The process by which Lasik eye surgery runs is relatively simple, fast and causes the least possible pain over the process. The immense success graph as well as dropping price level turns the lasik operation the viable solution for rectification of sight.
Then also one should not take this procedure to be fully advanced. The answer behind this is each and every eye is formed differently and the amount of tilt on the cornea influence the length of vision matters.
The eye specialist must mark how much cornea should have to be removed/ repaired to rectify the patient's vision to 20/20. Since there is no method to know how the cornea will reciprocate to the beam and how near the patient is to correct sight causing this rather difficult. But, we directed at increased vision and not right vision. Mostly people actually, are able to have 20/20 visual perception after experiencing Lazer Eye Therapy.
