Myopia is a visual impairment. The perception of an object is fuzzy from afar and clear when close up. In a healthy eye, the image of a distant object is formed on the retina. The myopic eye is too long and / or its cornea too bulging however, and the image is formed in front of the retina. Focus is therefore blurred for objects located far away.
Myopia affects 20 to 30% of the world’s population, or around 2 billion people. According to the French Society of Ophthalmology, this figure is likely to increase by 2050. This pathology could therefore affect half of the world’s population. This phenomenon is not only genetic but is probably due to contemporary lifestyles. Indeed, time spent in front of screens, reading and lack of light may be involved. To correct myopia, our ophthalmic surgeons perform laser surgery.
The laser operation to correct myopia consists in reshaping the part of the cornea that deals with distance vision. Focusing will then take place correctly on the retina.
Lasik is the most widely used laser operation to correct the myopic eye. Indeed, this technique, performed in a few minutes, is very effective and is completely painless. Furthermore, in cases of very pronounced myopia, refractive surgery is the best solution. This involves placing a lens inside the eye called an intraocular implant.
Myopia, like other visual disorders, is expressed in dioptres (unit of optical power). Lasik corrects myopia from -1 to -12 dioptres.
Thus, we can consider myopia in the following way:
|from -1 to -3 dioptres|
|from -3 to -6 dioptres|
|more than -6 dioptres|
