SMILE is the next generation of laser eye surgery. No flap, no blade, less dry eye, stronger cornea. It offers everything LASIK does β permanent freedom from glasses β with one important difference: the surface of the eye is barely touched.
How the two procedures compare on the key factors
The entire procedure takes about 10 minutes for both eyes. Here is exactly what happens.
Eye drops numb both eyes completely. No injections. You are relaxed and awake throughout.
A tiny disc of corneal tissue β called a lenticule β is created inside the cornea. This takes few seconds per eye. You feel nothing.
Through a 2β4mm incision (much smaller than LASIK), the lenticule is gently removed. The cornea reshapes naturally as a result.
You rest for an hour and go home. Vision improves significantly within 24β48 hours.
In LASIK, a thin flap is created on the corneal surface. The laser reshapes the tissue underneath, then the flap is repositioned. The flap never fully re-attaches to its original strength.
In SMILE, no flap is created at all. The correction happens entirely inside the cornea through a tiny incision. The surface remains largely intact. This means:
Fewer corneal nerves are cut β so dry eye after surgery is significantly less common than with LASIK.
The cornea retains more structural integrity β important for people in physically demanding roles, sports, or martial arts.
No flap-related complications β which, while rare with modern LASIK, are simply not possible with SMILE.
Six reasons why patients choose SMILE β especially those who were told they were not suitable for LASIK.
Fewer corneal nerves are disrupted during SMILE. Post-operative dry eye β one of the most common complaints after LASIK β is significantly less frequent with SMILE.
With no flap and a smaller incision, the cornea retains more of its natural structural strength. Ideal for sportspeople, military personnel, and physically active patients.
Flap displacement β though rare with modern LASIK β is simply not possible with SMILE. The absence of a flap removes an entire category of potential complications.
Patients who were told their corneas are too thin for LASIK may be candidates for SMILE. A proper assessment will confirm suitability.
Visual outcomes with SMILE are equivalent to LASIK. Most patients achieve 6/6 vision or better. The quality of vision is sharp, clear, and stable.
Few seconds of laser per eye. Painless under anaesthetic drops. Both eyes done in a single sitting. Vision begins improving within 24β48 hours.
SMILE is not for everyone β and neither is LASIK. Dr. Sobti will recommend the right procedure based on your corneal measurements, prescription, and lifestyle. Here is a general guide.
