Analysis of I-Trace High Order Aberrations Induced by Wavefront Optimized Ablation Profiles

Analysis of I-Trace High Order Aberrations Induced by Wavefront Optimized Ablation Profiles

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

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