LASIK eye surgery can be performed on people with the following vision problems:
It is a refractive surgery which changes the shape of the cornea which is the dome shaped transparent tissue in the front of the eye. The aim of LASIK eye surgery is to give sharper and clearer vision by bending the rays of light so that it focuses exactly on the retina.
The rays of light focuses in front of the retina and it blurs the distant vision due to the sharp curve of the cornea or the eyeball being slightly longer than normal. The objects which are far away are not as clear as the objects which are closer.
When the light does not focus on the retina but behind it due to a cornea which is flat or the eyeball which is shorter than average than the near vision becomes blurry and sometimes even the distant vision gets blurred.
Astigmatism occurs when the cornea flattens or curves unevenly and due to which the focus of distant and near vision gets disrupted.
To correct your vision the eye doctor will recommend different options such as contact lenses or glasses before he recommends Lasik eye surgery.
