Longitudinal Corneal (OCT-based) and Total aberrations in Intracorneal Implant treatment of keratoconus, published in AJO
The study explores the longitudinal changes in optical quality in keratoconic eyes implanted with intrastromal ring segments (ICRS).
Corneal aberrations were obtained, for the first time, from OCT. Ocular aberrations were measured with Laser Ray Tracing. ICRS produced a decrease in astigmatism, but on average did not produce a consistent decrease of HOAs.
