Title	Porous polyethylene orbital implant (Medpor®) after secondary enucleation
Abstract Nr.	P21

Purpose	To report the incidence of complications in patients who underwent implantation of a porous polyethylene (PP) sphere (MedporÒ) after secondary enucleation.
Methods	Prospective non randomized case series of 64 consecutive patients who underwent prior ocular surgeries before enucleation and implantation of a PP spherical implant.
Results	The mean age at the time of enucleation was 54 years (range, 1.4 to 80). 40 patients (62%) underwent one prior ocular surgery, 14 patients (22%) two prior surgeries and 10 patients (16%) more than two surgeries. Among the 64 PP implants, 18 (28%) were unwrapped, 33 (52%) wrapped with autologous sclera and 13 (20%) with homologous sclera. The prosthesis was fitted after a mean interval of 4.2 weeks (range, 4 to 10 weeks). After a mean follow-up of 40 months (range, 6 to 114 months) there was one case (2%) of conjunctival dehiscence, 3 cases (5%) of pyogenic granuloma and 8 cases (12%) of conjunctival inclusion cyst. All those complications were successfully treated. There was no case of orbital cellulitis, implant extrusion, and significant inflammatory response. No PP implant was drilled for peg placement or later removed. Superior sulcus syndrome was documented in 25 patients (39%) after a mean follow-up post enucleation of 4 months.
Conclusion	Anteriorly wrapped or unwrapped porous polyethylene orbital (MedporÒ) sphere appears to be well tolerated and with self-limited minor complications in patients who underwent prior ocular surgeries before enucleation.
