Surgical outcomes of unwrapped acrylic orbital implants: A review of 192 patients

Purpose. - The purpose of this study is to report the results in a series of acrylic orbital implant placements without the use of wrapping material.Methods. - We retrospectively reviewed the records of the patients who underwent enucle-ation with acrylic orbital implant insertion without scleral wrapping at the Department of Ophthalmology, Poznan ' University of Medical Sciences, Poland, between 2013 and 2020.Results. - There were 192 patients: 102 women and 90 men, mean age: 60 years (range: 13-90 years). In the majority of cases, the reason for enucleation was uveal melanoma (148 patients-77.1%), followed by secondary glaucoma in 22 patients (11.5%) and painful, phthisical eye in 16 (8.3%). The median follow-up was 23 months (range: 1-96 months). The stability of the implants was satisfactory in the majority of cases, and there were no cases of implant migration identified during the study period. We noted a total of 4 (2%) implant exposures. Other postoperative complaints included eyelid malposition--21 patients (11%), Tenon's capsule thinning (15 patients-7.8%) and post-enucleation eye socket syndrome (PEES)--7 patients (3.6%). The rate of postoperative complications was associated only with a history of previous ocular surgery (P = 0.006).
