LASIK reshapes the cornea so light focuses more clearly, and many people see well without glasses or contacts afterward. Recovery comes with a few side effects, though, and dryness is the one people ask us about most.
Yes, LASIK can cause dry eye, and for most people the symptoms ease within 3 to 6 months as the eye heals. If you’re still deciding on surgery, bring up dryness at your laser eye surgery consultation so you know your risk going in. And if your eyes already feel dry after LASIK, dry eye treatment can help you stay comfortable while you heal.
Why LASIK Can Cause Dry Eye
During LASIK, your surgeon creates a thin flap in the cornea and uses a laser to reshape the tissue underneath. Making that flap cuts some of the corneal nerves that tell your eyes to blink and make tears. When those nerves can’t send as many signals, your eyes may produce fewer tears and blink less often.
Post-surgery inflammation can worsen dryness. The cornea’s new shape may also change how your eyelid moves across the surface of your eye.
Signs of Dry Eye After LASIK
Dry eye after LASIK can feel different from person to person. Watch for any of these symptoms:
- A gritty feeling, like there’s something in your eye
- Burning
- Itching
- Redness
- Sensitivity to light
Watery eyes can happen too, which sounds backward. When the surface of your eye gets irritated, it may respond with a rush of tears that drain away before they can do much good.
How Long Dry Eye Lasts After LASIK
Dry eye is the most common LASIK side effect, and symptoms usually ease within 3 to 6 months. The most common sign is blurry vision that clears again, especially in the first 6 weeks.
For a smaller group of people, dryness lasts longer. Many notice it most at the end of the day or in dry, windy weather. Jot down how your eyes feel each week so you and your optometrist can tell whether things are improving.
Who Faces Higher Risk for Dry Eye
Some people have a higher chance of noticing dryness after surgery, including those who:
- Had dry eye before LASIK
- Are going through perimenopause
- Have an autoimmune condition, including thyroid disease
- Are older adults
- Take medications that can dry out your eyes, like antihistamines or antidepressants
Contact lens discomfort is a common reason people look into LASIK in the first place. Sometimes that discomfort is dry eye that hasn’t been diagnosed yet.
Mention any of these to your optometrist before your procedure. Treating dry eye ahead of time can make your recovery more comfortable.
Ways to Manage Dry Eye After LASIK
A few simple habits can help your eyes feel better while they heal:
- Use the lubricating drops your surgeon recommends
- Run a humidifier at home, especially overnight
- Rest a warm, damp washcloth over your closed eyes for a few minutes, once your surgeon says it’s okay
- Follow the 20-20-20 rule on screens: every 20 minutes, look at something 20 feet away for 20 seconds
- Wear sunglasses outdoors to keep wind off your eyes
Screen time matters more than most people expect. We tend to blink less while reading or scrolling, so give your eyes regular breaks, even on busy workdays.
Dry Eye Treatments Your Optometrist May Recommend
When home care isn’t enough, your optometrist can examine your tear film and eyelids to see what’s behind the dryness. Depending on what they find, options may include:
- Prescription eye drops that can help your eyes make more of their own tears
- Punctal plugs, tiny inserts that slow tear drainage so moisture stays on your eye longer
- OptiLight by Lumenis, a light-based treatment for dry eye related to the oil glands in your eyelids
These treatments can work alongside artificial tears. You may not have to give up the drops you’re already using, though your optometrist might adjust how often you use them.
When to See Your Optometrist About Dry Eye
Some dryness after LASIK is expected. Book an eye exam if you notice:
- Symptoms that last longer than 6 months
- Dryness that makes it hard to drive or read
- Eye pain that keeps getting worse
- Blurry vision that doesn’t clear when you blink or use drops
Bring a list of any medications and supplements you take. Some may affect how dry your eyes feel.
