Lions World Vision Institute (LWVI) announced the expansion of its OptiGraft CAIRS (corneal allogenic intrastromal ring segments) service to now include asymmetrical laser-cut CAIRS. This enhancement broadens the therapeutic options for corneal surgeons managing advanced cases of keratoconus and other corneal ectatic disorders, LWVI said in a press release. 

OptiGraft CAIRS is an allogenic-based alternative to synthetic intrastromal ring segments, offering biocompatibility and precision-crafted donor tissue for corneal remodeling. With the development of asymmetrically laser-cut segments, surgeons can tailor ring sizes and geometries to match irregular corneal topographies and unique patient anatomy—enhancing surgical flexibility and precision in managing advanced keratoconus cases, the organization said. 

According to LWVI, the asymmetrical ring segments are created with the Ziemer Femto LDV Z8 femtosecond laser platform, which delivers fast, micron-level precision cuts. This latest enhancement, the organization said, provides greater off-the-shelf options to meet diverse surgical plans and patient needs. 

“Since creating the CAIRS technique in 2015, I’ve been honored by its global impact and proud to advance continued innovation through my work with Lions World Vision Institute,” said Soosan Jacob, MS, FRCS, DNB, pioneer of CAIRS and consultant to LWVI’s OptiGraft program.
