The implant comprises a lens 110 structured to be surgically implanted into or onto a living cornea 114 to change the optical properties of the associated eye and at least one added component covalently bonded to the lens structure and acting to promote the growth of epithelial cells of the cornea onto the lens and/or the adhesion of the living cornea to the lens. In one embodiment, at least a part of the lens (other than the added component) comprises a mixture of one or more synthetic polymer and one or more naturally occurring materials while, in a second embodiment, the added component is fibronectin or epidermal growth factor or derivatives/mixtures thereof. Other added components are specified with regard to the first embodiment and the synthetic polymer may particularly be a hydrogel-forming polymer. <IMAGE> |
