Femtosecond Laser Surgery

Overview:

  • 100 times greater precision than manual surgery.
  • Predictability of results exceeds 98%.
  • Utilized for over a decade, known for its speed and safety.

What is the Femtosecond Laser?

  • The most precise laser in eye surgery, operating at a millionth of a second.
  • It creates micro-incisions pre-designed by the surgeon with micrometric precision via computer, minimizing dependence on manual skills.
  • Reversible technology: uses minimal energy to separate tissue without burning or transferring heat to the cornea.
  • Uses infrared light to ensure precise incisions.

Applications:

  • Refractive Surgery:

    • Development of advanced techniques such as ReLEx SMILE to correct myopia and astigmatism with a micro-incision of only 2mm.
    • Supports selective cornea transplants like DMEK, where only the thin Descemet’s membrane and the endothelium are replaced.

  • Cataract Surgery:

    • Improves precision in traditional procedures with:
      • More accurate incisions.
      • Reduced risk of infection.
      • Improved placement of intraocular lenses.
      • Enhanced predictability of astigmatism correction.
    • Especially beneficial for complex cases such as congenital, juvenile, or post-trauma cataracts.

Prior Examination:

  • Depends on the type of surgery being performed.

Associated Pathologies:

  • Cataracts.
  • Corneal opacity.
  • Keratoconus.
  • Myopia.
  • Astigmatism.
  • Hyperopia.
  • Presbyopia ("Old Eyes").
