Long-term Results of Hydroxyapatite and Medpor(R) Orbital Implant

ABSTRACT

PURPOSE: This study was conducted to determine long-term results of Hydroxyapatite and Medpor(R) ocular implants. METHODS: This study was done on 108 eyes inserted with hydroxyapatite ocular implant and 82 eyes inserted with Medpor(R) ocular implant that were treated at the present hospital from January 1992 to December 2002. We compared the types, frequencies, and onset and treatment of complications according to the types of surgery. RESULTS: The clinical outcome for 14 months to 10 years (average 57.6 months) was examined in the hydroxyapatite implantation group. The complications were implant exposure in 14 eyes (13%), soft tissue complication in 27 (25%), eyelid complication in 30 (27.8%), and complication due to Peg insertion in 21 (27.3%). The clinical outcome for 5 months to 4 years (average 18.6 months) was examined in the Medpor(R) implant group. The complications involved were implant exposure in 5 eyes (6.1%), soft tissue complication in 14 (17.1%), eyelid complication in 25 (30.5%), and complication due to MCP insertion in 3 (16.7%). CONCLUSIONS: Active treatment for early complications and long-term follow-up for late complications are needed with hydroxyapatite and Medpor(R) implantations.
