Laser refractive procedures
What exactly is refraction?
Refraction is the optical phenomenon in which light’s orbit direction is changed when it passes through a transparent material to another. Many people compare the human eye with a photographic camera. Cornea, iris and crystalline lens compose a photographic camera focusing system and the retina in fact is a photosensitive film for capturing visual stimuli.
What exactly are laser refractive procedures?
Undoubtedly, excimer laser refractive procedures are the world’s most widespread eye surgical procedures for correcting common and well known refractive errors (myopia, hyperopia, astigmatism), providing really excellent results. Their philosophy was based on the fact that alterations of corneal shape and curvature are able to change the refractive power of the eye (light rays that focus on retina without further correction, no need for spectacles or contact lenses). Excimer laser is applied to corneal tissue achieving reshaping and curvature change through ablations, thus every image reflection is formed clearly on the retina.
