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.
Yorba Linda residents managing pellucid marginal degeneration benefit from our efficient, comprehensive appointment structure—thorough evaluation and clear treatment planning in visits designed to respect your time.
