FAQ

Q

What is LASIK?

A

The cornea is a part of the eye that helps focus light to create an image on the retina. It works in much the same way that the lens of a camera focuses light to create an image on film. The bending and focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is out-of-focus. These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: myopia, hyperopia and astigmatism. Persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects.  Persons with hyperopia, or farsightedness,  have more difficulty seeing near objects as clearly as distant objects.  Astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye. Combinations of myopia and astigmatism or hyperopia and astigmatism are common. Glasses or contact lenses are designed to compensate for the eye's imperfections. Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery. In LASIK surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power.

Q

Will I still need glasses after my LASIK procedure?

A

For most patients, LASIK eye surgery will correct refractive errors so much, that they no longer require the use of their eyeglasses or contacts. However, the need for reading glasses occurs naturally in most people in their early 40's whether they are nearsighted, farsighted or normal. Laser vision correction can be calibrated to avoid reading glasses after 40 if one eye is kept slightly nearsighted - this is called monovision LASIK

Q

Is LASIK painful?

A

Throughout the entire procedure, your eyes will be numbed so that you will not feel any discomfort or pain For approximately 1-3 hours after the surgery, you may experience mild tearing or a foreign body sensation, like an eyelash in your eye.  This sensation disappears after sleeping and, if needed, a topical eye drop is supplied for use after surgery. Usually, any discomfort goes away after a few hours

Q

Is the procedure done under anesthesia?

A

Yes.  Prior to surgery, the eye is anesthetized with eye drops.  The anesthetic used is the same powerful eye drops used during cataract surgery, which is far more invasive than LASIK. As a result, it is considered a painless procedure.

Q

Is LASIK permanent?

A

Yes, the laser permanently etches the correct shape to your cornea
