Pomona LASIK Side EffectsFor our patients in Pomona, LASIK has delivered life-changing results. This revolutionary treatment has helped people who have always relied upon glasses and contact lenses for everyday activities to significantly reduce this dependency - or, in some cases, to eliminate the need for corrective eye wear altogether. LASIK surgery is considered safe and effective when performed by a credentialed professional. However, as with any surgical procedure, it is imperative to understand that there are side effects associated with the LASIK procedure.

Dry Eye after LASIK

Following surgery at our Pomona laser vision center, you can expect to feel some irritation, and to experience dry eyes. You may receive special eye drops that will help to relieve irritation and maintain proper lubrication in the eyes. In some cases, the dryness may persist, and the tear ducts may continue failing to produce adequate tears to lubricate the eye. When it comes to LASIK side effects, dry eye is the most common. It can be treated in a number of ways. The simplest is to purchase over-the-counter eye drops. These are specially formulated, and different from the common eye drops used for relieving redness and itchiness. If these fail, there are prescription eye drops, as well as special capsules placed behind the eyelid that slowly dissolve, providing the necessary lubrication.

Light and Contrast Sensitivity

Other LASIK side effects you may temporarily experience immediately following surgery include a sensitivity to light. It is important to resist rubbing your eyes when this happens, as it can disrupt the healing process. You may also experience a loss of contrast sensitivity in the first six months following treatment. This can make it difficult to discern some objects, particularly in low light. During the healing process, a lack of some visual clarity is common, but will eventually subside.


Halos, or blurry rings surrounding lights at nighttime are another potential side effect of LASIK. LASIK requires the creation of a “flap” in the top layer of the corneal tissue, granting access to the layers below. In the majority of cases, this side effect goes away within a couple of weeks of surgery. Some patients may have a pupil that dilates larger than the flap, and this can cause halos to appear around light sources at night in the long term. Your doctor should gauge the size of your pupils prior to surgery to determine if you are at risk for developing any long term side effects.

Flap Complications

The flap itself is subject to potential complications following surgery, though it should be noted that this occurs in less than one percent of all LASIK surgeries. In rare instances, the flap can become detached from the cornea. To minimize this risk, doctors usually recommend patients go home and rest immediately, which allows the flap to begin healing. In other unusual instances, the flap can become infected.
