Lasik surgery is indicated to treat vision problems as up to 10 degrees of myopia, 4 degrees of astigmatism or 6 of hypermetropia, it takes only a few minutes and has a great recovery. This surgery is to modify the curvature of the cornea, which is located at the front of the eye, improving the way the eye focuses images, allowing better vision

Farsightedness is the difficulty in seeing objects closely and happens when the eye is shorter than normal or when the cornea (the front of the eye) does not have sufficient capacity, causing the image to form after the retina.
