Risks of Lasik

A small percentage of people may need to have another surgery because the condition is over- or under-corrected. Sometimes, you will still need to wear contact lenses or glasses.
LASIK is eye surgery that permanently changes the shape of the cornea (the clear covering on the front of the eye) in order to improve vision and reduce a person's dependency on glasses or contact lenses.

Risks may include:

* Corneal infection
* Corneal scarring or permanent problems with the cornea's shape, making it impossible to wear contact lenses
* Decrease in contrast sensitivity -- even with 20/20 vision, objects may appear fuzzy or gray
* Dry eyes
* Glare or haloes
* Light sensitivity
* Night driving problems
* Patches of red or pink in the white of the eye (usually temporary)
* Reduced vision or permanent vision loss
* Scratchiness
