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.

The Advantages Of SMILE FLEx

  1. 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.
  2. 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.
