Light microscopical and scanning electron microscopical examinations of deposits on disposable constant wear lenses.
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.
