Refractive Errors
The three most common refractive errors that New York residents seek to have surgically corrected are nearsightedness, farsightedness and astigmatism.
Nearsightedness (Myopia)
Nearsightedness occurs when the cornea is irregularly shaped so that the light entering the eye focuses in front of the retina, instead of directly on it. You will know you are nearsighted if you can see well up close, but distant objects are fuzzy.
LASIK, PRK and other refractive procedures correct nearsightedness by reshaping the cornea so that the focal point is on the retina.
Farsightedness (Hyperopia)
Farsightedness occurs when the cornea is irregularly shaped so that the light entering the eye focuses behind the retina, instead of directly on it. Patients that are farsighted have trouble seeing objects up close and must often squint to see them clearly.
Many New York residents suffering from nearsightedness have sought LASIK surgery as their choice of laser vision correction.
Astigmatism
The most common of all eye disorders, astigmatism occurs when the eye is shaped more like a football than a basketball, which is its natural shape. This odd shape causes the light to focus on two points of the retina, rather than one.
Astigmatism is often accompanied by either nearsightedness or farsightedness. LASIK will treat astigmatism with one of the other conditions simultaneously. |
