My refractive error is about -4, in 1.5 year I’m going to apply to a fire-fighter officers’ school where even smallest refractive error is unacceptable. Which method is the best, given the above context? Can the correction be repeated?

The refractive errors reported by you are, by all means, possible to correct. Our equipment is able to correct errors from -14D to +6D and astigmatism (up to 6D). You are asking which method is the best. Each method is good and effective, each treats visual impairments. The methods differ in terms of preparation of the cornea for the proper operation. The methods in which a flap of the cornea is created (LASIK, SBK LASIK) the patient does not experience any discomfort on the next day after the surgery. After surgeries during which the corneal epithelium is removed (PRK, TransPRK, LASEK, Epi-LASIK, EBK), the patient experiences pain for 3-5 days after the surgery. The suitable method is chosen after the qualifying examination, during which, among other tests, pachymetry (measurement of the thickness of the cornea) is performed. LASER VISION CORRECTION surgeries are usually performed once in a lifetime. In rare cases (depending on individual characteristics), however, when the error is very large or a mixed astigmatism occurs, after the effects stabilize (6 months), the remaining error can be operated again. Each method allows for a reoperation, providing the cornea is thick enough.
