For people who do not like to wear glasses or contact lenses, laser eye surgery seems the obvious choice. Though getting the perfect 20/20 vision is a myth, but not having to fiddle with lenses or glasses seems a fair charm for most. But are laser eye surgeries good or bad? Is everyone happy years after getting LASIK? And what are the pros and cons. For most it is the idea of laser surgery that inspires more than its pros or cons, as it will help relieve from the pain of carrying glasses or lenses.
Let us first understand what is laser
Laser or more popularly known for its one method LASIK, is a laser procedure. It creates a thin flap in the cornea and surgeon folds back this flap and removes some cornea tissues using laser. It is a method used to correct short-sightedness, far-sightedness and astigmatism. All laser surgeries work by reshaping the cornea. LASIK stands for Laser in situ keratomileusis. Simply for a layman, the light travels through the cornea and reflects on retina from where we envision. This light must reach clear and so the cornea is reshaped to improve vision.
