After laser correction, vision improves due to the fact that the laser creates a new shape of the cornea – the “natural lens” of our eye, as a result of which it begins to refract light rays in a different way, they are focused on the retina and the image becomes clear.

During the excimer laser correction according to the LASIK method, the upper layers of the cornea are not affected, and the optically distorted areas are evaporated by the laser beam from the middle layers of the corneal tissue. As a result of such exposure, the shape of the cornea acquires optical parameters that are individual for each patient. This avoids postoperative clouding of the cornea and a painful rehabilitation period. Vision is restored in the shortest possible time.

Limits of application of laser vision correction using the LASIK method:

• Myopia (.short-sightedness) up to −15.0D
  (the doctor focuses on the individual characteristics of the eye);
• Hyperopia. ( long-sightedness) +6.0D;
• Astigmatism ± 3.0D.

Individual Approach:

The modern LASIK technique (LASIK) implies an individual approach to the treatment of diseases of the organs of vision. Before direct vision correction with a laser beam, doctors conduct a thorough examination, which allows to identify the degree of the disease. All data obtained as a result of diagnostics are entered into a computer, which calculates the parameters of laser exposure to the inner layers of the cornea of the eye. This allows you to achieve maximum accuracy of vision correction.

Stages of laser vision correction using the LASIK method:

• Anesthetic drops are instilled into the patient’s eye (anesthesia or anesthetic injections are not used). After the anesthesia has worked, a an eyelid speculum is used. It keeps the eyelids from involuntary blinking.
• The patient is asked to look at a luminous dot in the device to center the position of the eye.
• A special device – a microkeratome – creates a flap from the surface layers of the corneal tissue with a thickness of 130-150 microns, and then folds back, opening up access to the deeper layers of the cornea for the laser beam.
• The laser beam vaporizes part of the cornea, forming its new surface.
• The flap is returned to its place and fixed by collagen – the cornea’s own substance.
• No sutures are required. Restoration of the epithelium along the edge of the flap occurs independently.
• After the laser correction is completed, the cornea is washed with a special solution. The patient is given anti-inflammatory drops.
• Then the correction is made in the same way on the second eye.
