Pellucid Marginal Degeneration Treatment in Irvine, California

Medically reviewed by Dr. Alexander Bonakdar, O.D. · Updated April 2026

Pellucid marginal degeneration (PMD) is a progressive corneal thinning disorder where the inferior peripheral cornea thins in a band pattern, causing the cornea above to protrude forward. Unlike keratoconus, which thins at the apex, PMD thins at the periphery. This creates a characteristic 'against-the-rule' or oblique astigmatism that is very difficult to correct with glasses or standard contact lenses. Scleral lenses are often the best non-surgical solution, vaulting over the entire irregular surface to provide clear, stable vision.

Irvine's screen-intensive work culture can influence how pellucid marginal degeneration symptoms are experienced throughout the day. We factor your digital lifestyle into our diagnostic and treatment recommendations.
