One of the most common questions in our Newport Beach consultations is how the recovery from SMILE Pro compares to LASIK. Many patients have heard that SMILE Pro is gentler or more comfortable, and they want to know if that means a faster or easier recovery overall.
The honest answer is that both recoveries are remarkably fast by the standards of medical procedures, but they have genuinely different profiles. SMILE Pro has a modest comfort advantage in the first few hours. WaveLight® Plus LASIK produces sharper vision faster, and by the morning after surgery its visual clarity is already ahead of SMILE Pro, an advantage that widens through the first week and holds through final stabilization.
If you are weighing the two procedures, the recovery difference is not which one is easier, it is which trade-off matches your life and your priorities.
Here is what actually happens, day by day.
The First 24 Hours
WaveLight® Plus LASIK
You leave the office with your vision already dramatically improved. Most patients describe it as looking through a thin layer of fog or water, not blurry enough to be disorienting, but not perfectly sharp yet. The improvement from your preoperative vision is usually immediate and obvious.
The first 2 to 4 hours are the least comfortable window. Patients commonly experience a gritty or sandy sensation, mild burning, tearing, and light sensitivity. This is driven by the partial-thickness incision at the edge of the LASIK flap. The epithelium heals over that incision within about 2 to 4 hours, after which comfort improves significantly. We ask you to go home, keep your eyes closed, and rest as much as possible. Most patients nap through the worst of it.
By the evening of surgery, most patients can already see well enough to watch TV or navigate the house without glasses. Vision continues to clear steadily. By the next morning, the majority of WaveLight® Plus patients wake up and can read their alarm clock across the room, often the first moment many patients get emotional about the result.
SMILE Pro
Initial vision after SMILE Pro is typically a bit foggier than LASIK on day one. The reason is structural: SMILE Pro extracts a small lenticule of corneal tissue through a tiny incision, and the stromal surface takes a few hours longer to settle into a smooth optical configuration than a LASIK flap.
Both SMILE Pro and LASIK create a partial-thickness corneal incision, so both procedures produce some burning, tearing, and light sensitivity for the first 2 to 4 hours while the epithelium heals over the edge. SMILE Pro’s incision is smaller (2 to 4 mm) than the LASIK flap edge, which some patients report as marginally less uncomfortable in that first window, but the difference is modest and short-lived. By day one, comfort is similar for both procedures.
By the next morning, SMILE Pro patients typically see well enough for basic function, but the visual clarity is usually behind LASIK at the same time point.
The first 24 hours verdict: Vision clarity favors LASIK. Comfort is similar for both procedures, with a modest and short-lived edge to SMILE Pro due to the smaller incision. Both are well tolerated.
Day 1 Post-Op Visit
Both procedures require a follow-up exam the morning after surgery. At Feinerman Vision, Dr. Feinerman personally follows up the evening of surgery and sees every patient again in the morning.
WaveLight® Plus LASIK
The day 1 visit checks flap position and measures visual acuity. Most WaveLight® Plus patients are already at 20/20 or better uncorrected. Based on the Kanellopoulos 2025 head-to-head data, 98% of WaveLight® Plus eyes achieve 20/12.5 or better by the 3-month mark, with the majority of that improvement showing up by the end of week 1.
Most patients are cleared to drive after this visit.
SMILE Pro
Day 1 visual acuity for SMILE Pro typically lags behind LASIK by about one line on the eye chart. This is not a complication, it is the expected healing trajectory. Most SMILE Pro patients will reach 20/25 or 20/20 by day 2 or 3.
Driving clearance is usually given at day 1 or 2, depending on visual acuity.
Days 2 to 3
WaveLight® Plus LASIK
By day 2, most patients feel essentially normal. The gritty sensation is gone or minimal. Vision is crisp in good lighting. Many patients return to work on day 2, especially if their job does not involve heavy screen use.
Common lingering symptoms at this stage: occasional dryness, mild fluctuation in vision during long screen sessions, sensitivity to bright sunlight outdoors.
Activity-wise: walking and light daily activities are fine. No eye rubbing, no swimming, no eye makeup.
SMILE Pro
By day 2 or 3, SMILE Pro patients experience meaningful visual improvement. Most are driving, reading, and working by this point. Comfort is essentially equivalent to LASIK at this stage, both procedures feel similar in terms of sensation from day one onward.
Vision is typically still slightly softer than it will be at week 2. SMILE Pro’s characteristic recovery pattern is a gradual, smooth upward curve in visual clarity rather than the fast spike LASIK shows.
