Corneal neovascularization, which is associated with complications in corneal diseases, can cause lipid deposit, decreasing vision, and graft rejection after penetrating keratoplasty (PKP). Corneal laser photocoagulation using an argon laser or yellow dye laser for ablation of corneal neovascularization has been described. We performed corneal argon laser photocoagulation (CALP) in two male patients with corneal neovascularization after herpetic keratitis. One PKP was performed after CALP and restored good vision with no rejection of the graft during an 8 month follow-up period. In the other case we observed visual improvement and no recurrence of corneal neovascularization after CALP.

Therapeutic keratoplasties for 7 patients (7 eyes) with the corneal perforation were performed at St. Mary's Hospital, Catholic University Medical College, from November 1988 to December 1991 for about 3 years. The causative diseases of corneal perforation were herpes simplex keratitis in 2 eyes (28.6%), corneal ulcers after trauma in 2 eyes (28.6%), and keratitis of unknown etiology in 3 eyes (42.9%). Postoperative complications were cataract (2 eyes; 28.6%), synechiaes(2 eyes; 28.6%), glaucoma (1 eye; 14.3%)' endophthalmitis (1 eye; 14.3%) and graft failure (1 eye; 14.3%). Among the 7 grafted corneas, clear corneas were noted in 2 eyes (28.6%), but opaque corneas developed in 4 eyes (57.1 %), and eVIsceration was performed in 1 eye (14.3%) due to endophthalmitis. After keratoplasty, the visual acuity was over 0.1 in lout of the 6 eyes. In the corneal perforation, it was good to delay keratoplasty until the intraocular inflammation was subsided, but we preferred to do the keratoplasty immediately for large perforation or removal of the causative disease.
