What is eye removal surgery?
Eye removal surgery is a procedure performed to remove an eye that can no longer be saved and is causing ongoing medical problems such as pain, uncontrolled infection, or serious risk to overall health. Surgery is recommended only when all other treatment options have been exhausted and the eye no longer has the potential to see.
The two most common procedures used to remove an eye are enucleation and evisceration. While they differ in surgical technique, both procedures are performed to relieve pain, resolve infection or disease, and prepare the eye socket for a prosthetic eye. The external appearance of the socket following either procedure is essentially the same, and most patients are able to wear a custom prosthetic eye that closely matches their natural eye.
What is the difference between enucleation and evisceration?
Both procedures remove the eye, but they differ in how much of the eye's structure is removed.
Enucleation
Enucleation is the surgical removal of the entire eyeball, including the outer shell of the eye known as the sclera. The surrounding orbital tissues, eyelids, and eye muscles are left in place. Because the entire globe is removed, enucleation allows for pathologic examination of the eye under a microscope, which is important when a tumor is suspected. It is the preferred procedure for intraocular tumors, certain types of trauma, and cases where infection has spread beyond the inner eye.
Evisceration
Evisceration removes the inner contents of the eye while leaving the outer shell, the sclera, and the eye muscle attachments intact. Because the muscles remain connected to the sclera rather than being reattached to an implant, evisceration often results in better implant movement and, in turn, better movement of the prosthetic eye. It is a less invasive procedure and is appropriate for certain cases of painful blind eye and end-stage infection when a tumor has been ruled out.
Your surgeon will determine which procedure is appropriate based on the reason the eye needs to be removed, the condition of the eye and surrounding tissues, and your overall health.
Who needs eye removal surgery?
Eye removal surgery is recommended when an eye has lost all functional vision and is causing ongoing problems that cannot be managed with other treatments. Common reasons include:
- A painful blind eye that no longer responds to medication or other interventions
- Severe trauma that has left the eye beyond repair
- End-stage infection inside the eye, known as endophthalmia, that cannot be controlled
- An intraocular tumor, such as retinoblastoma or ocular melanoma, that requires removal of the eye
- End-stage eye disease, such as advanced glaucoma or diabetic eye disease, in which the eye is blind and causing chronic pain
- An eye that has become disfigured or collapsed and is no longer able to support a cosmetic shell
What should I expect during eye removal surgery?
Prior to surgery, you will meet with your oculofacial plastic surgeon for a comprehensive evaluation. During this appointment, your surgeon will:
- Review your medical history and the condition of the eye being removed
- Discuss whether enucleation or evisceration is the most appropriate procedure for your situation
- Examine the socket and surrounding structures
- Discuss the use of an orbital implant and what to expect from the prosthetic fitting process
Eye removal surgery is performed under general anesthesia and typically takes about an hour. Both enucleation and evisceration are outpatient procedures, meaning you go home the same day.
During enucleation, the entire eyeball is carefully removed and the six muscles that control eye movement are detached from the eye and reattached to an orbital implant placed inside the socket. The implant restores the volume of the socket and allows the muscles to remain active, supporting the movement of the prosthetic eye.
During evisceration, the inner contents of the eye are removed through a small incision in the sclera. Because the sclera and muscle attachments are left intact, an orbital implant is placed directly inside the scleral shell, where it is naturally supported by the surrounding tissue and muscles.
In both procedures, a temporary clear plastic shell called a conformer is placed over the implant after surgery. The conformer holds the shape of the socket and serves as a placeholder while the socket heals in preparation for a custom prosthetic eye.
What can I expect after eye removal surgery?
Most patients tolerate recovery from eye removal surgery well. You will be able to return to light daily activities within a week or two, with full healing taking six to eight weeks.
In the first several days following surgery, it is normal to experience:
- Swelling and bruising around the eye and eyelids
- Mild to moderate discomfort, which is managed with prescribed pain medication
- Discharge or crusting around the socket
- A pressure dressing over the socket for the first day or two
Antibiotic and anti-inflammatory drops or ointment are typically prescribed for one to three weeks following surgery. Follow-up appointments with your surgeon allow the healing process to be monitored and any concerns to be addressed promptly.
What are the risks of eye removal surgery?
Eye removal surgery is a well-established procedure. As with any surgical procedure, there are potential risks to be aware of:
- Bleeding or infection
- Poor wound healing
- Orbital implant exposure or migration
- Socket contraction over time
- Changes in eyelid position
Deciding to have an eye removed is one of the most difficult decisions a patient can face. The oculofacial plastic surgeons at The Iowa Clinic approach eye removal with the care and thoroughness that such a significant procedure deserves, guiding patients through every stage from the initial evaluation through prosthetic fitting and long-term socket care.
