“…The state and motility of the ocular prosthesis are essential in cosmetic ocular prosthetics [14,19]. We have previously reported on developing a model of ocular prosthesis designed to be permanently fixed to the anterior surface of the MS with the aim to improve the cosmetic effect in ocular prosthetics in patients that underwent evisceration, improve prosthesis motility and prevent low lid ectropion resulting from prosthesis-induced pressure in the lower lid fornix [10].…”

Background:The state and motility of a cosmetic ocular prosthesis are important. Purpose: To develop a novel technique of evisceration or enucleation secondary to trauma, chronic uveitis or uveal melanoma, with permanent and removable fixation of the ocular prosthesis in a musculoskeletal stump (MS). Material and Methods: Group 1 comprised 52 patients with chronic uveitis secondary to trauma and phthisis bulbi who underwent evisceration. After evisceration, a polymer composite implant or a polytetrafluoroethylene (PTFE) implant was used to shape an MS with a hole in it for the pegged prosthesis, and the prosthesis motility in these patients was compared with that in the 13 controls in whom an MS without a hole in it for the pegged prosthesis was shaped. Group 2 comprised 31 patients with uveal melanoma who underwent enucleation with a PTFE implant used to shape an MS with a hole in it. The prosthesis motility in these patients was measured and compared with that in the 100 controls in whom an MS without a hole in it for the pegged prosthesis was shaped. Results: In patients of group 1, total prosthesis motility at 3 and 12 months improved to 132.50 ± 6.40 and 147.30 ± 6.70, respectively, versus 103.70 ± 18.30 and 103.10 ± 6.00, respectively, in the controls. No implant exposure was observed over the follow-up period. In three patients of group 2, diastasis of the conjunctival margins with implant exposure was observed at the margin of the hole at months 3 and 7, which necessitated implant removal. In patients of group 2, total prosthesis motility in the four meridians at 3 and 12 months was 141.

“…The conjunctiva is incised along the limbus and dissected to the posterior pole of the globe, and the outer rectus muscles are sutured to the sclera and cut away from it. High-frequency electric current is used to dissect the optic nerve and the vascular plexus (ophthalmic artery and superior ophthalmic vein) [19].…”
