Patent ID: 8771347

Claim:
An accommodating intraocular lens apparatus, comprising: a biocompatible polymer balloon of a first elastomeric material, the balloon fillable with an optically clear medium, the balloon configured for insertion into a capsular bag of an eye; and a valve including a self-sealing elastomeric patch of a different, second, cured elastomeric material that is stiffer than the first material, the elastomeric patch intimately formed with the balloon and being stiffer than the balloon, wherein the balloon has a thickness less than 100 μm, wherein the elastomeric patch has a thickness equal to or between 100 μm and 700 μm, thereby being thin enough to avoid contact with a posterior iris when implanted in an eye and sufficiently thick enough for self-sealing of needle punctures at nominal lens pressures for filling or adjusting said optically clear medium within the balloon, wherein the elastomeric patch includes a pre-formed slit.
