In order to truly comprehend the effect of laser eye surgery, we must first consider the vision anomalies that it treats. It is a general belief that common refractive errors, such as myopia, hyperopia and astigmatism, are attributable to certain irregularities in the shape of the cornea. Due to such anomalies, light rays entering the eye dont fall exactly on the retina (a layer of light sensing cells) thereby resulting in unclear vision. LASIK is a surgical procedure that aims to rectify these irregularities by reshaping the cornea.
LASIK restores visual acuity through precise ablation of the corneal tissue with the aid of a high precision laser, an excimer laser, which is a cool laser that precisely carves the cornea without heating or damaging the surrounding tissue. Once reshaped, the cornea enables the desired accurate refraction, since the light rays now fall precisely on the retina.
Laser eye surgery imparts enhanced visual acuity, without the need for corrective lenses. With the superlative technology at its disposal, laser eye surgery provides excellent results that are rather impressive. An estimated 98% of patients are within 1 diopter of their...
