WHAT IS SMILE?
SMILE is the newest technology in correcting myopia and astigmatism, by removing a thin layer from the corneal stroma through a small 2-3 mm incision, using femtosecond laser.
SMILE procedure provide quick and painless visual improvement, and the risk of developing dry eyes is negligible, due to the small incision made on the surface of cornea, in comparison to the large incision made in LASIK surgery.

IS SMILE EYE SURGERY SAFE?
Every procedure is associated with potential complications and SMILE is not an exception. However since this is a flap-less procedure, it indicates that all complications associated with the corneal flap, as in the case of LASIK, would be excluded from SMILE.
The most encountered complication with SMILE is the lenticule misdissection, which could lead to the procedure being aborted. With newer techniques emerging in lenticule dissection, however, this complication is becoming less frequent.
Difficult lenticule extraction could be encountered during the surgery in 9%. This could be related to the laser energy setting. It usually leads to an extended time of surgery and delayed visual recovery of up to one month due to corneal oedema. With continuing improvement of energy setting, this complication is becoming less encountered
Cap tears could be encountered in 1%. The cap is the anterior part of the cornea overlying the lenticule. Difficulty with delivering the lenticule could result in cap tears. If this complication happened, a bandage contact lens will be used to faster the healing process. The visual recovery might be delayed for up to one month, however, the final visual outcome is no less than uneventful surgery
Retained lenticule is also related to difficult lenticule dissection and could be encountered in 3%. If the visual outcome was suboptimal, further refractive surgery, such as LASIK, could apply three months later with a very good outcome.
The recurrence of short-sightedness could be encountered in 2.2% to 2.9% after the SMILE procedure and this is comparable, or slightly lower, than those reported for LASIK
Enhancement could be achieved with further refractive surgery like LASIK or PRK.
Most of the SMILE complications are related to difficult lenticule extraction, however, these complications would be less with further improvement of the laser setting.
Even if a complication happens, the visual outcome is still excellent, albeit with delayed recovery.
HOW LONG IS THE RECOVERY TIME AFTER SMILE?
On the first day following SMILE procedure, 55% of the patient will achieve 20/20 vision. This percentage would increase to 80% at one week, 93% at one month, and 96% at three months.
Patients may notice reduced quality of vision on the first day like glare and haloes, which is due to the postoperative corneal swelling. As the corneal swelling settles down, the quality of vision will get better and over the following three months there might be further improvement in the visual acuity.
HOW OLD DO YOU HAVE TO BE TO GET SMILE?
Like other laser refractive surgery patient should be 21 year-old and abov
