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 when playing 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 tests.
3- Myopia correction by refractive surgery is today particularly advanced and effective.
On condition of first verifying eligibility for eye surgery to correct myopia, a preliminary so-called eligibility examination is required, in order to check your eyesight, the thickness of your cornea, and many other criteria.
High myopia is also very well corrected by Lasik in certain cases up to 10 or 12 diopters (even associated with astigmatism) if the cornea is sufficiently thick.
Myopia can therefore be corrected either by Lasik, FEMTO Lasik, PKR, Trans PKR and lenticular extraction, but sometimes none of these first-choice techniques are applicable.
It is then necessary to 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 for the correction of myopia and other visual defects is a very quick and painless operation (except with the PKR/TransPKR technique where post-operative pain is often painful for the first 2 days). Vision is recovered very quickly, often the correction of myopia is immediate after the intervention. The results are long-lasting.
Regarding the risks associated with laser eye surgery, you should know that in surgery, zero risk does not exist, but by taking all the necessary precautions regarding the sterilization of equipment, hygiene conditions, sorting in the choice of operable or non-operable patients... we can greatly reduce all the risks associated with the operation.
