There are two commonly used methods of performing laser myopia surgery: LASIK and PRK. Both have the same objective, which is to remodel the cornea, making the light that reaches the eyes, responsible for the formation of the image, to be able to focus on the retina, which does not happen in myopia – the refractive error consists of focusing the light before it hits the retina, resulting in a blurry image for distant objects.

The LASIK method is the most advanced and is indicated for patients with a certain corneal thickness, making it more resistant to the process. A small cut, about 0.1 mm, is made in the patient’s cornea in this procedure. The part that underwent the cut is lifted so that the laser has direct access to the cornea and, thus, it can remodel it properly, according to the existing degree.

The PRK method is indicated for patients who have a thinner cornea, which prevents the small cut of the LASIK method from being made. Here, the epithelial tissue, which is a thin membrane covering the cornea, is completely removed, and thus the laser has access to the cornea.

The laser used in both types of surgery is the same. Before starting both procedures, local anesthesia is applied with eye drops; however, there may be cases in which the patient is lightly sedated. In the end, a contact lens is applied to protect each operated eye. The surgical process is painless and doesn’t take long, lasting about 20 minutes in both eyes.

How Much Does Myopia Surgery Cost?

Custom LASIK or PRK surgery tends to cost more than regular LASIK or PRK surgery, and the price of the surgery will vary depending on the clinic chosen. It is essential to add up all the costs, such as evaluation appointments, eye exams, and the surgery, which involves the operating room, medical staff, and materials.
