Quick Answer
Yes. PRK involves more discomfort than LASIK during the first 3–5 days post-surgery. Because the corneal epithelium is fully removed — rather than preserved under a flap — the eye’s nerve endings are exposed during healing. Patients typically describe a burning, gritty, or foreign-body sensation peaking on days 2–3. Discomfort largely resolves by day 5–7 when the epithelium regenerates. The procedure itself is painless for both PRK and LASIK.
Detailed Explanation
Pain is one of the most frequently asked questions about PRK — and one of the most honest reasons patients hesitate. The discomfort is real. Understanding the mechanism, the timeline, and the management strategies will help you prepare effectively.
During the Procedure: Both Are Painless
Neither PRK nor LASIK hurts during the surgical procedure itself. Topical anesthetic drops are applied before surgery, completely numbing the corneal surface. Most patients feel pressure, a sensation of movement, and smell a faint odor from the laser ablation — but not pain. The procedure lasts 5–10 minutes per eye.
The First 24 Hours: Mild to Moderate
As the anesthetic wears off — typically 1–2 hours after surgery — PRK patients begin to notice discomfort. In LASIK patients, the flap provides immediate protection, and discomfort is typically mild and resolves within hours. PRK patients experience the opposite trajectory: discomfort increases over the first day as the exposed epithelial bed becomes more inflamed.
Days 2–3: Peak Discomfort
This is the hardest phase of PRK recovery. Patients commonly describe:
- A persistent gritty or scratchy sensation (like sand in the eye)
- Burning or aching that worsens with light exposure
- Significant photophobia (light sensitivity) requiring dimmed rooms and sunglasses indoors
- Tearing and reflex tearing
- Difficulty keeping the eye open
Scores on pain scales reported in patient surveys typically range from 3–6 out of 10 during this window, with some patients reporting higher peaks. The discomfort is manageable but genuinely unpleasant.
Days 4–5: Transition Point
Epithelial regeneration is largely complete by day 4–5 in most patients. The bandage contact lens placed by the surgeon at the end of the procedure is removed at a follow-up appointment during this window. Removal of the bandage lens marks the end of peak discomfort for most patients. Many describe the day of lens removal as a turning point — significant relief within hours.
Days 5–14: Residual Sensitivity
After lens removal, most patients describe a residual sensitivity to light and occasional mild discomfort rather than true pain. Dry-eye-type symptoms (fluctuating vision, mild irritation) persist but are significantly less intense. Most patients can function without oral pain medication by day 5.
Pain Management Strategies Surgeons Use
- Bandage contact lens: Acts as a physical barrier over the exposed corneal surface throughout the healing phase.
- Topical NSAIDs (ketorolac, diclofenac): Applied 2–4 times daily in the first 2–3 days. These are the most effective tools for reducing acute PRK discomfort.
- Cold compresses: Reduce inflammation and provide localized relief.
- Oral analgesics (ibuprofen, acetaminophen): Standard OTC options are sufficient for most patients.
- Refrigerated artificial tears: Cooling effect provides additional comfort between NSAID applications.
- Oral sedatives/sleep aids: Some surgeons prescribe these for the first 2 nights to help patients sleep through peak discomfort.
Note: Topical NSAIDs are effective but should not be used beyond the surgeon-prescribed duration. Overuse can paradoxically slow epithelial healing.
How to Compare With LASIK Honestly
LASIK discomfort is real but minor. Most LASIK patients experience a burning or tearing sensation for 2–4 hours post-surgery, then mild dryness and occasional light sensitivity for 1–2 weeks. PRK is categorically more uncomfortable during that first week. By week 2, the experiences converge. By month 2, there is no meaningful difference in patient-reported comfort between PRK and LASIK outcomes.

Important Considerations
Prepare your home environment before surgery. You will not want to run errands on day 2. Stock artificial tears, pain medication, cold packs, sunglasses, and easy-to-prepare food before your procedure date.
Do not use topical NSAIDs beyond the prescribed schedule. It is tempting to use ketorolac drops more frequently when discomfort peaks. Overuse delays epithelial healing and can cause secondary complications, including corneal melting in rare cases.
Some patients experience significantly more discomfort than average. Patients with very high prescriptions (more tissue removal), pre-existing dry eye, or slow epithelial healing have more prolonged discomfort. Discuss your specific risk profile with your surgeon.
Sleep is the best management tool. The most uniformly effective patient-reported strategy for the peak discomfort phase is sleeping as much as possible through days 1–3. Sleep minimizes light exposure, reduces eye movement, and speeds subjective recovery.
PRK discomfort does not predict your final outcome. A difficult recovery does not mean the procedure failed. Vision and comfort outcomes at 3 months are independent of the intensity of recovery discomfort.
What to Do Next
1. Plan 4–5 days of home rest. Budget for at least day-of-surgery plus four full recovery days at home with minimal screen time and bright light exposure.
2. Fill all prescriptions before surgery day. You will not want to visit a pharmacy after the procedure.
3. Ask your surgeon about topical NSAID protocol. Not all PRK surgeons use the same drop schedule. Understanding yours in advance prevents confusion when discomfort peaks.
4. Understand the full recovery arc. How Long Does PRK Recovery Take gives the complete week-by-week timeline beyond the discomfort phase.
