LASIK, or Laser-Assisted In Situ Keratomileusis, is a surgical procedure that is done on the eye to correct vision. Most people who have LASIK done do not need to wear contact lenses or eyeglasses anymore. It is important to carefully consider whether LASIK is right for you.
Function
LASIK works by changing the shape of the cornea, which is the part of the eye that focuses light to create an image. Fixing the shape of the cornea improves the way the patient sees images and objects.
Types
The two types of LASIK are "blade" and "bladeless." In the traditional procedure, a tiny instrument called a microkeratome cuts a flap in the cornea. In the laser, or bladeless, procedure, the vision correction is done with a laser instead of a blade.
Benefits
Some benefits that LASIK has over contact lenses include higher levels of comfort and the convenience of not having to care for lenses.
Risks
Some of the risks of having LASIK include eye infections, eye dryness, poor night vision and distorted vision. These may be temporary or permanent.
Considerations
Considerations to keep in mind when deciding if LASIK is right for you include the cost and your current health status. Pregnant women cannot have LASIK.
