If you've ever imagined waking up and seeing clearly without reaching for your glasses or contact lenses, SMILE Eye Surgery might sound like the perfect solution.
SMILE — which stands for Small Incision Lenticule Extraction — is one of the most advanced and minimally invasive laser vision correction options available today. It's quick, flap-free, and offers fast recovery with long-lasting results.
But is SMILE the right procedure for you?
At Khanna Vision Institute, Dr. Rajesh Khanna evaluates each patient carefully to determine if SMILE is the best match for their eyes and lifestyle. In this article, we'll explore what makes someone an ideal candidate for SMILE and how it differs from other vision correction procedures.
1. What Is SMILE Eye Surgery? (A Quick Refresher)
SMILE is a next-generation laser eye surgery that corrects nearsightedness (myopia) and astigmatism using a tiny laser incision, instead of creating a large flap like in LASIK.
A femtosecond laser creates a small, disc-shaped piece of tissue (called a lenticule) inside the cornea. This lenticule is then gently removed through a small opening — about the width of a pen tip.
This reshaping allows light to focus correctly on your retina, restoring clear vision.
The result?
Sharper vision, minimal discomfort, and quick healing — all achieved with a smaller incision and no flap.
2. SMILE vs. LASIK — What's the Difference?
While both SMILE and LASIK are laser-based procedures, they have key differences:
| Feature | SMILE | LASIK |
|---|---|---|
| Incision Size | Tiny (2–3 mm) | Larger (20 mm flap) |
| Flap Creation | No flap | Creates a corneal flap |
| Corneal Strength | Better preserved | Slightly reduced |
| Dry Eye Risk | Lower | Slightly higher |
| Recovery Time | Fast | Fast |
| Ideal for | Active lifestyle, moderate to high myopia | Broad vision correction needs |
For many people — especially those who play sports or have dry eyes — SMILE offers a safer and gentler option.
3. Who Is an Ideal Candidate for SMILE Eye Surgery?
At Khanna Vision Institute, Dr. Khanna uses advanced diagnostic tools to determine candidacy. But in general, you may be a great candidate for SMILE if:
You Are 18 Years or Older
Your eyes should be fully developed before laser vision correction.
You Have Stable Vision
Your prescription should not have changed significantly (more than ±0.5 diopters) for at least one year.
You Are Nearsighted or Have Astigmatism
SMILE is FDA-approved to correct up to:
- -10.00 diopters of myopia (nearsightedness)
- -3.00 diopters of astigmatism
If you have farsightedness (hyperopia), LASIK or EVO ICL may be better options.
You Have Healthy Eyes
Conditions like cataracts, glaucoma, keratoconus, or corneal scarring can affect eligibility.
You Want a Flap-Free Procedure
If you prefer a laser correction without the flap creation used in LASIK, SMILE is ideal.
You Have an Active Lifestyle
Athletes, military personnel, and people who do outdoor or contact sports benefit from SMILE's added corneal strength and low risk of flap complications.
4. Who Might Not Be a Good Candidate for SMILE?
Even though SMILE is safe for most adults, it's not right for everyone. You may not be an ideal candidate if:
- Your corneas are too thin
- You have severe dry eyes or eye infections
- You're pregnant or breastfeeding (temporary vision changes)
- You have autoimmune conditions affecting healing
- You have extreme prescriptions beyond SMILE's approved range
In such cases, Dr. Khanna may suggest alternatives like EVO ICL, PRK, or Presby-LASIK, based on your vision goals and eye health.
5. What Are the Benefits of Choosing SMILE Eye Surgery?
Patients choose SMILE for its comfort, precision, and rapid recovery. Some of its major benefits include:
No Flap, Less Dryness
Since SMILE doesn't involve cutting a corneal flap, it leaves most surface nerves untouched — reducing dry eye symptoms.
Fast and Gentle Recovery
Most people return to work and normal activities in 1–2 days.
Excellent Visual Outcomes
Clinical studies show over 98% of SMILE patients achieve 20/25 vision or better.
Long-Term Corneal Stability
SMILE preserves more of the eye's natural structure, maintaining strength even years later.
Less Risk of Dislodgment
No flap means fewer risks for people with active or outdoor lifestyles.
6. A Real Example — How SMILE Helped Jessica Schmidt
Professional softball player Jessica Schmidt wanted to improve her performance on the field but struggled with glasses. After consulting with Dr. Khanna, she was found to be a perfect candidate for SMILE.
Just days after her procedure, Jessica reported sharper vision, better reaction time, and new confidence — all without worrying about contacts during games.
Her experience shows how SMILE not only improves vision but can also enhance everyday life and performance.
