Purpose: To study the exposure rate of orbital implant post enucleation or evisceration procedures in two tertiary hospitals in Oman. Design: A retrospective, descriptive, cross sectional study. Materials & Methods: Patients’ records were reviewed for patients’ demographics, surgical indications, implant types, follow ups and any reported complications after surgeries. Patients with a minimum of one year follow up period were selected. All patients who underwent enucleation or evisceration with primary orbital implant were included in the study. Patients who underwent secondary orbital implant were excluded from the study. Enucleation that involves the removal of unhealthy globe with a part of the optic tract is also performed for patients with severe eye trauma, panophthalmitis, painful blind eye, and patients with inherent anomalies, for instance, microphthalmia. whereas evisceration that involves the removal of the contents of the world, going the sclerotic coat, extraocular muscles, and optic tract intact is mostly thought of for patients with endophthalmitis or perforated tissue layer lesion. The orbital implant, used when surgical procedure and evisceration surgeries, has many distinctive blessings. These blessings area unit to interchange lost orbital volume, to take care of the structure of the orbit, and to help motility to the superimposed ocular prosthetic device. There area unit 2 main classes of implants classified per the fabric from that they’re factory-made inert material (glass, silicone, alkyl methacrylate) and bio-integrated material .The inert implant characterised by providing comfort, cost-effectiveness, and lower rate of extrusion. Its disadvantages area unit weakened motility and risk of implant migration.
