Dry Eye and LASIK

Posted by Dr. Danny P. Malone on May 25, 2016 8:30:00 AM

Dry eye syndrome is the most common side effect of LASIK, with as high as 95% of patients reporting dry eyes after surgery. But it is important to keep in mind that as high as 75% of patients have dry eye before surgery

Given this, it’s critical to carefully evaluate the causes of dry eye before any LASIK surgery in order to avoid or ameliorate post-surgery problems. In fact, it is best to address those causes before you undergo any type of refractive surgery. 

What Causes Dry Eye After LASIK?

So you can expect some dry eye immediately after LASIK which can continue for weeks or months after as those nerves grow back. This is true especially during the first 6 weeks after surgery.

LASIK vs PRK

Surgeons have two major choices for refractive surgery: LASIK and PRK. 

In a review of research studies, the Ophthalmology Times article “Dry eye: PRK or LASIK?” found that both types of surgery were effective in correcting vision. They further found that while nerve density recovery may be faster with PRK, it will return to normal over time with both. Even so, they suggested that surgeons consider PRK over LASIK for those with pre-existing dry eye syndrome.

It’s a tough choice, but the key is to first treat your existing condition and only then undergo surgery. This will ensure that your postoperative recovery will be smoother with few surprises.
