Eye Eneucleation with implant

The procedure may be performed under general or local anesthesia, according to the surgeon's preference. In either case, the injection is given in the retrobulbar space. An antibiotic (eg, cefazolin) and an anti-inflammatory (eg, dexamethasone) are also given intravenously. Technique: A lid speculum is placed,using a toothed forceps, the conjunctiva is tented up close to the limbus, then scissors are used to cut the conjunctiva. A 360° peritomy is then performed, with care taken to preserve as much of the conjunctiva and Tenon's capsule as possible. The extraocular muscles are then tagged with 5-0 Vicryl sutures and are released by resection at their attachments to the globe. A neurectomy is then performed, according to the surgeon's preference, and the globe is delivered. Care should be taken to maintain hemostasis until the implant is placed in the orbit. Proper sizing of the orbit is essential to avoid complications, an undersized implant may result in enophthalmos or a deep superior sulcus, conversely, an oversized implant increases the risks of wound dehiscence, exposure, and infection, and may complicate the coupling of the artificial eye to the motility peg. The wound should be closed with separate closures of Tenon's capsule and the conjunctiva. Anterior Tenon's capsule is closed with interrupted 5-0 Vicryl sutures; the conjunctiva is closed with a running 5-0 Vicryl suture. Antibiotic ointment is applied to the socket and an acrylic conformer is placed over the ...
