Corneal allogenic intrastromal ring segments (CAIRS) are semicircular pieces of donor corneal stroma, which may be surgically implanted to flatten keratoconic corneas. These segments can be trimmed to different thicknesses; whereas thicker segments confer greater flattening, their bulk renders them more technically challenging to insert. Consequently, thinner segments are often preferred, especially for starting surgeons. Here, we describe a technique for transiently thinning CAIRS to facilitate easy insertion, thereby permitting the use of thicker segments to achieve the maximal flattening effect.
