摘要:
A contact lens assembly has a central lens and a circumscribing flange, the lens having an eye contact surface shaped generally to a radius of curvature of a cornea of an eye. The flange comprises a sterile sponge-like liquid absorbent flexible material having a central aperture for fitting snugly about an outer circumference of the lens and extending radially outward therefrom. The flange may include an inner attachment ring for attachment to the outer circumference of the central contact lens.
