Effects of long-term contact lens wear on the cornea had worn contact lenses for approximately five years or more, a 30 to 50 μm reduction in central and peripheral corneal thickness has been recorded. Furthermore, the reduction was more pronounced in patients wearing hard contact lenses than in patients wearing soft contact lenses. Increased endothelial polymegethism is also found in long-term wearers of rigid gas permeable lenses as soon as one week after contact lens wear begins. This change is indicated by significant increases in Max/Min cell size ratio in contact lens wearers. Endothelial pleiomorphism is another factor that arises from long-term use of rigid gas permeable lenses; significant
