Description

Nearsightedness (myopia) is a common vision condition in which a person can see objects near clearly, but objects farther away are blurry. Nearsightedness may develop gradually or rapidly, often worsening during childhood and adolescence. Nearsightedness tends to run in families.

Causes an Risk factors

If a person is nearsighted, the light rays that enter each eye are focused in front of the retina, instead of on the retina. This causes blurry images.

Diagnosis and Treatment

Lasik eye surgery, commonly referred to simply as laser eye surgery, is a type of refractive surgery for correcting myopia, hyperopia, and astigmatism. Lasik is performed by ophthalmologists using a laser. This surgery reshapes corneas to sharpen vision.

Lasik is similar to other surgical corrective procedures such as photorefractive keratectomy (PRK), (also called ASA, Advanced Surface Ablation) though it provides benefits such as faster patient recovery. Both Lasik and PRK represent advances over radial keratotomy in the surgical treatment of vision problems, and are thus viable alternatives to wearing corrective eyeglasses or contact lenses for many patients. ...
