Am I a Candidate for LASIK?

More than 20 million Americans have had LASIK surgery since the FDA approved it more than 20 years ago. If you have to wear glasses or contact lenses, you may have thought about having this life-changing surgery. 

The technology has improved since the procedure was introduced, so even if your eyes weren’t suited for LASIK in 1999, you might be now.

Our expert optometrists and ophthalmologists provide comprehensive exams at Paragon Eye Associates in Arlington and Mansfield, Texas, to determine if you’re a good candidate for LASIK. We also have a state-of-the-art WaveLight® Refractive Suite technology to perform LASIK on our patients.

So, who is a good candidate for LASIK, and what, if any, conditions preclude you from the procedure?

LASIK eligibility criteria

These days, LASIK can correct a wide range of refractive errors, including:

You need to be 18 or older and have a stable eyeglasses prescription that hasn’t changed in two years. You should also be in good health overall. 

What would prevent me from having LASIK?

A few conditions would make you ineligible for LASIK.


If you have glaucoma or ocular hypertension, you shouldn’t have LASIK. The suction device we use to lift your cornea flap significantly but temporarily increases your intraocular pressure. This can increase the risk of damaging your retina and optic nerve. 

Eye inflammation 

Eye diseases such as keratitis, uveitis, herpes, and blepharitis that cause inflammation in your eyes and eyelids can also be exacerbated by LASIK. The treatment can also trigger dry eye, and you might not be eligible if you have chronic dry eye symptoms.

Thin corneas

During LASIK, we make an incision in your cornea, and it needs to be thick enough to withstand the laser. If your corneas are too thin, we won’t be able to perform the operation. 

Large pupils

If you have large pupils, we need to make a larger incision in your cornea. However, the larger the incision, the higher your risk of developing complications that lead to debilitating vision aberrations such as starbursts, halos, and multiple images. 


Keratoconus is a condition that causes abnormalities in your cornea. Your cornea bulges, which makes it more difficult and potentially dangerous to perform LASIK.

Certain health issues

In addition to eye health problems, other health issues that interfere with the way your body heals can make you ineligible for LASIK. For example, diabetes, HIV/AIDS, and autoimmune conditions like lupus and rheumatoid arthritis could interfere with the success of the procedure.

If you’re interested in LASIK, call our offices in Arlington and Mansfield, Texas, or send a message to our team online today to schedule a consultation. 

Even if you have a condition that might stop you from having LASIK, we consider each patient’s needs individually, and we may recommend other treatment options.
