SMILE is the most advanced, flapless, bladeless, all-femtosecond laser procedure that is currently available only on the Carl Zeiss Visumax laser platform. It can correct myopia of upto -10 D and astigmatism of upto 5D at present.

It involves carving out a lenticule or disc in the middle of the cornea with a femtosecond laser and then removing this lenticule out through a laser-made keyhole incision.

STEP BY STEP PROCEDURE

STEP1

step1- relex smile

The refractive lenticule and small incision are created inside the intact cornea all in one step

STEP2

step2- relex smile

The lenticule subsequently removed through this small incision, leaving the remainder of the superficial cornea intact

STEP3

step3- relex smile

Removing the lenticule changes the shape of the cornea, thereby achieving the desired refractive correction

SMILE versus LASIK

Since a corneal flap is not made in the procedure, it does away with a lot of risks and complications of flap creation like:

  • Dry eye is significantly lesser with SMILE than with LASIK
  • Corneal nerves and corneal sensations are better preserved with SMILE than with LASIK
  • Flap complications like folds in the flap, displacement of the flap, buttonholes or complete cutting of the flap do not occur with SMILE
  • The strength and structure of the cornea is preserved better with SMILE than with LASIK. The flap made in LASIK weakens the front of the cornea and cannot contribute to its strength in the future. A flapless procedure like SMILE is preferred for moderately high errors to provide better strength to the cornea in the longterm.
  • Minimally invasive- 2 mm wound compared to 20 mm wound in LASIK. This results in more rapid recovery to routine activities

Procedure:

  • Takes 15 minutes for both eyes
  • Numbing drops/ topical anesthesia used- no injection, no patch, no pain, no stitches, no blood
  • One has to lie down for the duration of the procedure
  • Eye is kept open and cannot be closed by the patient
  • Doctor’s instructions are to be followed during the procedure
  • Right eye is followed by left eye treatment
  • Procedure is over before you realize, with no pain!
  • Goggles are given

  • Expect to see blurry and experience some watering, irritation on the day of treatment
  • It gets better the next day
  • Vision is usually 90-95% on the next day and gets better over next 3-4 days
  • Eye Drops for 2 weeks only
  • No water in the eyes and head bath for 3-4 days
  • Protective sunglasses outdoors for a week
  • Side-effects: Glare, light sensitivity, night vision blurry

These are common and gradually get better over few weeks.

FREQUENTLY ASKED QUESTIONS
