Surgery of the Eye to Correct Refractive Errors

The clarity of the vision depends on that so well the cornea and the lenses leave that the rays of light fall in the retina. The rays of light have to be refracted (doubled) to be focused in the retina. The retina is the sensitive nervous layer to the light that covered the back of the eye, that creates impulses since the rays of light that are then envoys through the optic nerve toward the brain. If the form of the cornea or of the eye they are abnormal, the vision can be returned blurry since the light does not fall in a way appropriate in the retina. To what we call an error refractive, said abnormal forms of the cornea can be corrected often through the refractive surgery, which, at the same time, corrects the problems of the vision The refractive errors can include the myopia, the farsightedness (farsightedness), the astigmatism (a cornea of irregular form that causes the blurry vision), and the presbyopia (that is seemed to the farsightedness, a condition that causes the hardening Of the lenses). The goal of the majority of the refractive surgeries of the eye is to reduce or to eliminate the dependence of a person of its eyeglasses or of its contact lenses. The refractive surgery of the eye is not appropriate for all the people. A they determined type of surgery can be better for a person that for another. Always consult with its doctor for its diagnosis and to discuss that type of surgery, if there are it, could be appropriate for you. Various types of surgical procedures exist to correct refractive errors, including, but without be limited to the following: Surgery queratomileusis laser in situ (its acronym in English is LASIK). Queratectomía fotorefractiva (its acronym in English is PRK). Queratomía radial (its acronym in English is RK). Queratomía astigmatic (its acronym in English is AK). Queratoplastia lamelar automated (its acronym in English is ALK). Queratoplastía thermal with laser (LTK). Queratoplastía conductive (CK). Ring intracórneo (Intacs).
