New Technique : SMILE Small-incision Femtosecond Lenticule Extraction
SMILE ( Small-incision Femtosecond Lenticule Extraction ) is a modification of the FLEx procedure. Unlike FLEx, SMILE requires no retractable flap. Instead of a full corneal flap to remove the intrastromal lenticule, SMILE make a small incision that only 4 - 5 mm in the mid-periphery of the cornea with the laser, and the lenticule is removed through this self-sealing incision.
- SMILE requires no retractable flap, eliminating the risk of flap dislocation and macrofolds, minimizing dry eye, enhancing corneal structural stability and offering more stable refractive outcomes than FLEx or LASIK.
- SMILE is a no-flap procedure, there is no risk of flap displacement from trauma to the eye after surgery.
How SMILE FLEx Works
Step 1. A keyhole incision, about 4 - 5 mm long is made in the cornea.
Step 2. The same machine cuts the corneal tissue beneath the surface.
Step 3. A probe is inserted to extract this lens-shaped corneal tissue without making further incisions.
