Same PMMA contact lenses worn for over 30 years: A case report

Abstract

Many, often asymptomatic, contact lens wearers have alterations of the corneal topography called corneal warpage. These topographic abnormalities are characterized by the presence of irregular astigmatism, loss of radial symmetry, and frequent reversal of the normal topographic pattern of progressive flattening of corneal contour from the center to the periphery. We describe a case in which the same pair of PMMA contact lenses was worn for over 30 years. The patient had no symptoms regarding her contact lenses, but on a visit for a posterior vitreous detachment, we found typical signs of corneal warpage, which resolved after 12 weeks of contact lens wear suspension
