PRK/LASEK uses the least amount of equipment to perform laser eye surgery, which is often reflected in its more economical price. This surgery is popular in some countries, however in others PRK/LASEK is infrequently performed unless other methods are unsuitable to the eye’s conditions.
These procedures remove a thin cell layer from the top of the eye to prepare the eye for actual procedure: reshaping the cornea with the laser. This surgery may be an option for those who are not eligible for LASIK or want to avoid a flap.
LASIK is the most common method to correct nearsightedness, astigmatism, a combination of the two or farsightedness. Over 35 million people in the world have had their vision corrected by it since the 1990’s.
It treats refractive errors by opening the top layer of the eye and re-shaping tissue.
SMILE is a minimally invasive, flapless treatment quickly gaining importance and offered in more and more clinics. It is used so far to correct nearsightedness, astigmatism or a combination of the two.
SMILE corrects refractive errors without creating and opening a flap in the cornea – a small incision in the cornea is used to extract excess tissue. This high-precision procedure is the latest development in refractive laser technology.
