Refractive surgeons are beginning to better understand the importance of evaluating the ocular surface of LASIK patients for the presence of active ocular allergy prior to surgery.

Uncontrolled allergy is a contraindication for LASIK.

Ocular allergy is now appreciated as a significant elevated risk factor for complications following LASIK and other refractive procedures. In one study, untreated allergic conjunctivitis was identified as a significant risk factor for late-onset corneal haze and myopic regression following PRK.

In another study, atopic patients who underwent bilateral myopic astigmatic primary LASIK were five times more likely to exhibit lamellar keratitis (DLK) than those with no atopy.

Ocular allergies may lead to a range of LASIK problems including displaced flaps from rubbing, epithelial ingrowth and striae, which, in the long term, can cause fibrosis of the lid margin.

The presence of an active ocular allergy (elevated IgE) represents an increased risk factor for all forms of ocular surgery, including LASIK, and can now be easily detected and managed through the use of ATD’s IgE test.

Clinical study on this topic continues to be expanded.
