“…In the human literature, reported complications include implant displacement (20%), sulcus deformity (12%–18%), implant extrusion (0.6%–10.6%), eyelid laxity (5.3%), conjunctival granuloma (5.3%), hemorrhage (10%), cellulitis (0.6%), infection (0.56%–0.7%), cyst formation (1.3%–1.6%), dehiscence (2.6%–2.9%), conjunctival contracture (5.4%), and ptosis (20.9%) 8–22 . In comparison, the authors of the present study found higher rates of cellulitis, infection, implant migration, and implant extrusion.…”

Objective To describe clinical and histopathologic pre‐operative diagnoses as well as associated post‐operative complications following orbital silicone implantation in dogs undergoing enucleation and evaluate owner satisfaction. Animals studied One hundred and eighty‐six dogs who underwent enucleation with orbital implant. Procedures Medical records from dogs that underwent enucleation with orbital implant performed at Virginia‐Maryland Veterinary Teaching Hospital between 2007 and 2019 were reviewed. Owners were surveyed via telephone regarding client satisfaction. Results Enucleation followed by orbital implant placement occurred in 215 eyes of 186 dogs. The most common pre‐operative diagnoses were glaucoma (68.8%), uveitis (17.7%), cataracts (15.8%), intraocular neoplasia (13.0%), and lens luxation (10.7%). The most common histopathologic diagnoses were retinal degeneration (46.5%), uveitis (39.5%), cataract (29.8%), retinal detachment (27.4%), and secondary glaucoma (26.5%). Fourteen eyes (6.5%) from ten dogs had post‐operative complications reported including orbit cellulitis (n = 11), implant migration (n = 1), and implant extrusion (n = 1). Five of these dogs (50%) had concurrent diabetes mellitus. Median complication time from surgery was 41 days (range: 11–541 days). Ninety‐five owner survey responses were completed with a median time of 6.3 years following surgery. Most owners, 85.3% (n = 81), were satisfied with the post‐operative outcome. Conclusion Enucleation with implantation of an orbital implant is a viable and safe method for irreversibly blind eyes. Diabetes mellitus may be a risk factor for the development of post‐operative complications. Intraocular neoplasia was not associated with development of post‐operative complications. Results of this study indicated high owner satisfaction rates for improving cosmetic appearance after enucleation in dogs.

“…1. Метод оперативного вмешательства: энуклеация; эвисцерация с резекцией роговицы, Для уменьшения риска послеоперационных осложнений, особенно при энуклеации, важно выбрать оптимальный материал имплантата [8]. У 121 пациента (91,7 %) был использован орбитальный вкладыш из пористого ПТФЭ, характеризующийся биосовместимостью, легкостью стерилизации, возможностью ручной обработки, низким риском инфицирования, миграции и экструзии, приемлемой стоимостью [9][10][11].…”

Aim. To determine the optimal shape of the locomotor stump and the configuration of the corresponding ocular prosthesis, ensuring their maximum motility in patients with anophthalmia with different methods of eye removal. Materials and methods. The study group consisted of 132 patients aged 1880 years after enucleation or evisceration. Examination methods included medical history; examination of eyelids, measurement of length and width of the palpebral fissure, as well as of the depth of conjunctival fornices on both sides; assessment of the volume, shape, surface topography, position and excursions of the locomotor stump, of the protrusion of the ocular prosthesis compared to the contralateral eye; photo registration of the studied parameters. Results. During the study, there were 3 types of locomotor stump identified: moderate with retraction in the upper third; voluminous flattened; voluminous hemispherical. The locomotor stump after enucleation was voluminous flattened or moderate with retraction in the upper third. The best motility of the locomotor stump was noted nasally and downward. The motility of the ocular prosthesis was 47.4% compared to the contralateral eye. The locomotor stump after evisceration with keratectomy was voluminous hemispherical or voluminous flattened. Its motility in all four directions was about the same. The motility of the ocular prosthesis in comparison to the contralateral eye was 55.9%. The locomotor stump after evisceration without keratectomy was voluminous hemispherical, uniform, smooth. The motility of the locomotor stump was maximal in comparison to other groups and relatively equal in all four directions. The motility of the ocular prosthesis in comparison to the contralateral eye was 68.2%. Conclusion. The optimal shape of the locomotor stump, providing the greatest motility of the ocular prosthesis is voluminous hemispherical. The same protrusion of the eyeball and that of the cosmetic prosthesis relatively to the frontal plane after enucleation is achieved by increasing the thickness of the prosthesis itself, which reduces its motility. Evisceration with implantation of the orbital prosthesis involves the use of a thin-walled ocular prosthesis, the back surface of which ideally repeats the locomotor stump surface and does not prevent its maximum motility. When removing a squinting eyeball with preserved corneal diameter, a smaller implant should be used to prevent excessive opening of the palpebral fissure, or to prefer evisceration with keratectomy.

“…Jongman et al 18 (level III) reviewed 179 patients (mean age, 60.9 years) for an average of 12.6 months after enucleation with placement of a sclera-wrapped acrylic implant. Three patients experienced complications: 1 demonstrated implant exposure, 1 demonstrated orbital cellulitis, and 1 experienced intractable chemosis (0.6% for each complication).…”
