Abstract
Purpose:
To study anatomical status of eyes that had Boston Keratoprosthesis (KPro) transplantation using anterior segment optical coherence tomography (AS-OCT).
Methods:
This prospective study was conducted on 8 pseudophakic eyes and 2 aphakic eyes that had KPro transplantation. We evaluated anatomical relationship between KPro and corneal grafts, fibrous membrane formation, and depth of the anterior chamber using AS-OCT.
Results:
There was no space neither between front parts of KPro and corneal grafts nor between grafts and back plates in all eyes. Fibrous membrane formation was observed in back plate holes in three eyes and on the back surface of KPro in one eye. Mean anterior chamber depth was 3.17 mm before surgery (range; 2.27 to 3.95mm). After KPro transplantation, the stem of KPro extended beyond papillary plane in eight eyes. There was no correlation between the preoperative anterior chamber depth and the postoperative anatomical status of the stems.
Conclusions:
AS-OCT is useful to assess fibrous membrane formation and anatomical status of eyes undergone KPro transplantation. The stem of KPro seems to be too long for Asian eyes.
