|Laser Used||Only Femtosecond laser||Femto+/ Excimer Laser||Fmto/Excimer|
|Recovery||As i is flapless and bladeless, recovery is faster||Fast||Fast|
|Technique||Bladeless Flapless||Corneal flap is made with femtosecond or microkeratome (blade)||Same as LASIK|
While it is being said that Contura Vision is better than SMILE, the truth is Contura is just another name given to conventional topo guided LASIK.
Even though Contura Vision has technologically improved upon the traditional LASIK, it still creates the flap to improve the vision. Whereas, SMILE procedure does not require any flaps to correct the vision.
LASIK, as well as its variant Contura, create flaps of 18-20 mm size. SMILE has overcome this burden. It is a complete flapless procedure. That’s why the chances of suffering from the following flap-associated risk are lower when you avail SMILE to correct your vision.
Chances of flap dislocation: Both LASIK and Contura Vision procedure face this risk. The dislocation creates problems, like night glares, blurred vision, and severe pain. Being a flapless SMILE procedure do not face this risk.
Corneal Bio Mechanical Strength: Flap creation hampers the biomechanical strength of the cornea. Corneal Biomechanical properties are of more importance when it comes to laser refractive surgeries. SMILE is the only procedure that preserves corneal biomechanical properties better than LASIK.

DRY Eyes: Dry eyes are the biggest flap-associated risk. The studies show that SMILE causes lesser problems related to dry eye disease and supports a faster recovery of tear functions when compared to traditional LASIK and Contura Vision.

The Operation standards of SMILE s approved by the FDA. Across the world, more than 2 million eyes have been treated using this procedure.
All in all, SMILE is a better and safer option than the traditional LASIK and Contoura Vision.
