Stability of the Laser

  • Excimer Laser is a gas based laser. Even after many improvements, it is not as stable as a fiber based femtosecond laser
  • MEL 80 Excimer laser requires about six interventions in the year (including gas bottle changes)
  • VisuMax Femtosecond Laser requires lesser interventions (Routine Check ups)

Corneal Reshaping without ablation (Ablation VS Cutting)

  • An excimer laser performs photoablation
  • The photoablation rate increases linearly with fluence beyond a certain threshold
  • Excimer Laser fluence and photoablation rate gets influenced by various factors –corneal hydration levels, humidity levels, the presence of organic vapors, the depth of ablation
  • This results in a scatter affecting visual outcomes, especially for the treatment of high myopia.
  • Regression may happens in high Myopia.

SMILE ®

  • Uses cutting instead of ablation
  • A binary process instead of linear
  • Much less influence of any external factors
  • Reflected in the tremendous accuracy achieved.
  • Results are especially interesting for high myopia, a group in which excimer lasers don’t fare as well.
  • Lesser incidents of Regression in SMILE