The First Week
WaveLight® Plus LASIK
By the one-week follow-up, most patients are at or very close to their final refraction. Dryness symptoms may peak around this window, especially for patients with pre-existing borderline dry eye. Preservative-free lubricating drops handle it for nearly everyone. For the small number of patients whose dryness is not fully relieved by artificial tears, Dr. Feinerman provides complimentary samples of a twice-daily prescription dry eye medication such as Vevye or Xiidra.
Light exercise (walking, stationary cycling, yoga) is typically cleared at this point. Screen use is fine with the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds).
Restrictions still in place: no contact sports, no swimming, no hot tubs, no direct water pressure on the eyes, no rubbing.
SMILE Pro
By the end of week one, SMILE Pro patients typically achieve 20/20 or close to it, though contrast sensitivity and higher-order aberration metrics remain softer than comparable WaveLight® Plus outcomes. The visual clarity gap established on day one persists and, based on the Kanellopoulos 2025 head-to-head data, is already measurable by this point.
Activity restrictions for SMILE Pro at week one are similar to LASIK: light exercise is fine, no swimming, no contact sports, no eye rubbing. There is no flap to dislodge after SMILE Pro, but the eye rubbing restriction is still enforced for healing reasons.
Weeks 2 to 4
WaveLight® Plus LASIK
This is when most patients describe their vision as better than it has ever been. The early fluctuations fade. Contrast sensitivity is sharp. Night driving becomes comfortable, and with WaveLight® Plus ray-tracing personalization, patients typically report significantly fewer halos and starbursts than older LASIK platforms produced.
Full workouts, running, and most normal activities are cleared. Swimming is usually cleared between weeks 2 and 4.
SMILE Pro
SMILE Pro patients reach their functional vision plateau around this window. Most are fully back to normal activities. Any residual dryness tends to be mild and manageable with lubricating drops.
By this window, the WaveLight® Plus visual clarity lead established in the first days has widened meaningfully, particularly on contrast sensitivity and higher-order aberration metrics. SMILE Pro’s visual stability curve continues to tighten through month 2 and 3, meaning final visual sharpness arrives later and at a lower peak than WaveLight® Plus.
Months 1 to 3
Both procedures reach their final stable result in this window. By month 3:
- WaveLight® Plus LASIK: Per FDA pivotal data (He C, Bala C. J Cataract Refract Surg 2023;49(11):1140-1146), 100% of eyes achieve 20/20 or better uncorrected, 89% achieve 20/16, and 50% achieve 20/12.5. Contrast sensitivity is typically better than preoperative with glasses.
- SMILE Pro: Per published data, 92% of eyes achieve 20/20 or better, with typical efficacy and safety indices around 0.93 and 1.00 respectively.
Dry eye symptoms continue to resolve. By the 3-month mark, most patients have forgotten they had surgery. Long-term follow-ups happen at month 3 and 6, with final visual stability documented around month 6.
SMILE Pro Recovery vs. LASIK Recovery: Side-by-Side Comparison
| Recovery Milestone | WaveLight® Plus LASIK | SMILE Pro |
|---|---|---|
| Functional vision | Within hours | Day 2 to 3 |
| Drive | 24 hours | 48 to 72 hours |
| Return to desk work | Day 1 to 2 | Day 2 to 3 |
| First-day comfort | Mild gritty/burning for 2 to 4 hours | Similar: mild burning and tearing for 2 to 4 hours |
| 20/20 or better | Day 1 for most | End of week 1 for most |
| Light exercise | Day 2 to 3 | Day 2 to 3 |
| Swimming | Week 2 to 4 | Week 2 to 4 |
| Contact sports | Week 4+ | Week 2 to 4 |
| Dry eye risk | Higher weeks 1 to 4, resolves by 3 months | Lower weeks 1 to 12, equalizes by 12 months |
| Final vision stability | Month 1 to 3 | Month 1 to 3 |
A note on the contact sports and dry eye rows: for patients whose work or sport carries ongoing risk of direct eye trauma, Dr. Feinerman typically recommends PRK rather than either procedure above. For patients with meaningful dry eye risk, he typically recommends evaluating EVO ICL™, which removes no corneal tissue and leaves the corneal nerves largely undisturbed. In a published study of patients 5 to 15 years after surgery, laser vision correction patients showed significantly higher rates of tear hyperosmolarity, a marker of tear film instability, than non-surgical controls, while implantable collamer lens patients showed no difference from controls (Gjerdrum B, et al. Clin Ophthalmol. 2020;14:269-279).
Which Recovery Profile Is Better for You?
