Abstract
Purpose:
We describe a technique to avoid decentration of the visual axis of the Boston type 1 keratoprosthesis (Kpro), performing 2 concentric trephinations with femtosecond laser.
Methods:
Two concentric side cuts were performed in a donor cornea using the 150-kHz Intralase™ FS laser. Within the same applanation procedure, an 8.5-mm-diameter anterior side cut was performed, followed by a concentric 3-mm-diameter anterior side cut.
Results:
The technique was successfully replicated in 7 cases.
Conclusions:
Femtosecond laser-assisted double trephination results in a correctly prepared donor cornea, and in an inner side precisely matched with the prosthesis. At the end of the surgery, the Kpro was correctly centered.
