• Thirty-four eyes with advanced aphakic bullous keratopathy were treated with the Cardona keratoprosthesis as a primary procedure. There were three extrusions (9%), two of which were associated with infections; two other conditions were worsened (6%) as a result of a late permanent vitreous hemorrhage or possibly an infection. Twenty-eight eyes (82%) showed a notable improvement during follow-up periods that ranged from 6 to 72 months. The advantages and limitations of this technique are compared to those of penetrating keratoplasty.
