As an advantage, the surgical treatment is performed in the peripheral cornea, not the central visual axis. In addition, as shown in the accompanying topography, it does not reverse the natural positive corneal asphericity. Another advantage is that Intacs are removable or exchangeable. The second topography shows the cornea after removal.
Refractive error returns to the original, as does the corneal topography.
With respect to time, this procedure will be as rapid to perform as current laser procedures. Patients experience rapid visual recovery and, therefore, little disturbance of their normal daily routines. With respect to cost, the Intacs are a completely different product.