Lean toward WaveLight® Plus LASIK if:
- You want the sharpest possible vision as fast as possible
- You need to drive or work the day after surgery with full visual clarity
- You want personalized ray-tracing correction for superior night vision and contrast sensitivity
- You are prepared to manage a few hours of mild gritty sensation and dryness for a faster overall visual result
Where SMILE Pro Fits
As a factual matter, SMILE Pro is approved for myopia with mild astigmatism within a defined treatment range, and its advocates highlight the flapless technique as a potential advantage for patients who simply prefer a procedure without a flap. Choosing it on that basis means accepting a somewhat softer visual trajectory than WaveLight® Plus LASIK, as the comparison above shows.
For the two situations most often cited in favor of SMILE Pro, our practice position points elsewhere:
- If your occupation or lifestyle carries meaningful ongoing risk of direct eye trauma (for example, active-duty military or combat sports), Dr. Feinerman typically recommends PRK, a surface procedure that creates no flap at all.
- If you have moderate to severe pre-existing dry eye, Dr. Feinerman typically recommends evaluating EVO ICL™. EVO ICL™ removes no corneal tissue and leaves the corneal nerves largely undisturbed.
For most patients in Orange County, the WaveLight® Plus LASIK recovery is the better fit because the visual quality advantage is significant and lasting. For patients with ongoing eye-trauma exposure or meaningful dry eye risk, Dr. Feinerman typically recommends PRK or EVO ICL™ respectively, and at Feinerman Vision we make the recommendation based on your individual measurements and priorities, not on which procedure we prefer.
What Both Recoveries Share
Regardless of which procedure you choose, the foundations of recovery are identical:
- Use your prescribed drops exactly as instructed
- Do not rub your eyes
- Wear the protective shields for the first night
- Keep water, soap, and chemicals out of your eyes for the first week
- Wear UV-blocking sunglasses outdoors for the first month
- Attend every follow-up visit (day 1, week 1, month 1, month 3)
- Call the office for anything that feels off, there is no question too small

Frequently Asked Questions
Which procedure has the faster visual recovery?
WaveLight® Plus LASIK typically produces sharper vision within hours of surgery, while SMILE Pro typically takes 2 to 3 days to reach comparable clarity. By the morning after surgery, WaveLight® Plus visual clarity is already ahead of SMILE Pro, and that lead widens through the first week and holds through final stabilization.
Is SMILE Pro more comfortable than LASIK in the first day?
Only marginally. Both procedures create a partial-thickness corneal incision that produces some burning, tearing, and light sensitivity for the first 2 to 4 hours while the epithelium heals over the edge. SMILE Pro’s incision is smaller, which some patients report as slightly less uncomfortable, but the difference is modest and short-lived. By day one, comfort is similar for both procedures.
When can I drive after each procedure?
Most WaveLight® Plus LASIK patients are cleared to drive within 24 hours. Most SMILE Pro patients are cleared at day 2 to 3. The exact timing depends on measured visual acuity at the day 1 follow-up.
When can I return to work after each procedure?
WaveLight® Plus LASIK patients typically return to desk work at day 1 or 2. SMILE Pro patients typically return at day 2 or 3. Jobs with heavy screen use, dusty environments, or physical labor may require an additional day or two.
Do both procedures cause dry eye?
Yes, though the timing differs. LASIK causes more dry eye symptoms in the first 1 to 3 months because flap creation temporarily disrupts more corneal nerves. SMILE Pro causes less early dry eye. By 12 months, published meta-analyses show no significant difference between the two procedures in dry eye incidence or severity. For patients with meaningful pre-existing dry eye, Dr. Feinerman typically recommends evaluating EVO ICL™ instead. EVO ICL™ removes no corneal tissue and leaves the corneal nerves largely undisturbed.
When can I exercise after each procedure?
Light exercise (walking, yoga, stationary cycling) is typically cleared at day 2 to 3 for both procedures. Full workouts are cleared at week 1 to 2. Swimming typically waits until week 2 to 4. Contact sports require additional precautions.
Do I need to wear eye shields at night after SMILE Pro?
Not strictly required for structural protection because there is no flap to dislodge, but most surgeons still recommend shields for the first night to prevent accidental rubbing during sleep. After LASIK, shields are more important because the flap is still bonding to the underlying cornea.
Which procedure does Feinerman Vision recommend?
For most refractive candidates in Orange County, WaveLight® Plus LASIK is the procedure that delivers the best combination of visual outcome, recovery speed, and enhancement pathway simplicity. A consultation at Feinerman Vision includes a full candidacy assessment for all current refractive options.
