Range of motion in ocular implants following enucleation: hydroxyapatite vs porous polyethylene [medpor]

ABSTRACT

To compare the range of motion of hydroxyapatite [HA] and porous polyethylene [Medpor] ocular implants in enucleated eyes. This comparative study was performed on records of 34 patients who underwent unilateral enucleation and implantation of hydroxyapatite [13 cases] or Medpor [21 cases]. The two groups were compared regarding age, gender, cause of enucleation, laterality, and movement. Patients were male in 55.9%. Mean age of patients was 29.7 year [1-61 years]. The most common cause of enucleation was trauma [55.9%] and the most common complication was mucopurulent discharge [14.7%]. There was no case of extrusion, migration or exposure. Moderate to good motility was achieved in 89.3% of patients in the Medpor group and 86.6% in the HA group. There was no statistically difference between the two group regarding upward movement [P=0.68], downward movement [P=0.62], adduction [P=0.17] and abduction [P=0.65]. Medpor and hydroxyapatite ocular implants are comparable regarding range of motion
