SURGICAL TREATMENT OF AMETROPY IN OPHTHALMOLOGY CLINIC MC NAIRI

SURGICAL TREATMENT OF AMETROPY IN OPHTHALMOLOGY CLINIC MC NAIRI

Ametropia from Greek word “ametros” means disproportionate («ametros»). This pathology is a consequence of the discrepancy between the refractive forces of the organ of vision and the length of the optic axis. Currently, termin ametropy may include any refractory function deviation - myopia, hyperopia, and astigmatism. In the case of ametropia, the vision in far or close distances is decreased, depending on the type of refraction violation.

Which method of correction of ametropy is preferable: glasses, contact lenses or surgical correction?

It is completely wrong to oppose these methods; each of them has its own indications. It all depends on the information of the detailed diagnostic examination of the eyes, the degree of ametropy, the stability of this information, the presence of concomitant eye diseases, chronic diseases, and the age of a person, his profession and the requirements of a person to its visual function.

 Perfectly, when the ophthalmology clinic has a full range of treatment services:

  • diagnostic and measuring equipment;
  • production of any complexity of glasses, with any modern coatings that improve the quality of optics;
  • operating room for laser correction;
  • operating room for laser surgery (if indicated) laser coagulation of the retina and retinal detachment risk reduction;
  • operating room for lens replacement;
  • a room of special methods of visual training.

This allows to choose the method of correction, taking into consideration all individual characteristics of the patient.

The glasses remain the most common method of correction, and they accompany the person with ametropia from childhood (when the glasses provide proper development of a full binocular vision) to old age (to correct the naturally developing age-related hyperopia).

In addition to spectacle correction in the Ophthalmology Clinic of MC Nairi correction of ametropia is carried out by laser surgery. In our clinic refraction surgery are carried out with the use of the advanced, the only in our region fifth generation laser manufactured by ALKON. Surgeons of the center have passed qualification in the leading clinics of America, Germany, Russia, the Ukraine.

In Ophthalmology Clinic of MC Nairi there are two types of laser surgeries: photorefractive keratectomy (PRK) and Lasik.

Photorefractive keratectomy (PRK) is a non-contact exposure with the excimer laser on the surface layers of the cornea, without affecting other structures of the eye. At the same time, the laser, working in the scanning mode, "smoothes out" and "simulates" its surface. Laser actions are controlled by a computer program, which completely eliminates any errors during the surgery. In practice, this can not even be called a surgery in the usual terms, because the ophthalmic surgeon does not directly interact with the tissues of the eye.

The LASIK method of laser correction of vision appeared in 1989. Today it is the most popular on over the world. Medical centers and clinics carry out LASIK procedure in 45 countries. Over the past decade, more than 15 million corrections have been carried out in all over the world. LASIK is a combination of microsurgical exposure and excimer laser technology. In the course of laser correction, a special device is used - microkeratome, which previously creates a flap of corneal tissue that is bent, and laser exposure is already made on the inner layers of the cornea.

 After laser correction, vision is better due to the fact that the laser creates a new shape of the cornea - the "natural lens" of our eye, so that it begins to refract light rays differently, they focus on the retina and the image becomes clear.

In contrast to the PRK method, during the excimer laser correction with the LASIK procedure, the upper layers of the cornea are not affected, and the evaporation by the laser beam of the optically distorted sections occurs from the middle layers of the corneal tissue. As a result of that exposure, the shape of the cornea acquires optical parameters, individual for each patient.
