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. Three months postoperatively, the graft was stable with no progression of the ectasia. The suturing of a corneoscleral graft over a severely ectatic cornea may be an acceptable technique for providing tectonic tissue support and stabilizing eyes with severe anterior segment ectasia.
