Femto-LASIK

Femto-LASIK

Introduction

Femto-LASIK is a type of corneal refractive laser surgery which is widely performed. It is the abbreviation of Laser-Assisted in Situ Keratomileusis. It is a surgical procedure that uses laser to reshape the cornea to correct the refractive error with a thin flap in the cornea.

Procedure

Step 1
Cornea flap is created and lifted.

Step 2
An Excimer laser is used to correct the refractive error.

Step 3
The flap is repositioned and allowed to heal and adhered naturally without stitches

Patient Criteria
  • 18 years old and above
  • Power of spectacles must be stable for at least 2 years
  • Minimum corneal thickness of 470 micron
  • Normal corneal topography
  • Healthy eyes
  • Neither pregnant nor breastfeeding
Benefits
  • Bladeless
  • Quick recovery
  • Well-established procedure
Creating LASIK Flaps

Fully Laser Automated (Femto-LASIK) VS Blade LASIK

In the early years of LASIK surgery, manual blade system known as microkeratomes were used to create the corneal flap. The flap was created to allow exposure of the deeper layer of the cornea to the Excimer laser that reshapes the cornea. The development of Femtosecond laser technology has revolutionised flap creation; it allows the procedure to be a bladeless procedure with its own advantages. Bladeless procedures provide a better experience for the patients and better comfort.

Bladeless / Femto-LASIK
  • Uses Femtosecond laser systems to create the corneal flap
  • Safely create even flaps as thin as 100 microns
Blade LASIK
  • Mechanical microkeratome use high-precision oscillating-blade systems that dock to a suction ring to create a lamellar corneal flap
  • Flap thickness may vary throughout the flap

Post-operative care

After surgery, it is recommended to:

  1. Not rub the operated eye.
  2. Wear an eye shield while sleeping for a week to avoid moving the flap.
  3. Compliance towards prescribed eye drops usage following the surgery to prevent infection and control dryness.
  4. Avoid swimming for a month and strenuous contact sport for at least two weeks.
