Laser Eye Surgery removes microscopic amounts of corneal tissue to either reduce or increase the gradient of you cornea so that light bend correctly and focus clear images onto the retina.īecause the exact amount of excess corneal tissue is removed, vision is immediately corrected and you can resume to your normal routine, usually after 24hours. Your eye doctor may also do a corneal topography scan, which helps find imperfections and distortions on the corneal surface. A keratometer measures the curve of your cornea. How does Laser Eye Surgery reshape my cornea? We use lenses to help us see objects everyday. It works by shining a light into the eye and measuring how it changes as it bounces off the back of the eye. Sometimes astigmatism presents itself along with either myopia or hyperopia. Coloboma of the iris is a hole or defect of the iris of the eye. Light cannot bend correctly and contribute to blurred vision. With hyperopia, far away objects are not an issue, but you have difficulty making out near objects.Īstigmatism: If your cornea isn’t spherical and is instead oval, then you have astigmatism, which usually manifests during childhood. Hyperopia: In the case of hyperopic eyes or long-sightedness, the eye can be too short or else the cornea is too flat which contribute to light being focused beyond the retina. Objects up close are perfectly clear but anything in the distance appears blurred, hence the term shortsightedness. Several months into infection, these growths will only cause more damage, with those along the mouth and jaw growing to resemble a second row of teeth, jagged and misshapen in such a way that they force the mouth constantly agape and protrude from the eye sockets to eventually pierce the eyeball, causing extreme vision damage and blindness. With astigmatism, the eye is egg- or oval-shaped. Myopia: In myopic eyes either the eye itself is too long or else the cornea is too steep which cause rays of light to fall short when they reach the back of your eye. To understand astigmatism, it is helpful to think of the normal eye as evenly rounded, like a basketball. In a normal eye with perfect 20/20 vision, the cornea is a perfect spherical shape, but a refractive error indicates a misshapen cornea.
