Quantitative OCT-Based Longitudinal Evaluation of Intracorneal Ring Segment Implantation in Keratoconus, published in IOVS
Quantification tools in OCT were used to fully characterize anterior and posterior corneal topography as well as intracorneal ring segments pre- and post-operatively (7, 30 and 90 days) in keratoconic patients. ICRS produced flattening on the anterior corneal surface, although the benefit for corneal surface regularization varied across patients. The ICRS rotated by around 7 deg post-implantation. The study demonstrates that high speed OCT provided with quantitative tools is an excellent technique to evaluate ICRS surgery in keratoconus.
