Dry Eye After LASIK

LASIK is an increasingly common and popular procedure for correcting refractive errors. However, it has also been known to commonly lead to dry eye following the procedure. Below we explore this issue, and what to do about it.

Symptoms of Dry Eye

Dry eye has several common symptoms. If you are experiencing them, especially for an extended period of time, it is likely that you are experiencing dry eye. Apart from the obvious feeling of dryness in the eyes, symptoms can include:

• Excessive tear production
• Mucus collection around the eyes
• A sensation of burning or stinging in the eyes.
• Blurry vision
• Eye fatigue

Why Does LASIK Cause Dry Eye?

There is still debate on the exact reason why dry eye is so common following a LASIK procedure. However, there are a couple of theories.

One is that due to the nature of the procedure, which involves the reshaping of the cornea by removing some tissue from beneath it, some nerves in the area are cut. This has no impact on vision, but it can temporarily impact the communication between the cornea and the tear glands, leading to drye eye, though it is generally short-lived.

Another possibility is that post- LASIK dry eye is due to inflammation from the surgery. Additionally, the newly reshaped cornea may alter the way that the eyelid interacts with the surface of the eye. Both of these issues can lead to dry eye.

How Long Does Post-LASIK Dry Eye Last?

In the vast majority of cases, dry eye which manifests shortly after LASIK will get better within 6-12 months.

When Should I See a Doctor if I Experience Dry Eye After LASIK?

Even if you are only experiencing mild dry eye symptoms, it is a good idea to speak with a doctor, though if they are mild, you do not necessarily have to see them immediately, as standard dry eye treatments such as eye drops can be effective. However, if you experience severe discomfort, or the symptoms get worse, see a doctor immediately.

Can I Avoid Dry Eye After LASIK?

It is difficult to completely avoid dry eye post LASIK. However, if you closely follow the postoperative instructions given to you by your eye surgeon, you will have a better chance of minimizing symptoms, if not avoiding them completely.

How Can I Treat Post-LASIK Dry Eye?

As mentioned previously, for mild cases of dry eye, basic treatments like eye drops or artificial tears can suffice. In more severe cases, you should see your doctor for advice. Even for mild cases, it is recommended to at least speak to your doctor to get recommendations as opposed to self-treating, so you can minimize the chances of making things worse.
