    摘要: Intraocular lenses are provided having a visible-light selective transmissive zone defined therein. The visible light-selective transmissive zone can be located near the lens center and designed to reduce the transmission of any wave-length of visible light specifically light in the blue light region having wavelength between approximately 400λ to 550λ. In one embodiment he IOLs are made from acrylates and the light absorbing compound is a yellow dye.

    摘要: Soft, flexible highly lubricious coatings for polymeric IOL insertion cartridges that allow IOLs to be easily inserted through small bore cartridges suitable for use with small (less than 3 mm) incisions are provided. These lubricious coatings allow IOLs to be inserted into the eye of a patient without the risk of lens damage or transfer of lubricants to the lens surface during implantation. Specifically, polymeric coatings comprising a matrix polymer having an equivalent weight greater than 5000 g/eq are used to form interpenetrating networks (IPN) on the surface of hydrophobic structural polymers. The IPNs thus formed entrap highly lubricious hydrophilic compounds within the IPN using multi-functional cross linkers.
