Santhiago PTA Report

Simulate the impact of your LASIK surgery

  • Input fields for flap thickness and ablation depth
  • Comprehensive visualization with an index and graph
  • Percentage tissue altered map simulating the residual corneal thickness

The Santhiago PTA Report TM is a simulation tool to predict the probability of creating an ectasia after LASIK or PRK surgery in eyes with normal preoperative topography. By taking into account preoperative corneal thickness, ablation depth and flap thickness, the PTA index shows whether or not your patient is a suitable candidate for LASIK or PRK.

The PTA+ index adds additional safety through taking into account the relative contribution of flap thickness and ablation depth in specific borderline cases.

Good and comprehensive tool that can be used for patient education and decision making.
