Ocular Conformer After Enucleation Surgery — First 60 Days Guide

The short version: An ocular conformer is a temporary clear or opaque plastic shell placed in the socket after enucleation, evisceration, or ocular surgery. It maintains the socket shape and eyelid contour while healing progresses, typically for 6-12 weeks, before you transition to a custom prosthetic eye. Conformers are billed under HCPCS V2628.

What is an ocular conformer?

An ocular conformer is a curved plastic (acrylic or silicone) shell shaped to fit the eye socket. It has no iris, no color — it's typically clear or opaque. Its job is not cosmetic; it's structural. During the 6-12 weeks after enucleation or evisceration surgery, the socket tissue is healing and remodeling. Without a conformer, the eyelids can adhere to each other, the socket can shrink, and the fornices (upper and lower cul-de-sacs) can collapse.

The conformer prevents all of that by holding the socket in the shape and volume that a custom prosthesis will eventually occupy.

Typical timeline after enucleation surgery

Week 0 (surgery day): Ocular surgeon places a temporary conformer during surgery. Pressure patch and antibiotic ointment applied. Discharge home with follow-up in 1 week.
Week 1-2: First post-op visit. Surgeon may swap the initial conformer for a smaller/larger size based on healing. Ointment continues. Eyelids may still be swollen.
Week 4-6: Swelling has resolved. Socket has begun to establish its permanent shape. Conformer may be resized. Referral to an ocularist typically happens here.
Week 6-8: Initial ocularist visit. Ocularist takes a socket impression using alginate material. The custom prosthesis is fabricated in the lab.
Week 8-12: Custom prosthesis fitting appointment. The conformer is removed and the finished prosthesis inserted. Instructions on care and insertion/removal given.

Types of conformers

Type Material Use Typical duration
Clear surgical conformer Acrylic (PMMA) Immediately post-op, allows physician to visualize healing Days 0-14
Opaque conformer Acrylic or silicone Ongoing socket maintenance Weeks 2-12
Custom-molded conformer Individually shaped acrylic Complex sockets, prior implant migration Weeks 4-12 or long-term

How to care for a conformer

  1. Do not remove without provider approval. During the first 4-6 weeks, the socket is still healing. Removing the conformer prematurely can allow adhesions to form.
  2. Continue prescribed antibiotic ointment as directed. Typical schedule: 3-4 times daily for the first 1-2 weeks, then tapered.
  3. Clean the eyelid area gently with warm water and a soft cloth. Do not scrub. Do not use soap on the socket.
  4. Wear an eye shield at night for the first week to prevent accidental pressure on the socket.
  5. Watch for signs of infection: increasing pain, thick purulent discharge, spreading redness, fever. These warrant same-day evaluation.

What if the conformer comes out?

Conformers can occasionally dislodge, especially in the first week or during heavy sneezing. If yours comes out:

  1. Do not panic. Rinse the conformer with saline or clean water.
  2. Contact your ocular surgeon or an ophthalmology urgent care within 24 hours.
  3. In the meantime, keep the eye area clean and wear an eye shield if you have one.
  4. Do NOT attempt to reinsert without provider guidance in the first 2 weeks post-op.

Insurance coverage — HCPCS V2628

Conformers are billed under HCPCS code V2628 (Fabrication and fitting of ocular conformer). Medicare Part B typically covers this as part of post-enucleation care. Private insurance usually follows. Coverage details:

  • Coverage generally requires an ophthalmologist prescription and enucleation/evisceration surgical history
  • Reimbursement rate: ~$150-300 depending on Medicare Administrative Contractor region
  • You may pay 20% coinsurance + Part B deductible
  • See our V2623 insurance guide for related billing codes

Transitioning from conformer to custom prosthesis

At 6-8 weeks post-op (or when your surgeon clears you), you'll be referred to an ocularist. The transition process:

  1. Ocularist evaluates socket depth, contour, and any residual healing needs
  2. Alginate impression of the socket taken
  3. Wax pattern fabricated and fit-tested
  4. Iris painted to match your other eye (color, pattern, striations)
  5. Sclera colored to match
  6. Blood vessels painted
  7. Prosthesis polished and delivered (typically 2-4 weeks after impression)

See our insertion guide for what happens after you receive your custom prosthesis.

When you might keep the conformer longer

  • Socket infection delaying prosthesis fitting
  • Radiation therapy affecting healing
  • Complex reconstruction (implant migration, socket contracture)
  • Pediatric patients where growth requires ongoing conformer size changes before final prosthesis

Frequently asked questions

How long do I wear an ocular conformer?

Typically 6-12 weeks after enucleation or evisceration. Some patients keep it longer if healing is delayed or if custom prosthesis fitting must be postponed.

Does the conformer look like an eye?

No. Conformers are typically clear or opaque, without any iris color. They are structural, not cosmetic. You can wear an eye patch over the conformer if you prefer during the healing period.

Is a conformer covered by insurance?

Usually yes, under HCPCS V2628. Medicare Part B and most private insurers cover it as part of post-enucleation care.

Can I sleep with the conformer in?

Yes. You should keep it in continuously during the healing period unless your surgeon instructs otherwise. Wear an eye shield at night for the first week.

Where do I get a conformer if mine comes out?

Contact your ocular surgeon first. If you need a replacement conformer between visits, SciMed carries ocular conformers at $75 with same-day US shipping. Only use as a temporary measure until your surgeon can evaluate.
