SUBSTANTIAL loss of corneal tissue following penetrating trauma is best treated by immediate closure of the defect with donor corneal material. Although such injuries are uncommon, they constitute emergencies which generally necessitate the use of preserved corneal tissue.1-3 Customarily, the surgeon cuts the graft free-hand to the size of the defect and then transfers it to the recipient and sutures it in place. Alternatively, he may attempt trephination of a circular area around the corneal defect,3-5 but with an open globe, this is difficult and hazardous at best. In either case, unless the graft closes the defect tightly, reformation of the anterior chamber and the ultimate survival of the eye are compromised.
The present paper describes a simple technique for fitting the donor cornea to the recipient defect in situ; it assures a reliable closure without the need for technically difficult measurements or estimates.
