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.
