US researchers have invented an alternative to the correction of vision using Lasik; It is the reform of the cornea using a weak electric current instead of cutting it with laser, which is the procedure that is hundreds of thousands of thousands of thousands of annually, and not without risks and side effects. The study, presented at the annual meeting of the American Chemical Society, showed that this technology; It is known as the electrical-mechanical reinstatement, and it has succeeded in changing the form of rabbits in the laboratory to correct the concession, without the necessary surgical incision or removal of tissues. The Lasik technology is currently being used for the reform of the cornea, which is the transparent layer at the front of the eye, with the aim of correcting the way to break the light to focus accurately on the retina. The process is performed using a delicate laser beam to remove micro -amounts of corneal tissues, which change the extent of their curvature according to the lack of vision that must be corrected, whether shortened, no visible or deviation; Known as astmaqat. Although Lasik process is safe and common, it can lead to some side effects that differ from one patient to another, most of which are due to the nature of the procedure based on the cut and removal of part of the corneal tissue. In the Lasik process, problems such as the missing or excessive correction of the vision can occur if an inaccurate amount of tissue is removed, and most importantly of these effects are dry eye, as the process affects the nerves responsible for stimulating the secretion of tears, which can be the moisturizing the surface of the eye for a period that can stretch, as See whether halos to see or stimulate halos or halos to stimulate the change in the curvature of the cornea and irregularity its surface. Problems such as a missing or excessive correction can occur if an inaccurate amount of tissue is removed, which sometimes requires re -intervention; There is also a less general risk of weakening or diluting the cornea due to its removal, which in rare cases can lead to the deformation of the cornea or the poor ability to withstand eye pressure. As far as the new technology is concerned, it depends on the reinstatement of the electrical-mechanical on a principle that is completely different from the traditional Lasik; The cornea, rich in collagen and water, is formed when exposed to a low electrical tension that changes the pH in the tissue, leading to the relaxation of bindings between collagen fibers. During this brief moment of flexibility, a platinum lens is especially placed on the eye that works as a pattern for the required form, so that the cornea takes its new curvature, and with the return of acidity to its natural level, the links are closed again, so that the cornea retains its modified form without the necessary pieces or removal of the tissues. The researchers performed preliminary experiments on 12 rabbit eye balls, and they placed platinum lenses designed to correct the perception of the corneas in a salt solution that mimics natural tears, and after only one minute of applying a low electrical tension, the curvature of the cornea to comply with the form of the form, and in 10 eyes simulated. The tests showed that the cells remained intact thanks to the exact control of chemical changes, and additional experiments indicated that the technique could help remove the corneal output due to some chemicals, a condition that is currently not treated, except for a complete corneal transplant. Despite the encouraging results, the researchers emphasize that the work is still at the beginning; The next phase contains accurate experiences on live rabbits, to evaluate the long -term response and the scope of the technology suitable for correcting different types of vision defects, such as the length of the view and deviation; Istatazat. But the road is not paved; Funding barriers can delay the transition to important experiences. However, the leader of the research team, Michael Hill of Oxidental College in the United States, believes that if it reaches clinics, it will be much cheaper than Lasik, easier to apply, and perhaps the opposite if necessary. While Lasik is still the most common option for visual correction, the technique offers the electrical-mechanical weather, another vision; Corneals recover without surgery, without laser, and perhaps without the known side effects. Although the road is long before it applies to people, the initial results open the door for a new generation of safe and simple vision correction methods.
