You’re one week out from LASIK, your vision is already clearer than it’s been in years — and then you feel it: an ache, a sting, or a dull pressure behind the eye that wasn’t there yesterday. It’s unsettling. But before you spiral into worst-case scenarios, you should know that some degree of discomfort at the one-week mark is common, well-understood, and almost always temporary.
That said, not all post-LASIK eye pain is the same. A mild gritty sensation from dry eye is completely different from sharp, worsening pain with redness and light sensitivity — and the two require very different responses. This guide explains the five most common causes of eye pain one week after LASIK, gives you a clear framework for distinguishing normal healing discomfort from warning signs, and tells you exactly when to contact your surgeon. Whether you had Femto LASIK, Contoura Vision, or SMILE Pro, the principles below apply.
Key Takeaways
- Mild aching, grittiness, or stinging at one week post-LASIK is usually caused by dry eye or corneal nerve regeneration — both are normal parts of healing.
- Pain that is sharp, worsening, or accompanied by redness, discharge, light sensitivity, or vision changes is not normal and requires same-day evaluation.
- Preservative-free artificial tears, adequate rest, and strict adherence to your eye drop regimen are the most effective ways to manage week-one discomfort.
- Most routine post-LASIK discomfort resolves within two to four weeks as the corneal surface stabilises and tear film recovers.
Why Does Your Eye Hurt One Week After LASIK?
Dry Eye — The Most Common Culprit
Dry eye accounts for the majority of discomfort reported at the one-week mark. During LASIK, the corneal flap creation severs the sub-basal nerve plexus — the network of sensory nerves that triggers your blink reflex and stimulates tear production. With those nerves temporarily offline, your eyes produce fewer tears and the tears they do produce may evaporate faster. The result is a stinging, burning, or gritty sensation that worsens in dry environments, during screen use, or first thing in the morning. This is expected, temporary, and manageable with preservative-free lubricating drops. For most patients, tear function recovers substantially within three to six months as nerves regenerate.
Corneal Nerve Regeneration
At one week, the severed corneal nerves are beginning to regrow — and nerve regeneration can produce sensations that range from mild tingling to intermittent sharp twinges. This is similar to the “pins and needles” feeling you get when a numb limb wakes up. These transient episodes of discomfort are a sign that healing is progressing normally. They come and go unpredictably, are rarely severe, and typically resolve within the first month. For a deeper look at this process, see our page on corneal nerve regeneration after LASIK.
Residual Inflammation
LASIK involves tissue manipulation, and the body’s natural inflammatory response doesn’t switch off instantly. At day seven, trace levels of inflammation may still be present in the corneal interface — which is exactly why your surgeon prescribes a tapering course of anti-inflammatory steroid drops (typically prednisolone or fluorometholone) for the first one to two weeks. If you’ve been inconsistent with your steroid eye drops, residual inflammation may be the cause of your discomfort. Don’t stop or skip your prescribed drops without consulting your surgeon.
Light Sensitivity (Photophobia)
Increased sensitivity to bright light is common in the first week after LASIK and can feel like a dull ache or pressure when you step into sunlight or face bright screens. This happens because the healing corneal surface and dilated pupils let more light through than your retina is accustomed to. Wearing quality UV-protective sunglasses outdoors and reducing screen brightness indoors are the simplest remedies. Photophobia after LASIK almost always resolves within two to three weeks.
Flap-Related Issues (Rare but Serious)
In a small number of cases, eye pain at one week may indicate a flap complication — such as a micro-wrinkle (striae), epithelial ingrowth under the flap edge, or early-stage diffuse lamellar keratitis (DLK, sometimes called “sands of the Sahara” syndrome). These are uncommon — affecting fewer than 1–2% of patients — but they require prompt clinical evaluation. The distinguishing feature is that flap-related pain is typically accompanied by other symptoms: worsening vision, visible redness, increasing light sensitivity, or the sense that something is progressively getting worse rather than gradually improving. If your pain matches this pattern, contact your surgeon the same day. Learn more about flap healing at LASIK flap healing stages.
What’s Normal and What’s Not
Normal at One Week
Mild grittiness or dryness, especially in air-conditioned rooms or after prolonged screen use. Occasional stinging that resolves within seconds after blinking or applying drops. Intermittent sharp twinges that come and go (nerve regeneration). Mild aching behind the eyes at the end of a long day. Sensitivity to bright light that improves with sunglasses. A general sense that your eyes feel “tired” even when vision is clear.
Not Normal at One Week
Pain that is steadily worsening rather than gradually improving. Sharp, constant pain that doesn’t respond to lubricating drops or rest. Significant redness that wasn’t present at your day-one or day-three follow-up. New onset of blurred or hazy vision after initially clear vision. Thick or coloured discharge from the eye. Extreme light sensitivity that prevents you from opening your eyes indoors. If you experience any of the above, do not wait for your next scheduled follow-up — contact your eye care provider the same day.

