A new surgical technique for anterior segment ectasia: tectonic lamellar sclerokeratoplasty.

A 41-year-old patient with severe anterior segment ectasia and a previous history of failed corneal graft was treated by placing a 14-mm tectonic corneoscleral allograft in the eye to support both the corneal and the scleral thinning. Nylon 10-0 interrupted sutures were used at the sclero-scleral junction. The host conjunctiva, including the limbal area, was carefully sutured to the donor limbal area.
