What is myopia?
Myopia is a vision disorder in which the person sees objects blurry from a distance, because the lens is too curved, therefore too convergent, and the light rays meet in front of the retina. In other words, the myopic person sees less well from a distance than up close. This can be corrected by glasses, contact lenses or by refractive surgery. 26% of the world's population is myopic, with a clear tendency to increase, in industrialized countries we sometimes even speak of a myopia epidemic.
Myopia Correction
There are several ways to correct myopia:
1- Correction by wearing glasses. The greater the correction, the thicker the lens. Constantly wearing glasses can be restrictive: discomfort during sports, narrowed field of vision, etc.
2- Correction by wearing contact lenses, which offer a clearer field of vision than glasses and greater comfort. Before you can wear contact lenses, an ophthalmological examination is necessary, with preliminary fittings.
3- Myopia correction by refractive surgery is now particularly advanced and effective.
Provided that you first verify your eligibility for eye surgery to correct myopia, a preliminary eligibility examination is required to check your vision, the thickness of your cornea, and many other criteria.
High myopia can also be corrected very well with LASIK in some cases, up to 10 or 12 diopters (even when associated with astigmatism) if the cornea is sufficiently thick.
Myopia can therefore be corrected with LASIK, FEMTO LASIK, PKR, Trans PKR, and lenticular extraction, but sometimes none of these first-line techniques are applicable.
It is necessary then turn to other surgical solutions such as the implantation of an implant in front of the lens or an artificial implant replacing the latter, but this is a more serious operation, equivalent to a cataract operation.
Operation procedure
Laser eye surgery to correct myopia and other visual defects is a very quick and painless procedure (except with the PKR/TransPKR technique, where postoperative pain is often severe for the first two days). Vision is restored very quickly, and myopia correction is often immediate after the procedure. The results are long-lasting. Regarding the risks associated with laser eye surgery, it is important to know that there is no such thing as zero risk in surgery. However, by taking all necessary precautions regarding sterilization of equipment, hygiene conditions, and careful selection of operable and non-operable patients, all risks associated with the operation can be significantly reduced.
