    Dr. Soosan Jacob demonstrates her novel technique for creation of corneal allogenic intrastromal ring segments (CAIRS) for treatment of keratoconus and other ectatic disorders. The segments are created from a donor corneoscleral rim that has been de-endothelialized and de-epithelialized, then cut to shape with a double-bladed trephine. Following a riboflavin soaking, the tissue is threaded onto an Intacs segment and guided through a femtosecond laser-dissected channel in the patient’s cornea. After the CAIRS are in place, the procedure is finished with epi-off crosslinking. Dr. Jacob’s technique has shown good refractive and topographic outcomes, and is also biocompatible, reversible and adjustable. The allogenic segments may also be implanted at a more superficial depth than synthetic intrastromal corneal ring segments (ICRS).

    Dr. Jacob discusses her technique and visual outcomes in this interview from AAO 2017
