If you have been thinking about laser vision correction but want something simple, safe, and fast, there is now a new way to see clearly — and it is changing how people experience life after vision correction. It is called SMILE, short for Small Incision Lenticule Extraction.
At Khanna Vision Institute, Dr. Rajesh Khanna offers SMILE as one of the most advanced and gentle forms of laser eye surgery. It provides precise correction for nearsightedness and astigmatism, all through a tiny incision. This breakthrough approach is helping people across California see the world with clarity, comfort, and confidence.
1. What Is SMILE
SMILE is the latest generation of laser vision correction. It uses a femtosecond laser to reshape the cornea — the clear, front part of your eye — without creating a large surface flap as in traditional LASIK.
The procedure involves making a very small incision, about 2 to 3 millimeters wide. Inside the cornea, the laser creates a thin lens-shaped piece of tissue, known as a lenticule, which is then gently removed. This changes the curvature of the cornea so that light focuses correctly on the retina, restoring clear vision.
Because the incision is so small, the healing process is fast, comfortable, and low risk.
2. How SMILE Is Different from LASIK
Both SMILE and LASIK are effective vision correction procedures, but SMILE is even less invasive.
| Feature | SMILE | LASIK |
|---|---|---|
| Incision Size | About 2–3 mm | About 20 mm |
| Corneal Flap | None | Required |
| Recovery Time | 1–2 days | 2–3 days |
| Dry Eye Risk | Lower | Slightly higher |
| Suitable For | Nearsightedness and astigmatism | Nearsightedness, farsightedness, astigmatism |
By eliminating the need for a corneal flap, SMILE preserves the natural strength of the eye and reduces dry eye symptoms. This makes it a great choice for people with active lifestyles or mild dryness issues.
3. Who Can Benefit from SMILE
SMILE is designed for adults who want clear vision without glasses or contact lenses. You may be a good candidate if you:
- Are at least 18 years old
- Have stable vision for at least one year
- Are nearsighted up to -10.00 diopters
- Have astigmatism up to -3.00 diopters
- Have healthy corneas and no active eye diseases
People who are not eligible for LASIK because of corneal thickness or dryness may still qualify for SMILE.
Dr. Khanna uses detailed imaging and diagnostic testing to confirm eligibility and design a fully customized treatment plan.
4. The SMILE Procedure: Step-by-Step
At Khanna Vision Institute, the SMILE procedure is simple, precise, and comfortable.
- Preparation — Numbing drops are applied to the eyes for comfort.
- Laser Creation — The femtosecond laser creates the lenticule inside the cornea and a small incision on the surface.
- Lenticule Removal — Dr. Khanna gently removes the lenticule, allowing the cornea to reshape naturally.
- Healing — The small incision seals on its own without stitches.
The entire process takes about 10 to 15 minutes for both eyes. Most patients notice clearer vision within 24 hours.
5. Advantages of SMILE
Fast Recovery
Because SMILE uses a smaller incision, healing is quicker and more comfortable. Most patients return to work or normal activities in one to two days.
Minimal Dryness
With fewer corneal nerves affected, post-surgery dryness is less common than with traditional LASIK.
Flap-Free Safety
There is no corneal flap, reducing risks related to dislodgement or trauma.
Long-Term Stability
The structural integrity of the cornea remains stronger, offering stable results for years.
Great for Active Lifestyles
SMILE is ideal for athletes, travelers, and those who enjoy outdoor or high-movement activities.
6. Results and Patient Experience
Patients who undergo SMILE often describe their vision as crisp and natural. Many achieve 20/20 vision or better within a day or two after the procedure.
The comfort level during and after surgery is high, and there is minimal light sensitivity or discomfort.
At Khanna Vision Institute, patients consistently report high satisfaction, appreciating both the clear visual results and the gentle recovery experience.
7. Safety and Technology
SMILE is an FDA-approved procedure performed with the ZEISS VisuMax femtosecond laser, one of the most advanced laser systems in the world. It allows for ultra-precise incisions and consistent results.
Dr. Khanna combines this technology with his extensive refractive surgery experience to ensure every patient receives the highest standard of care.
Safety protocols, detailed diagnostics, and post-operative monitoring are all part of the comprehensive treatment process at Khanna Vision Institute.
