Why would someone get LASIK eye surgery procedure?

LASIK can be used to correct nearsightedness (myopia,) farsightedness (hyperopia) and astigmatism. Myopia and hyperopia are refractive errors that are caused by variations in the shape of the eyeball. Astigmatism is a result of an irregular-shaped cornea, which is the transparent outer portion of the eye surface.

What is the LASIK eye surgery procedure?

Surgeons can use the two-step LASIK procedure in different ways, specialized for each patient, to correct refractive errors. Generally, the process involves reshaping the cornea to improve the way that light rays focus on the retina (the light-sensitive, back portion of the eye.)

First, surgeons use either a bladed instrument called a microkeratome or a laser to create a precise flap of the cornea. This hinged flap, which is still attached to the cornea, is raised.

Next, surgeons will use an excimer laser to reshape the cornea by accurately removing corneal tissue. The preoperative eye exam determines how much tissue should be removed for each patient.

An advanced technology, custom wavefront LASIK, is available that allows surgeons to further refine the standard LASIK procedure and enable more precise vision corrections.      

Is the LASIK eye surgery procedure painful?

LASIK, which is an outpatient surgical procedure, takes place under local anesthetic. The surgery itself is considered painless and takes only a matter of minutes per eye. After surgery, the natural healing processes of the eye take over to help seal the flap of the cornea.

What risks are involved with LASIK?

Although LASIK eye surgery is considered safe, there are risks involved. These include poor night vision due to halos, bright light sensitivity, dry eyes, double vision and regression. More rarely, serious complications such as infection or weakening of the cornea could occur.
