes further and further. Overview of the latest innovations against myopia.

What is myopia ?

A shortsighted person has difficulty seeing from a distance . On the other hand, her sight is clear when she looks at an object or a person close to her. What are the causes of this vision disorder? Myopia occurs when the eye is too long from the front to the back of the eye. It can also be the consequence of a cornea too curved. Result: the light is concentrated in front of the retina and not on it, which blurs the objects in the distance. It can occur at any age, although it is often the case before thirty years, especially at puberty. It should be noted that elderly people with cataracts may also become myopic.

Myopia is usually corrected with glasses or corrective lenses . A shortsighted person who is not being treated risks eye fatigue and / or severe headaches.

The laser operation

It is possible for twenty years to have surgery to permanently cure myopia . Especially since innovation in laser surgery continues to go further. Among these novelties: the femtosecond laser . Programmed, it replaces the human hand and performs the operations itself. Its major advantage is to reduce the duration of the operation to only 10 minutes, but also to limit the surgical trauma. This technique is currently used at the European Hospital in Marseille, for example.

This technology adds to the different types of laser operations that already exist. Surface laser, laser lasik, myopic implant … The choice is made according to many criteria, among which the age, the thickness of the cornea, the size of the pupil, the professional activity, etc.

Always further in innovation

For those who would like to avoid laser surgery, sometimes considered too invasive, there are other innovative techniques for correcting myopia. It is for example possible to reshape his cornea – too curved in the case of myopia – thanks to rigid lenses, which will flatten during the night. This is orthokeratology . For that, it is enough to wear his lenses at night to wake up with corrected sight, A disadvantage all the same: one must not forget to wear them during his sleep, on pain of finding his sight of myopic the next morning.

A revolution for those with multiple vision disorders – myopia and presbyopia, for example. There are now glasses that can see from near and far on the entire surface of his glasses with liquid crystals. And so, avoid wearing multifocal lenses (which have two to three correction zones). This is the concept of DeepOptics .

And given the increase in the percentage of myopes looming in the next 30 years, innovation is not likely to stop;)
