The eye is a complex optical system by which we get the most information from our environment. Light rays reflected from objects all around, entering the eye refract and focus on the retina. Such is prechupvatelnata ability of normal (emetropichno) eye. But this system has its imperfections in refraction we call refractive errors such as nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. They corrected with glasses, contact lenses, and nowadays with laser treatments. Laser correction using excimer laser is the most advanced and successful refractive manipulation.
What is laser correction?
Laser vision correction is a procedure designed to eliminate the dependence of man on glasses or contact lenses. The eye surgeon using the excimer laser adjust the shape of the cornea, thus eliminating refractive errors of the eye (nearsightedness, farsightedness and astigmatism).
Is it possible to make my laser vision correction?
Every candidate for laser correction must meet several mandatory requirements. He / she must:
– Be at least 18 years;
– No change in bifocals last one year;
– Be willing to get rid of glasses.
Patients who have an eye infection or injury, and certain degenerative, and autoimmune diseases are not suitable for this procedure.
The most accurate and reliable answer to the question whether you can undergo this medical procedure will give your ophthalmologist after a comprehensive eye examination in the Eye Clinic “Day”.
Itself laser correction
There are two main types of refractive laser correction: surface correction (PRK / LASEK) and correction forming flap (LASIK). Each of these procedures can be performed as standard or customized correction.
PRK (photorefractive keratectomy) / LASEK (Laser Assisted Epithelial Keratomileusis) is a type of surface correction in which excimer laser evaporates at the surface of the corneal stroma. Different is the way that was peeled corneal epithelium. In LASEK the epithelium moved after laser ablation returned to his place. In PRK the epithelium is removed completely and requires a longer period for his full recovery.
LASIK (Laser-Assisted In situ Keratomileusis) e lamellar refractive laser manipulation in which excimer laser ablation performed in lamellar corneal flap. Lamellar flap is made with microkeratomes or a femtosecond laser.
To determine whether a patient is a good candidate for laser correction with excimer laser, you need to make a thorough eye examination. If you wear soft contact lenses should stop putting them two weeks before the initial examination, and if you wear hard contact lenses – four weeks before the examination, and during this time wearing glasses. This is done in order to restore normal corneal status and not to compromise the research.
On the day of the procedure
On the day of manipulation we recommend not to use makeup, perfume, deodorant and face cream or any cosmetics and detergents on your face. The laser correction lasts about 10 minutes, and the entire stay at the clinic is about 60-90 minutes.
Studies show that over 95% of patients the result is excellent and does not need further adjustment. In very rare cases (at higher diopters) may need to wear glasses, but with a much smaller diopter or will be offered re procedure of the same eye.
The decision to perform laser correction is taken from the patient based on better information. Successful laser correction is based on professionalism, responsibility and cooperation between the patient and the doctor.
