Femtosecond Lasik: Why You Might Need It

eye clinic dubai

The Femto-LASIK is a revolutionary procedure in the field of corrective eye surgeries. It is a refractive error treatment in which a femtosecond laser is used to correct the errors. It is a bladeless and painless option to correct vision. 

The Femto-Lasik is a type of corneal refractive laser surgery, and it uses a femtosecond laser to form a thin corneal flap, which will reshape your cornea and then correct the refractive errors. There are a lot of benefits to this procedure as it is bladeless, quick, and precise. 


  • In this treatment process, the top layer of the cornea is removed circularly and then folded aside. While the conventional procedures use a blade and a microkeratome to form the corneal flap, the Femto-LASIK uses a femtosecond laser to create the corneal flap.
  • The femtosecond laser discharges energy at a depth of the cornea. This creates numerous bubbles within the determined area. 
  • The ophthalmologist will then detach a thin corneal lamella from the determined area. 
  • The femtosecond laser allows the surgeon to form a thin flap safely. 
  • Towards the end, the flap is repositioned, allowing it to heal and adhere naturally without the use of stitches. 


The patient requirements include:

  • The patient must be 18 years or older.
  • The patient must have had a stable spectacle power for the last two years. 
  • The patient must have a corneal thickness of 470 microns.
  • The patient must have an adequate corneal topography.
  • The patient should have good ocular health.
  • The patient should not be pregnant or breastfeeding. 

Advantages of Femtosecond Laser

There are numerous benefits to femtosecond laser, and this makes it an ideal choice for treatment. 

The different advantages of femtosecond laser include:

Lesser flap related complications: There are many things that can go wrong while using a mechanical blade. Mechanical blades can malfunction when there is a loss of power, jamming of mechanical parts, loss of suction during the pass, and also if there is an operator error. Unusually shaped eyes are also at the risk of irregular flap creation. However, these errors are highly unlikely to occur when using a femtosecond laser.

Lower chances of epithelial growth: There are greater chances of developing an epithelial growth while using a microkeratome rather than a femtosecond laser. The femtosecond laser allows the surgeon to precisely create the side cut angle, and this inhibits the passage of epithelial cells.

Patient preference: The Femto-LASIK procedure is the preferred treatment choice among patients due to greater precision and painless process. The aftercare is also relatively simple. 

Improved visual outcomes: The best part of the Femto-LASIK procedure is that it delivers accurate results in very little time. 


The aftercare measures include:

  • Avoid rubbing the operated eye.
  • You have to wear an eye shield while sleeping to avoid moving the flap. Make sure to wear the eye shield for at least one week, to fasten the healing process and prevent discomfort. 
  • Follow the surgeon’s instructions and use the prescribed eye drops to prevent infection and to control dryness. 
  • Avoid engaging in strenuous contact sports like swimming, football, and basketball for at least two weeks. 

Our ophthalmologists aim to provide world-class treatment, and the invention of the femtosecond laser has simplified the process of vision correction.
