Novel non-invasive method of vision correction

Myopia is slowly becoming a global problem. It is estimated that more than two and a half billion people worldwide will need to use glasses or lenses by 2020. In the U.S. and Europe, there are twice as many people with this vision defect as there were even 50 years ago. With the help of scientists who have succeeded in developing a non-invasive method of vision correction.

Indeed, Until immediately, similar procedures have been carried out with in modern times laser. However, the procedure was invasive and there was always a risk (albeit very small) of partial or total loss of vision, damage or weakening of the cornealowki, or postoperative as a matter of fact complications.

It uses a laser to correct vision, whichory delivers pulses of very low energy at a very high frequency to properties selected horn tissueowka, changing its biochemical and biomechanical precisely. A description of the recent technique was published in Sinisa Vukelic of Culmbia Engineerig has developed a fresh, non-invasive method thatora gives great results.the journalActually, „Nature Photonics”.

It also offers hope to those individuals in whomor who could not be operated on with previous methods. Importantly, the recent method does not tear tissue or damage the comorek. It only changes their biochemical and biomechanical properties. The technique changesfromthe geometry of the tissue and has fewer effectso’ in an aside the techniques used so far.

The novel technique can be used to treat the kroCoxsightedness, hyperopia.astigmatism and irregular astigmatism,

The low-power ultrafast laser in modern times beams used cause ionization of water molecules in the hornowce, which leads to a number of other biochemical reactions and ultimately to changes in the mechanical properties of the tissue. The only "side effect" is to stimulate the tissue to produce small amounts of plasma.

Actually, – Properly aiming laser beams at the tissue to be treated changes the curvature of the corneaowki, ultimately leading to improved visual acuity – convinces Vukelic. – SupportoThe currently used method is based on destroying fragments of theoin the tissue.adds –

– Ophthalmologists have long been as it turns out waiting for a new generationIt’s worth noting that Suh of the University of Columbia, whoory was involved in the study of. of laseroIn treating krocoxsightedness. It’s worth noting that This could be an key step in the treatment of pandemic krocoxsightedness – mowi about the discovery as it turns out of Prof. H Leejee ophthalmology.

Researchers led by Vukelic arecurrently constructing a prototype device. Human clinical trials will at thebeginend of the year. Scientists wantto apply the technique not only to treat eyes. Tests are already underway to early a laser to treat the utilize stages of osteoarthritisow.