How Long Does Post-LASIK Pain Typically Last?
The immediate post-operative discomfort — the stinging, watering, and foreign-body sensation from the first few hours — peaks within four to six hours of surgery and largely resolves by the next morning. What remains during the first week is usually low-grade: background dryness, occasional twinges, and light sensitivity. For most patients, this residual discomfort diminishes steadily through weeks two and three and is negligible by one month.
Dry eye specifically can take longer to fully resolve — three to six months for complete nerve-mediated tear recovery — but it transitions from “discomfort” to “occasional awareness” well before that. If your discomfort at one week is noticeably better than at day three, you’re on a normal trajectory even if you’re not yet pain-free. If pain at one week is the same as or worse than day three, that plateau warrants a call to your surgeon.

What Helps: Managing Pain at Home
Stay on Top of Your Drop Regimen
This is the single most important thing you can do. Your prescribed antibiotic drops prevent infection. Your steroid drops control inflammation. Your preservative-free artificial tears maintain the tear film that protects the healing surface. Skipping doses — particularly the steroid drops — is one of the most common reasons discomfort persists or worsens in the first week. Set alarms if you need to.
Lubricate Aggressively
In the first two weeks, more drops are better than fewer. Apply preservative-free artificial tears every one to two hours while awake, even when your eyes feel fine. The goal is to prevent the dryness cycle from starting — not to treat it after it’s already causing pain. If standard drops aren’t providing enough relief, ask your surgeon about thicker gel drops for nighttime use. For product guidance, see best eye drops for dry eyes after LASIK.
Protect Your Eyes from Drying Triggers
Direct AC or fan airflow on your face, prolonged screen time without breaks, and dusty or smoky environments all accelerate tear evaporation and worsen discomfort. Use the 20-20-20 rule for screens (every 20 minutes, look at something 20 feet away for 20 seconds), angle vents away from your face, and wear your protective goggles or wraparound glasses when outdoors or in windy conditions.
Rest Your Eyes
Your corneas heal faster when your eyelids are closed. Adequate sleep in the first week is therapeutic — not a luxury. If you’re able, take short rest breaks during the day where you close your eyes for 10–15 minutes. This alone can meaningfully reduce end-of-day discomfort. Avoid rubbing your eyes even if they itch — this is when accidental flap displacement is most likely.
When to Call Your Surgeon Immediately
Post-LASIK eye pain warrants an urgent same-day call if you experience any of the following: pain that is escalating rather than stable or improving, sudden onset of blurred vision in an eye that was previously seeing clearly, significant new redness (not the mild pink that was present at day one), thick white or yellow discharge, pain so severe that over-the-counter analgesics provide no relief, or extreme photophobia that prevents you from functioning indoors. These symptoms may indicate infection, inflammation (DLK), epithelial ingrowth, or elevated intraocular pressure from steroid response — all of which are treatable but require prompt intervention to protect your visual outcome. Don’t self-diagnose — let your surgeon examine you.
Conclusion
Eye pain one week after LASIK is common, usually mild, and almost always related to dry eye, corneal nerve regeneration, or residual inflammation — all of which are normal parts of the healing process and resolve within weeks. The key is distinguishing routine discomfort (stable or improving, responds to drops, no accompanying visual changes) from warning signs (worsening pain, new redness, vision changes, discharge). Stay consistent with your prescribed eye drops, lubricate aggressively with preservative-free tears, protect your eyes from drying triggers, rest adequately, and never hesitate to contact your surgeon if anything feels like it’s getting worse instead of better. A few weeks of careful attention now protects a lifetime of clear vision.

Frequently Asked Questions (FAQs)
Is it normal for my eyes to still hurt a week after LASIK?
Mild discomfort — grittiness, dryness, occasional stinging — is common and normal at one week. It usually reflects dry eye and nerve regeneration. Worsening or sharp constant pain is not normal and should be evaluated promptly.
What is the most common cause of eye pain after LASIK?
Dry eye is the most frequent cause. LASIK temporarily disrupts the corneal nerves that stimulate tear production, leading to dryness, stinging, and burning that peaks in the first one to two weeks.
How do I know if my eye pain after LASIK is serious?
Pain is concerning if it is getting worse rather than better, is accompanied by redness, discharge, blurred vision, or severe light sensitivity, or doesn’t respond to lubricating drops and rest. Contact your surgeon for same-day evaluation.
Can I take painkillers for eye pain after LASIK?
Paracetamol (acetaminophen) is generally safe and commonly recommended. Avoid ibuprofen or aspirin in the first week unless your surgeon specifically approves them, as they can affect clotting and potentially increase the risk of subconjunctival haemorrhage.
Will the pain go away on its own?
In most cases, yes. Routine post-LASIK discomfort from dry eye and nerve healing typically resolves within two to four weeks. Persistent or worsening pain beyond this timeframe should be evaluated by your surgeon.
Does SMILE Pro cause less pain than LASIK?
Generally, yes. SMILE Pro’s flapless design severs fewer corneal nerves, which means less post-operative dry eye and less discomfort in the first week compared to flap-based LASIK procedures.
