Understanding Eye Removal Surgery (Enucleation): Causes & Procedure

Enucleation is the surgical removal of the entire eyeball, performed when an eye is severely damaged, diseased, or painful and cannot be saved. The procedure preserves the eye muscles and orbital contents to allow for movement of a future prosthesis.

Common Indications

• Severe ocular trauma (rupture, perforation) with no visual potential.
• Advanced, painful glaucoma unresponsive to treatment.
• Intraocular tumors (e.g., retinoblastoma in children, uveal melanoma in adults).
• Severe uveitis or endophthalmitis with irreversible damage.
• Uncontrolled ocular pain in a blind eye.
• Cosmetically unacceptable blind eye (phthisis bulbi).

Surgical Procedure

1. Performed under general anesthesia.
2. Eye muscles (recti and obliques) are detached from the globe.
3. Optic nerve is cut; eyeball removed intact.
4. An orbital implant (silicone sphere, hydroxyapatite, or porous polyethylene) is placed in the socket to maintain volume.
5. Eye muscles are attached to the implant (or a wrapping material) to transmit movement.
6. Conjunctiva closed over the implant.
7. A temporary clear plastic conformer (shell) is placed behind the eyelids.

Recovery & Aftercare

• Hospital stay: typically 1–2 days.
• Eye patch/shield worn for several days to weeks.
• Antibiotic and steroid drops/ointment prescribed.
• Pain, swelling, bruising subside over 2–4 weeks.
• Orbital implant integrates over months (vascularization for porous implants).
• Custom ocular prosthesis (artificial eye) fitted 6–8 weeks post-op by an ocularist. The prosthesis is painted to match the fellow eye.

Risks & Complications

• Bleeding, infection, implant exposure/extrusion.
• Implant migration, socket contracture (requiring reconstruction).
• Sympathetic ophthalmia (rare autoimmune reaction in fellow eye).
• Anesthesia risks.

Alternatives

• Evisceration: Removes intraocular contents but preserves the scleral shell; faster recovery, better motility. Not suitable for intraocular tumors.
• Scleral buckling/vitrectomy: For retinal detachment, not eye removal.

The choice depends on diagnosis, patient health, and goals. A multidisciplinary team (ophthalmologist, ocularist, sometimes oncologist) guides decision-making. Cosmetic outcomes with modern implants and prostheses are excellent.
