Severe caustic burns of the cornea in owl monkeys were treated with keratoplasty covered by a glued-on lens for splinting and preventing ulceration. The lens was removed five to six weeks after surgery when new vessels started to enter the graft. Four-millimeter transplants remained fairly transparent without ulceration in three out of four cases. Seven-millimeter transplants usually resulted in early detachment of the lens. The gluedon lens offered protection against ulceration and opacification during the healing process.
