Improving Vision in Cases of PMD

- Where Advanced Technology Meets Compassionate Care

Pellucid marginal degeneration (PMD), often called pellucid, is a rare and progressive corneal disorder that causes thinning in the peripheral cornea, usually in a band-like pattern. Unlike other corneal conditions, PMD affects the lower cornea, often resulting in irregular astigmatism and significant visual distortions.

At the Raleigh Contact Lens Institute, our doctors have extensive experience managing PMD. We provide advanced diagnostic technology, longer exam times, and personalized one-on-one care. A common treatment for PMD is the use of scleral contact lenses.

Using specialized instruments, we collect up to 240,000 corneal data points to design fully customized scleral lenses. These lenses vault over the cornea, masking areas of thinning and distortion, and restoring clear, stable vision for patients with PMD.

Treatment Options for PMD

While there is no permanent cure for pellucid marginal degeneration (PMD), several treatment options are available to manage symptoms, improve vision, and enhance quality of life.
  • Scleral Contact Lenses - Large-diameter scleral lenses vault over the cornea, creating a smooth optical surface that compensates for the irregular shape caused by PMD.
  • Rigid Gas Permeable (RGP) Lenses - In some cases, RGP lenses may improve vision, though they are often less effective in advanced stages of PMD.
  • Corneal Cross-Linking - When PMD is progressing, cross-linking can help strengthen the cornea and reduce the risk of further thinning.
  • Intacs - Intracorneal ring segments can be implanted to reshape and stabilize the cornea, offering improved vision for selected patients.
  • Corneal Transplant -In severe cases where other treatments fail, a corneal transplant (keratoplasty) may be necessary to restore vision.
