What is refractive surgery?

This technique is carried out on our Refractive Surgery Unit.

Myopie

Blurry image due to a refractive defect

Refractive Surgery corrects refractive errors, reduces or decreases the dioptric power of the eye.

The most common refractive errors or problems with focusing are nearsightedness (Myopia) and farsightedness (Hyperopia), which occur when light rays refracted by the cornea and the lens do not focus on the retina, resulting in blurred vision. Astigmatism is another common refractive error in which the eye is not uniformly shaped, resulting in distorted images.

The cornea and refractive defects

The cornea is responsible for 80% of the refractive power of the eye. By modifying the curvature of the cornea refractive errors can be corrected. This is the basis of current refractive techniques such as LASIK.

Laser surgery for nearsightedness and farsightedness: LASIK

In LASIK, the surface of the cornea is reshaped using the Excimer beam. The laser is applied in the inner cornea after pulling back a thin flap of corneal tissue, which is replaced to its initial position when the laser application is finished. Stitches are not necessary because the layers of the cornea are naturally "sticky" and will adhere to one another once the flap has been put back.

At Iradier Eye Clinic we improve on LASIK using Intralase

To improve the accuracy and safety of LASIK, in our clinic we use the new Intralase technique.

The LASIK with IntraLase technique is based on the use of two different lasers, Excimer and Femtosecond. Our medical team has pioneered the use of this technique.

In our Youtube channel you can find videos showing the technique of LASIK surgery using Intralase   as done by Doctor Iradier.

How is the surgery like for the patient?

Normally the surgical procedure is completed in a few minutes. There is no pain and only minimum discomfort. Anesthetic eyedrops are administered to numb the eyes. No postoperative eye patching is needed. Visual recovery begins immediately after the operation.
