It’s one of the most common post-LASIK panic moments: you’re showering carefully with your eyes shut, and a stream of water hits your face before you can react. Or your child splashes you unexpectedly, or you instinctively wash your face out of habit. Now you’re standing there thinking, “Did I just ruin my surgery?”
Take a breath. A brief, accidental splash of water in your eye after LASIK is rarely a surgical emergency—but it does require the right response. The corneal flap created during Femto LASIK (or the small incision in SMILE Pro) needs time to heal, and water from taps, showers, and pools can carry microorganisms that a healing eye is vulnerable to. This guide covers exactly what to do in the moment, what warning signs to monitor for, and how to avoid it happening again.
Key Takeaways
- A single accidental splash of tap water usually doesn’t cause lasting damage—but you need to respond correctly and monitor your eye afterwards.
- Never rub your eye after water exposure. Blink gently and use preservative-free artificial tears to flush the eye.
- Contact your surgeon’s office the same day to report the incident, even if you feel fine.
- Avoid all water contact with your eyes for at least 7–14 days after LASIK; swimming pools and hot tubs should wait 4 weeks.
Why Water Is a Risk After LASIK
During LASIK, a thin corneal flap is created and repositioned after the excimer laser reshapes the underlying tissue. In the first days and weeks, that flap is reattaching through a biological adhesion process—not stitches. Until this process completes, the interface between the flap and the stromal bed is vulnerable to contaminants.
Tap water, despite being treated, isn’t sterile. It can harbour bacteria like Acanthamoeba, Pseudomonas, and other microorganisms that don’t pose a problem for intact eyes but can cause serious infections in a healing post-surgical cornea. The risk is highest in the first week when the epithelium over the flap is still sealing, but some vulnerability persists for several weeks.
Beyond infection, water itself can cause irritation. The chlorine in tap water, the chemicals in pool water, and even the salt in ocean water can trigger inflammation in a cornea that’s already in active healing mode. This is also why your surgeon advises caution about showering after LASIK and gives you specific timelines for water activities.
What to Do Immediately
If water has just entered your eye after LASIK, follow these steps in order.
Don’t Rub Your Eye
This is the most important rule. Your instinct will be to wipe or rub—resist it completely. Rubbing can displace the corneal flap before it has fully adhered, which is a far more serious complication than water exposure itself. If water is dripping from your face, gently pat around the eye area with a clean, lint-free cloth without touching the eyeball or pressing on the lid.
Blink Gently—Don’t Squeeze
Soft, natural blinking helps your tear film wash contaminants away from the corneal surface. Your tears contain lysozyme and other antimicrobial components that provide a first line of defence. Blink normally for 30–60 seconds and let your eye’s natural cleaning mechanism work.
Use Preservative-Free Artificial Tears
If you have your prescribed lubricating drops nearby, instil one or two drops to help flush any remaining contaminants from the tear film. Use only preservative-free formulations—preserved drops can add their own irritants to an already compromised surface.
Apply Your Prescribed Antibiotic Drops
If you’re still within your antibiotic drop regimen (most surgeons prescribe these for the first one to two weeks), apply a dose. These drops are designed specifically to prevent bacterial infection during the vulnerable healing window, and this is exactly the scenario they’re intended for.
Contact Your Surgeon
Call your surgeon’s office or the emergency line the same day—don’t wait for your next scheduled follow-up. In most cases, they’ll ask about the circumstances (what type of water, how much exposure, how many days post-surgery) and either reassure you or ask you to come in for an examination. This isn’t overreacting—it’s responsible post-operative care. Knowing the early signs of infection after LASIK matters, and your surgeon can catch problems before they develop.
Warning Signs to Watch For
In the 48–72 hours following water exposure, be vigilant for symptoms that could indicate an infection or inflammatory response is developing. Contact your eye care provider immediately if you notice any of the following: increasing redness that gets worse rather than better, pain that develops or intensifies after the initial irritation subsides, blurred or hazy vision that wasn’t present before the water exposure, unusual discharge (especially anything yellow, green, or thick), sensitivity to light that seems disproportionate, or a persistent feeling of something gritty or foreign in the eye.
Most patients who get a brief splash of water will experience mild stinging or irritation that resolves within an hour. If symptoms persist beyond that or worsen progressively, that’s the signal to seek urgent evaluation rather than waiting. Early treatment of corneal infections produces dramatically better outcomes than delayed treatment, which is why your surgeon would always prefer you called unnecessarily rather than waited too long.
