Abstract:
An inexpensive, disposable soft contact lens for extended wear (DanaLens) has been developed. The lens is polymerized moulded in the wet state from hydroxyethyl methylacrylate and hydroxyethyl acrylate. Twenty-two pairs of the lens have in an open study been worn permanently from 1 to 43 days. Light microscopical and scanning electron microscopical examinations of the used lenses showed: superficial deposits on the front surfaces of the lenses of a mucous-like, easily removable material. Neither bacteria nor fungi were demonstrated.
