Refractive Surgery (LASIK)

Refractive surgery (LASIK) is a procedure to improve sight and eliminate the need for corrective or contact lenses. The eye functions as a camera with two lenses, the cornea and crystalline, which focus the image upon the retina (similar to camera film). The process to manage light and image is called refraction. For images to be focused properly, both lenses must offer a clear image. Should the image be projected before or after the retina, it appears inaccurate. Refraction conditions include short-sight, far-sight and astigmatism. Currently, there is the possibility of using a laser treatment called EXCIMER to correct refraction problems. Each patient's refraction situation is unique and, like a digital imprint, calls for a personalized treatment or LASIK which is performed using FRENTE DE ONDA technology.

Benefits
Limited use of corrective lenses.

Technical description
It requires topical anesthesia.  Depending on the patient's needs, a small corneal flap is used to apply the excimer laser.

Time
Surgery takes approximately 10 minutes.
