LASIK Eye Surgery Information

Refractive Myopia

Refractive errors are experienced by an estimated 1.8 billion to 2.3 billion people worldwide. Nearsightedness, the most common error (myopia) is a vision defect in which distance objects appear blurry because the image that enters the eye is focused in front of the retina rather than on it.

Hyperopia Refractive Errors

Farsightedness (hyperopia) is a vision condition in which distance objects appear clearer than near objects due to the eye being too short, thus causing the image entering the eye not to be clearly focused on the retina.

Astigmatism Refractive Errors

Astigmatism is a vision condition caused by the cornea of front surface of the eye to be shaped more oval (or oblong) like an egg or football rather than spherical (or round). This causes light rays to focus in two separate points on the retina rather than one causing a distorted and blurry image at both distance and near.

Presbyopia Refractive Surgery Correction

Refractive Presbyopia is a vision condition caused by the aging process in which the natural lens inside the eye gradually losing its flexibility and results in blurry vision for reading and near work.
