What is SMILE laser eye surgery?

If you’re considering vision correction, you may have heard about SMILE laser eye surgery. But what is it, and how does it compare to LASIK? Here’s everything you need to know about this modern procedure and why it’s an excellent option for many patients.

What is SMILE laser eye surgery?

SMILE (Small Incision Lenticule Extraction) is a minimally invasive laser eye surgery designed to correct myopia (nearsightedness) and astigmatism. Unlike LASIK, which involves creating a flap in the cornea, SMILE removes a small piece of corneal tissue (lenticule) through a tiny incision, reshaping the eye to improve vision.

How does SMILE work?

  1. Laser creates a lenticule – A femtosecond laser precisely creates a disc-shaped piece of corneal tissue inside the eye
  2. Lenticule removal – The surgeon removes this tissue through a tiny incision, reshaping the cornea to correct vision
  3. Vision correction – The eye heals naturally without the need for a large flap, offering a quicker and more comfortable recovery.

Benefits of SMILE surgery

  1. Minimally invasive
    SMILE requires only a 2-4mm incision, compared to the larger flap used in LASIK, reducing the risk of complications
  2. Flap-free procedure
    Since SMILE doesn’t create a corneal flap, it minimises the risk of flap-related issues and is ideal for patients with an active lifestyle
  3. Fast recovery time
    Most patients experience clear vision within a few days, with minimal discomfort and a lower risk of dry eye symptoms
  4. Reduced risk of dry eye
    SMILE preserves more corneal nerves than LASIK, reducing the likelihood of post-surgery dry eye syndrome
  5. High precision and safety
    SMILE uses advanced femtosecond laser technology for precise corrections, making it one of the most accurate vision correction procedures available.

Who is a candidate for SMILE?

SMILE is best suited for people with:

  • Mild to moderate myopia (-1.00 to -10.00 D)
  • Stable prescriptions for at least a year
  • Healthy corneas with no severe eye conditions
  • Astigmatism up to -5.00 D.

How does SMILE compare to LASIK?

Feature SMILE LASIK
Flap creation No Yes
Recovery time A few days 24 hours
Risk of dry eye Lower Higher
Treats hyperopia No Yes
Suitability for active lifestyles Excellent Good

Hi, I’m Daemon McClunan

I’m proud to be the founder of both Atlantic Eye Centre, an eye specialist centre, and LIQID Medical Pty, a biotech company. My passion for research and innovation has led me to create four patented devices, and receive awards during my specialist training.

With a medical degree from Stellenbosch University, a specialist degree from the University of Cape Town, and experience working in Laser Eye Surgery centres in Canada, Germany, India and London, I’m dedicated to providing dedicated, patient-centred care.

Beyond the clinic, I’ve embarked on humanitarian missions, travelling over 15,000km by motorbike to provide rural eye screenings. In my downtime, I love mountain biking, diving, and spending quality time with my family.

My goal is for every patient to feel genuinely informed, comfortable, and well cared for – from their first conversation right through to their last post-operative visit.
