The problem: impared vision
Not too long ago, people with poor sight were compelled to seek help with glasses and contact lenses - aids which do nothing to correct the root problem of impaired vision.
The problem lies in organic defects in the eye's structure, which prevent the light rays from focusing correctly on the surface of the retina. While glasses merely attempt to change the way the light enters the eye, a far more intelligent solution has been around for quite some time.
Refractive surgery with LASIK is able to correct impaired vision in the eye itself.
Ametropia

Nearsightedness (Myopie)
Myopia – the medical term for nearsightedness – is a refractive error that results in distant objects being blurred, while near objects remain clear. It is one of the most common eye disorders.

Farsightedness (Hyperopie)
Farsightedness, also known as hypermetropia results in blurry vision when objects are near whereas objects in the distance remain clear. Farsightedness can become a hindrance in life as reading without glasses is hardly possible and may cause headaches.

Astigmatism
Astigmatism can significantly interfere with your daily life. Your eyes may have so much trouble focusing on objects that they become fatigued, which then leads to other painful symptoms. Astigmatism often occurs in combination with nearsightedness or farsightedness, requiring a prescription for glasses and/or contact lenses.
