Abstract | INTRODUCTION: To report the results of post-traumatic enophthalmos/hypophthalmos correction with high-density porous polyethylene wedge implants in seeing eyes. METHODS: This is an interventional case series of 25 patients (25 eyes) with post-traumatic enophthalmos and hypophthalmos, who underwent orbital reconstruction to correct the enophthalmos and hypophthalmos using Medpor® wedge implant. The aim was an overcorrection of 1 mm in comparison to the other eye, intra-operatively. If needed, trimming of the wedge implant or adding Medpor® sheets were used to achieve the goal. Success was defined as achieving the globe position within 1 mm of the other eye in the last follow-up. Improvement and failure were considered as correction outside the success range of 1 mm and no change in the amount of enophthalmos/hypophthalmos, respectively. RESULTS: Patients were followed for at least 6 months (mean= 12.66, SD= 12.32). Success, improvement and failure of enophthalmos correction were: 58.3% (14/24), 37.5% (9/24) and 1 (1/24, 4.1%), respectively. Success, improvement and failure of hypophthalmos correction were 73.68% (14/19), 15.78% (3/19) and 5.26% (1/19), respectively. There was no significant difference between the success rate of enophthalmos versus hypophthalmos correction (P= 0.8). Results of 1-month follow up change in enophthalmos and hypophthalmos significantly correlated (r= 0.92, P= 0.000) with the change recorded at last follow up. CONCLUSIONS: Porous polyethylene wedge implants are useful and safe in correction of enophthalmos and hypoglobus in seeing eyes. Appropriately positioned implant yields no significant difference in correction of enophthalmos versus hypophthalmos.
