Laser eye surgery
Laser eye surgery treats astigmatism, hyperopia, and myopia, other varieties are PRK and SMILE. LASIK is the most common but not the only good choice.
All these procedures change the cornea’s shape, so light can focus on the retina, fixing how the eye bends light improves vision.
How does this procedure operate?
Before LASIK the surgeon creates a thin flap in the eye using a femtosecond laser or a microkeratome blade. The corneal tissue under is reshaped with an excimer laser following flap lifting. Like a natural patch, the flap moves to a new position with changes in shape.
As an option to LASIK, PRK removes the epithelium from the corneal surface instead of making a flap. The cornea can change form with the same excimer laser and the epithelium grows over time.
With SMILE, a very small piece of corneal tissue called a lenticule is taken out through a very small cut, so there is no need for a flap. If you are considering how much laser surgery for eyes usually costs, it depends on the on the operation and clinic.
Is having laser eye surgery safe?
Most people think laser eye surgeries are safe especially when done by expert laser eye surgeons who use advanced technology. The treatments work very well; about 96% of people with LASIK have 20/20 vision or better.

Pre operative exams are very important for figuring out who is eligible. People with thin corneas, certain eye diseases or unstable vision might not be the best options, a careful consultation can help ensure the best result.
