ABSTRACT:
An insertion device for an intra-ocular lens (IOL) has a bilaminar, lubricious coating on the surface which contacts the IOL as it is being inserted into the eye. The bilaminar coating includes a highly lubricious top coat, and a polymeric base coat which is both highly adherent to the surface of the insertion device, and which has functional groups capable of grafting the base coat to the top coat. In its completed form, the bilaminar coating is essentially permanent, and exceedingly lubricious when wet, allowing the IOL to be advanced smoothly and without damage through the insertion device. The top coat may include hyaluronan, or another material capable of providing the required lubricity.
