What Eye Conditions Does LASIK Treat?
LASIK surgery can correct three types of refractive errors:
Myopia (Nearsightedness) – Myopia occurs when the eyeball is slightly longer than usual. This causes light rays to focus at a point in front of the retina, rather than directly on its surface. Patients who are nearsighted have difficulty seeing objects that are at a distance. LASIK surgery corrects myopia by flattening the cornea so that light entering the eye focuses on the retina rather than in front of the retina.
Hyperopia (Farsightedness) – Hyperopia occurs when the image formed by the focusing mechanism of the eye is behind the retina. This condition is caused by an eye that is shorter than normal, or a cornea that’s not as curved as it should be. Patients who are farsighted have difficulties seeing objects that are close, and typically have trouble with reading or viewing any item up close.
Astigmatism – Astigmatism is a common condition caused by an imperfection in the curvature of the cornea or lens of the eye. When the cornea or lens is unevenly steepened, it can result in objects having an irregular focus. This very a common refractive eye disorder and can be found on its own but it can also accompany hyperopia and myopia.
