Abstract The influence of the permanent wear of rigid high Dk-lenses (nominal Dk 71 or 92) with elliptical geometry on the corneal endothelium was assessed. For this purpose the endothelium of 16 patients was compared by specular microscopy before and after the permanent wear. The wearing time of the lenses varied between 7 and 24 months. Computerized morphometric analysis of the photographs revealed that the variability in cell size (polymegathism) and in cell shape (pleomorphism) did not change during the wearing period. It is suggested that this is due to the high gas-permeability and the elliptical geometry of the contact lenses.
