Lasik Surgery: Benefits and the Risks

If we talk about the eye surgeries then Lasik surgery is one of the most preferred eyes surgeries.
Our eyes are one of the most complicated but important sense of organs. Rays of light enter into our eyes through the cornea, from here light passes through the pupil, hit the lens and focus on the retina. Now an image appears and we could see it. In the normal vision, light directly reaches to the retina. But in a few conditions, the light could not reach to the retina directly. When light could not reach to the retina directly, then it is called a vision problem. This condition is needed to be cured.
What is Lasik Surgery?
Lasik surgery is a popular surgery for eyes which is performed to correct the vision in people with near-sightedness, far-sightedness, and astigmatism and to improve your vision.
