Complications of Hydroxyapatite and Medpor Ocular Implants Following Enucleation

To compare complications and motility of hydroxyapatite versus medpor ocular implants after enucleation at Ahvaz Imam Hospital (from Jan 2010 to Jun 2011). In a clinical trial, 50 patients scheduled for enucleation were randomly divided in two groups of 25 patients. Group 1 underwent enucleation + hydroxyapatite (HA) and group 2 underwent enucleation +medor implant. All patients were operated by 2 surgeons. Then patients were visited 10, 30, 90 and 180 days after surgery for complication and motility. Patient age ranged from 8 to 68 years with a mean of 36.3 years, 52% of the patients were male and 48% were female. The most common used implant was 18 by size, the most common cause of loss of vision was trauma and the most common cause of surgery was cosmetic reasons in both groups. Complications in both groups were similar and the rate was high in both group in the early postoperative days. The most common complication was mucopurulent discharge, in the first month was 36% that reduced to 8% in the end of study. Mean amount of ocular motility was more in abduction: 4.72 mm and 4.58 mm in HA and medpor groups respectively but it was less in upgaze; 3.18 in HA and 3.14 in medpor groups. Complications and motility were similar in two groups and there was no significant difference (P= 0.99). According to our study, the rate of complications and motility are similar in HA and Medpor ocular implant after enucleation.
