What is Refractive Surgery?

For people who are nearsighted, certain refractive surgery techniques will reduce the curvature of a cornea that is too steep so that the eye's focusing power is lessened. Images that are focused in front of the retina, due to a longer eye or steep corneal curve, are pushed closer to or directly onto the retina following surgery.

Refractive surgery might be a good option if you:

Want to decrease your dependence on glasses or contact lenses
Are free of eye disease
Accept the inherent risks and potential side effects of the procedure
Understand that you could still need glasses or contacts after the procedure to achieve your best vision
Have an appropriate refractive error

Various types of refractive surgeries?

The refractive power of the eye can be changed by any of the three approaches:
Changing The Curvature Of The Cornea: This is the most popular mode of refractive surgery.
Removing The Natural Lens And Replacing It With An Artificial Lens Of Adequate Power: It is similar to a routine phacoemulsification surgery, except that it is done in a clear lens and not a lens with cataract.
Putting An Additional Artificial Lens Within The Eye On Top Of The Existing Natural Lens: This Procedure is called Phakic IOL implantation
