The First Hours After Surgery: Gentle Care Matters Most

After SMILE or LASIK, your eyes will begin healing immediately — but they’re also highly sensitive.

You may notice:

Mild tearing or watery eyes
A sandy or foreign-body sensation
Slight light sensitivity or hazy vision

These are normal signs that your cornea is healing.

What to do:
Keep your eyes closed and rest. The first 2–3 hours after surgery are for recovery. Light sleep helps your eyes begin sealing the microscopic incision made during SMILE.
Do not rub your eyes. Even gentle rubbing can disturb healing tissue. If they itch or water, blot your cheeks instead of touching your eyelids.
Use your prescribed eye drops exactly as directed. At SNU Eye Clinic, every patient leaves with a custom drop schedule including:

Antibiotic drops (to prevent infection)
Anti-inflammatory drops (to control healing response)
Artificial tears (to relieve dryness)

Dr. Chung Eui Sang, our lead surgeon, emphasizes:

“Even the best technology can’t replace disciplined aftercare. Drops are your invisible shield — they keep your new cornea healthy.”

The First Day: Let Your Vision Settle Naturally

Your vision may fluctuate during the first 24 hours — some moments are crystal clear, others slightly hazy.

This is normal. The cornea is adjusting its hydration and optical balance.

Tips for Day 1:

Avoid screens and reading. Bright light or focusing too long can strain healing tissue.
Wear protective goggles (provided by our clinic) when sleeping to avoid accidental touching.
Keep your environment clean. Avoid dusty or smoky areas — your eyes are more vulnerable to irritation.
Eat and hydrate well. Omega-3–rich foods (like salmon or flaxseed) and adequate water support tear film recovery.

At SNU Eye Clinic, most SMILE patients notice functional vision within 4–6 hours — enough to navigate comfortably by evening.

The First Week: Protect, Hydrate, and Heal

During the first week, your cornea strengthens and your vision stabilizes. The risk of infection or inflammation is small — but still possible if care instructions aren’t followed closely.

What to Do:

Use all prescribed drops. Do not skip doses. Bring them to your follow-up visits for adjustment if needed.
Avoid makeup and facial creams around your eyes. Tiny particles or bacteria can enter through healing microchannels.
Wear sunglasses outdoors. UV exposure can trigger temporary haze or dryness; good UV protection supports smoother healing.
Stay away from water. No swimming, saunas, or direct shower spray near your eyes. When washing your face, use a damp cloth instead.
Blink consciously and often. This helps spread natural tears evenly across your cornea.

What to Expect:

Mild dryness or fluctuating sharpness
Slight sensitivity to bright lights
Gradually increasing clarity

If your eyes feel tired, close them and rest — healing accelerates when your body relaxes.

Weeks 2–4: Returning to Normal Life — Safely

By now, most patients at SNU Eye Clinic can resume nearly all normal activities.

You can:

Use computers, phones, and read comfortably
Return to work
Drive (once cleared by your doctor)
Exercise gently (yoga, walking, cycling)

Still avoid:

Swimming or diving (for at least 3–4 weeks)
Contact sports like basketball or martial arts
Excessive eye rubbing or direct wind exposure

Monitor Your Dryness Levels

It’s common to experience temporary dryness, especially after LASIK or SMILE.
Artificial tears (preservative-free) are safe to use up to 6–8 times daily.

“Dry eyes are the most common reason patients feel vision fluctuations,” says Dr. Chung. “Frequent lubrication ensures stable focus and comfort.”

After 1 Month: Fine-Tuning and Long-Term Protection

By the one-month mark, your cornea’s surface has healed, and your visual acuity should be stable — often 20/20 or better.

Your eye doctor will check:

Corneal clarity and contour
Tear film stability
Night vision and glare levels

At SNU Eye Clinic, we use topography-guided imaging to verify healing patterns — ensuring each eye’s optical surface remains perfectly smooth.

Long-Term Care Tips

Continue artificial tears as needed, especially in dry seasons or air-conditioned environments.
Wear sunglasses outdoors, even long-term — UV protection preserves both corneal and retinal health.
Avoid rubbing your eyes, ever. It’s one of the few habits that can cause long-term corneal stress.
Maintain regular checkups. We recommend visits at 1 week, 1 month, 3 months, 6 months, and annually thereafter.

Special Considerations for Contact Lens-Based Surgery (ICL)

If you’ve had an Implantable Collamer Lens (ICL) procedure rather than corneal laser surgery:

Avoid strenuous activity for 1 week.
Use prescribed anti-inflammatory drops longer (usually 3–4 weeks).
Do not press on your eyelids or sleep face-down.
Attend all postoperative pressure and vault checks.

The ICL lens is designed to rest gently behind your iris — proper monitoring ensures long-term compatibility and crystal-clear vision.

Common Sensations and When to Call Your Doctor

Normal sensations:

Mild dryness or grittiness
Occasional glare or halo in dim light (resolves as the cornea stabilizes)
Slight difference in sharpness between eyes

Contact the clinic immediately if you notice:

Increasing redness or pain
Sudden vision drop
Persistent light sensitivity or discharge

At SNU Eye Clinic, we have a 24-hour patient support line for postoperative concerns. Prompt evaluation prevents complications and gives peace of mind.

How Long Does Full Recovery Take?

SMILE: 3–5 days for daily function; full stability by 1–2 months
LASIK: 1–3 days for clear vision; stability by 1 month
ICL: 3–7 days for adaptation; full comfort by 1–2 months

“Our patients are often amazed by how quickly recovery happens,” says Dr. Chung.
“With the VisuMax 800 system and modern microincision techniques, most can return to normal life within days — not weeks.”

However, healing continues beneath the surface for several months. Proper lubrication and UV protection remain key even after your vision feels perfect.

Real Patient Experiences from SNU Eye Clinic

Case 1 – The Marathon Runner (SMILE PRO):
A 32-year-old fitness enthusiast resumed training within a week. By her one-month follow-up, she reported crystal-clear vision and no dryness — something she never achieved with contact lenses.

Case 2 – The Consultant (ICL):
A 41-year-old office worker spent 10 hours a day on screens. After Toric ICL implantation, he followed his drop schedule precisely and noticed sharp, stable vision even during long presentations.

Both cases show what we tell every patient: precision surgery delivers clear results — but disciplined aftercare ensures they last.
