KPro retention failure rate influenced by surgical indication

CHICAGO — Patients whose indication for implantation of a Boston Type 1 keratoprosthesis was Stevens Johnson syndrome had a higher retention failure rate than other patients implanted with the device for other reasons, according to study results presented here.
At Cornea Subspecialty Day preceding the American Academy of Ophthalmology meeting, Anthony J. Aldave, MD, reported his experience with the device in a retrospective, single surgeon consecutive case series.

Long-term outcomes of patients who had received the device between May 2004 and May 2011 were reviewed, and data included 120 procedures in 97 eyes of 93 patients.
Whereas approximately 6% of patients had vision of 20/200 or better before surgery, 60% of patients followed up at 5 years achieved 20/200 or better vision, Aldave said.
“Three-quarters of eyes [had] a final visual acuity that was within three lines of their best ever visual acuity,” Aldave said.
Regarding retention, approximately one-third of KPros implanted in the 120 procedures had to be removed; however, at the final visit, the KPro was in place in 84% of the 97 eyes.
“Failed corneal transplant, if that’s the indication for KPro, the retention failure rate is significantly lower when compared to all other indications for KPro implantation. In contrast, Stevens-Johnson syndrome is associated with a significantly higher retention failure rate compared to all other indications,” Aldave said. – by Patricia Nale, ELS
