Key Points

Examine the technical capabilities and donor tissue management challenges associated with femtosecond laser-assisted corneal allogenic intrastromal ring segment implantation for keratoconus.
Reviewed technical applications of femtosecond lasers in fashioning corneal allogenic intrastromal ring segments (CAIRS).
Analyzed clinical utility and ethical considerations concerning the stewardship and supply of human donor corneal tissue.
Femtosecond laser-sculpted allogenic intrastromal segments provide a biocompatible alternative to synthetic inserts for corneal remodeling in keratoconus.
Broader clinical adoption requires optimized donor tissue stewardship to mitigate pressures on donor cornea supplies in eye banks.
