Evaluation of a double-setting alpha-tricalcium phosphate cement in eviscerated rabbit eyes.

Purpose: To evaluate the macroscopy, microstructure, and tissue reaction of a double-setting alpha-tricalcium phosphate bone cement used as an intraocular implant in rabbits.

Methods: The internal and external surface of the double-setting alpha-tricalcium phosphate implant was analyzed macroscopically and by scanning electron microscopy. Twelve New Zealand rabbits received 12-mm implants made of double-setting alpha-tricalcium phosphate cement after unilateral evisceration.
