Indications, complications and prognosis for repeat penetrating keratoplasty.

A review of 47 repeat penetrating keratoplasties in 29 eyes showed the most frequent indications to be Fuchs' dystrophy, bullous keratopathy, and keratoconus. The most common postoperative complications were edema, glaucoma, and vascularization. Ninety other surgical procedures were performed in 26 of the 29 eyes. Final vision was no worse than 20/300 in 26% of the group. It is suggested that repeat grafting should be continued in the absence of contraindications.
