About

This work aims at the analysis of ocular aberrations induced by wave front optimized ablation profiles WFO using I-Trace aberrometer (Ray -Tracing)

Full description

The iTrace (Tracey Technologies, Houston, Tx) is uniquely designed to combine Placido corneal topography with a ray tracing aberrometer to measure quality of vision in a patient.
