Abstract
A pilot study was carried out in Pakistan to assess the feasibility of the use of lathed freeze-dried corneal tissue in the treatment of corneal scarring. Six eyes underwent lamellar keratoplasty and were followed up for 18 months. Visual improvement was obtained in every eye. In one eye, the procedure was complicated by delayed epithelialization of the graft, but in the remaining five patients, the grafts epithelialized rapidly. The use of freeze-dried donor tissue simplifies storage and distribution of corneas and may offer the best hope of treatment in developing countries for patients with corneal scarring.
