SMILE is running on a femtosecond laser to reshape the cornea. This femtosecond laser is an extremely short-pulsed, near infrared laser often also used to create a LASIK flap. The laser’s high peak intensity over a very short pulse duration (within a few femtoseconds of time) allows it to create micro-precision single holes (bubbles) that forms together cuts or planes in the corneal tissue without affecting the surrounding tissue.
It takes less than 30 seconds for the laser to create a small lens-shaped piece of corneal tissue (called the lenticule) inside the cornea. The surgeon then removes the lenticule through a small incision outer part of the eye. This reshapes the cornea and corrects the refractive error.
Myopia (nearsightedness) & Astigmatism for now.
Hyperopia (farsightedness) will be treatable very soon.
The lack of flap creation in SMILE has some benefits, such as less risk of dry eye or flap complications. Recovery time is shorter after SMILE laser, it is about an hour. Patients return to their normal lives earlier after SMILE laser surgery.
Ultimately, both SMILE and LASIK are safe procedures.
The FDA has approved LASIK eye surgery for those 18 years and older, but most surgeon will encourage patients to wait until 21 years of age.
Initial Recovery from Surgery:
In SMILE surgery, the most advanced 3rd generation laser, fastest laser in the world, is used. Thanks to the smallest surface incision (2 mm), SMILE has the fastest recovery time. Many patients can turn back to their regular life after an hour from the surgery!
Full Visual Recovery:
Full visual recovery usually occurs within 1 month.
