What are the Limitations?

PRK
Photorefractive Keratectomy

LASIK
Laser-assisted in-situ keratomileusis

SMILE
Small incision lenticule extraction
Surface ablation surgery
Flap surgery
Keyhole, flapless surgery

The outer thin corneal layer called the epithelium is removed with an alcohol solution.

The underlying tissue is then reshaped with the excimer laser.

Femto –LASIK is used to create a precise and predictable flap, blade free.

A hinged piece of corneal tissue is created in the outer corneal layer.

The flap is folded back and the underlying tissue is sculpted with a laser called tissue ablation.

A thin piece of tissue called the lenticule is created inside the cornea and is removed through a small keyhole incision.

  • Suitable for patients with thin corneas
  • No flap created no risk of flap related complications (ie. Flap detachment or displacement)
  • Lower rate of infection as compared to LASIK
  • Cost effective least expensive of all laser procedures offered
  • Quick Visual recovery
  • Most frequently performed refractive surgery treatment standard for past 20 years
  • Widely available
  • Minimally invasive due to keyhole incision 2-4 mm
  • Gentle and pain free
  • No flap- low incidence of dry eyes and low risk of infection
  • Better suitability for patients who suffer from contact lens intolerance and dry eye symptoms
  • Pain and a long healing process
  • Stabilization of vision potential for haze or milky vision during recovery
  • Sounds and odours during the procedure
  • Flap complication: -infection
    -flap dislocation
    -flap detachment
  • High incidence of dry eye and reported foreign body sensations
  • Sounds and odour during the procedure
  • Not available for hyperopic ( farsighted patients)
  • No long term studies
  • Side effects are rare but can’t be ruled out
