Pellucid Marginal Degeneration Treatment in Newport Beach, 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.

Newport Beach's coastal environment can influence how pellucid marginal degeneration presents and responds to treatment. Factors like UV exposure, wind, and marine air quality are considered in our evaluation and management approach.
