If you are over 18 years old, have a stable refractive error in the last two years
Corneal thickness is not less than 450 μm, and the refractive error is not more than 1,200 degrees of myopia
Far-sightedness is not more than 600 degrees, and astigmatism is not more than 600 degrees, then you can have the operation
If the myopia is less than 600 degrees, then you can wear Wilmar keratoplasty lenses.
If your myopia is less than 600 diopters, and you are under 18 years old, you can wear Wilmar corneal reshaping lenses
Keratoconus lenses require a detailed examination, and it is very important to check the corneal topography
So, you should try to go to a big optometric center.
