Bottom Line

Encelto is a surgically placed cell-based eye implant for adults with idiopathic macular telangiectasia type 2. It is meant to slow retina cell loss, not quickly sharpen vision.

Encelto (revakinagene taroretcel-lwey) is an allogeneic encapsulated cell-based gene therapy implant. The label lists it for adults with idiopathic macular telangiectasia type 2 1.

The implant contains retinal pigment epithelial cells that make recombinant human ciliary neurotrophic factor. This factor is released into the eye to support retinal cells.

In phase 3 trials, cell-based ciliary neurotrophic factor therapy slowed ellipsoid zone area loss in macular telangiectasia type 2 2.

How Encelto Works

Encelto is a tiny capsule with living donor cells inside. The cells are engineered to release recombinant human ciliary neurotrophic factor into the eye 1.

The capsule lets nutrients in and lets the factor out. It also keeps the cells separated from the immune system.

The goal is to slow retinal degeneration in macular telangiectasia type 2, especially photoreceptor loss 2.

Risks and Side Effects

Encelto is an eye surgery and implant treatment, so risks are different from office injections.

  • Severe vision loss.
  • Eye infection.
  • Retinal tear or detachment.
  • Vitreous bleeding.
  • Implant extrusion or wound problems.
  • Cataract progression.
  • Delayed dark adaptation.
Same-day warning: Call the surgeon for pain, discharge, worsening redness, floaters, or vision drop after surgery.

Cost and Insurance

Encelto is usually billed under medical insurance. Costs can include the implant, operating room, surgeon, anesthesia, imaging, and follow-up visits.

  • Prior authorization is expected.
  • Coverage may require confirmed idiopathic macular telangiectasia type 2.
  • Plans may ask for imaging that shows eligible retinal changes.
  • Out-of-pocket cost depends on deductible, copay, coinsurance, and assistance programs.

Ask the retina office for a written estimate and coverage review before surgery.

Common Questions About Encelto

No. Encelto is for adults with idiopathic macular telangiectasia type 2, which is a different macular disease.

Next Steps

  1. 1Bring macular telangiectasia type 2 records and scans to your Encelto consultation.
  2. 2Ask whether your imaging shows retina cell loss that Encelto is meant to slow.
  3. 3Review surgery risks, healing drops, and emergency warning signs.
  4. 4Confirm insurance authorization and expected out-of-pocket cost before surgery.
  5. 5Call the surgeon right away for pain, discharge, worsening redness, new floaters, or vision drop.
