laser surgery

In order to actually comprehend the effect of laser eye surgery, we first ought to consider the vision anomalies that it treats. It is a general belief that common refractive disfunctions, for example myopia, hyperopia and astigmatism, are down to certain irregularities in the shape of the cornea. Due to such problems, light rays entering the eye don’t fall precisely on the retina (a layer of light sensing cells) so resulting in poor vision. LASIK is a surgical technique that intends to rectify these irregularities by reshaping the cornea.