When Can You Safely Get Water in Your Eyes?
Days 1–3: Maximum Caution
This is the highest-risk window. The epithelium over the corneal flap is still regenerating, and the flap-stromal interface is at its weakest. Avoid any water near the eyes entirely. When washing your face, use a damp cloth below the eyes only—no splashing, no running water over the forehead that could drip down.
Days 3–7: Careful Showering
Most surgeons allow gentle showering from day two or three, but with your eyes firmly closed and the water stream directed away from your face. Keep your back to the showerhead. If you need to wash your hair, tilt your head back so water runs away from the eye area. Some patients find it easier to use a damp cloth for hair washing in the first week.
Week 2–4: Gradual Return to Normal
By the second week, the epithelial seal is significantly stronger. Gentle face washing with clean water becomes acceptable for most patients, though you should still avoid letting water run directly into the eyes. The full timeline for water exposure depends on your individual healing progress and your surgeon’s assessment at follow-up visits.
Week 4 and Beyond: Swimming and Water Sports
Swimming pools, hot tubs, lakes, and the ocean should wait at least four weeks—and many surgeons recommend wearing protective goggles for the first swim even after clearance. Pool chemicals and natural water contaminants pose a higher infection risk than tap water, and submersion creates prolonged exposure rather than a momentary splash.
Which Water Sources Are Most Dangerous?
Not all water carries the same risk. Sterile saline and preservative-free artificial tears pose essentially no threat—they’re designed for the eye. Tap water is a moderate risk due to potential Acanthamoeba and bacterial content, though a brief splash is far less dangerous than prolonged exposure. Pool and hot tub water carry higher risk because chlorine itself irritates healing tissue, and warm standing water can harbour resistant organisms. Natural bodies of water—rivers, lakes, oceans—represent the highest risk category due to uncontrolled microbial content. Even rainwater can carry airborne contaminants that a healing cornea shouldn’t be exposed to.
Interestingly, soap and shampoo exposure is another common accident during recovery. The surfactants in these products are more irritating than plain water, so the same response protocol applies—don’t rub, flush gently with artificial tears, and contact your surgeon.
How to Prevent Water Exposure During Recovery
Prevention is simpler than managing an accident. Wear your protective eye shields during showers for the first week—they create a physical barrier that prevents splashes from reaching the eyes. Face the showerhead with your back so water flows away from your face. Keep showers brief and lukewarm rather than hot, since steam can carry moisture toward your eyes. When washing your face, use a dampened washcloth with your eyes closed rather than cupping water to your face, and always clean the eye area with the method your surgeon recommended rather than improvising.
Conclusion
Getting water in your eye after LASIK is alarming but rarely catastrophic—provided you respond correctly. Don’t rub, flush with preservative-free tears, apply your antibiotic drops, and call your surgeon. The vast majority of patients who experience a brief water splash during recovery heal without any complications. The key is not to let panic lead to eye rubbing (which is more dangerous than the water itself) and not to let embarrassment prevent you from reporting the incident to your doctor.

Frequently Asked Questions (FAQs)
Will a small splash of tap water ruin my LASIK results?
In most cases, no. A brief accidental splash is unlikely to cause lasting damage, especially if you respond correctly by not rubbing and using artificial tears. However, always report the incident to your surgeon so they can monitor for any early signs of infection.
How long after LASIK should I keep water out of my eyes?
Avoid direct water contact for at least 7–14 days. Swimming pools, hot tubs, and natural bodies of water should be avoided for a minimum of four weeks. Your surgeon will give you personalised timelines based on your healing progress.
Can I shower the day after LASIK?
Yes, but carefully. Keep your eyes closed, face away from the water stream, and avoid letting water run directly over your face. Many surgeons recommend wearing protective eye shields during showers for the first week.
What are the signs of infection after water gets in my eye?
Watch for increasing redness, worsening pain, blurred vision, unusual discharge, light sensitivity, or a persistent foreign body sensation. If any of these develop within 48–72 hours of water exposure, contact your surgeon immediately.
Should I use my antibiotic drops after getting water in my eye?
Yes. If you’re still within your prescribed antibiotic drop schedule, apply a dose after flushing the eye with preservative-free artificial tears. These drops are specifically designed to prevent infection during the healing window.
