PURPOSE: To describe a new technique for harvesting freehand and horseshoe tectonic corneal grafts. METHODS: A retrospective, noncomparative interventional case series of 3 eyes from 2 patients was included. The area to be excised from the host was marked with a marking pen. Using the principle of the light table from architecture, the donor corneoscleral rim was placed over the marked area with an ophthalmic viscoelastic device in the interface to provide a coupling medium. The donor was then marked, tracing the exact shape of the tectonic graft with a 0.2-mm overlap ("copy"). This was harvested after mounting on an artificial anterior chamber and sutured in place with 10-0 nylon ("fix") to..
