We evaluated 500 subjects (1,000 eyes) who were habitual users of soft contact lenses. Neovasculariza-tion of the cornea was detected in 12% of eyes using soft contact lenses for more than two years. There were four distinct types of corneal neovasculariza-tion.

1. Silent neovascularization : subepithelial vascular invasion without corneal edema. No subjective symptoms. 2. Focal epithelial edema: focal subepithelial vascular invasion with corres-ponding epithelial edema. No subjective symptoms.3. Upper limbal infiltration: subepithelial vascular invasion towards the zone of corneal infiltration parallel to the limbus.
