    In this interview from the 2015 ASCRS Symposium, Dr. Karolinne Rocha discusses the iTrace and the HD Analyzer, new diagnostic technologies that identify and measure aberrations, helping surgeons make optimal choices to maximize vision outcomes for premium IOL patients.

    The iTrace integrates wavefront aberrometry with corneal topography, measuring both corneal and total aberrations to isolate internal aberrations of the eye. The device is particularly helpful when deciding between a refractive lens exchange and keratorefrative surgery in patients with dysfunctional lens syndrome.

    The HD Analyzer produces a dynamic aberration map using light scanning and double-pass retinal imaging. Dr. Rocha has used the device to identify patients with tear film instability and to quantify dry eye symptoms, allowing her to plan for treatment prior to surgery and set realistic surgical goals with patients.
