Hydrophilic AIOL with bonding

摘要

An accommodating intraocular lens comprises a first lens component, a second lens component, and an adhesive between portions of the two lens components. The cured adhesive bonds the lens components to form a fluid chamber. The lens components are bonded to one another along a seam which extends circumferentially along at least a portion of the lens components. The lens components may comprise the same polymer material. The cured adhesive also comprises the polymer or a prepolymer of the polymer to provide increased strength. The polymer is hydratable such that the lens components and the cured adhesive therebetween can swell together to inhibit stresses between the lens components and the cured adhesive.

1. A method of manufacturing an accommodating intraocular lens, the method comprising:
providing a first lens component comprising a polymer, the first lens component comprising a first inner surface region extending discontinuously and circumferentially around a center of the first lens component and a first outer surface region extending circumferentially around the first inner surface region; providing a second lens component comprising the polymer, the second lens component comprising a second inner surface region extending discontinuously and circumferentially around a center of the second lens component and a second outer surface region extending circumferentially around the second inner surface region; bonding the first inner and outer surface regions of the first lens component to the second inner and outer surface regions of the second lens component with an adhesive comprising a prepolymer of the polymer, wherein the prepolymer is cured to bond the first lens component to the second lens component with the cured prepolymer extending between the first and second inner surface regions and between the first and second outer surface regions; thereby creating an inner seam and an outer seam, respectively, the inner seam defining an inner fluid chamber enclosed therewithin and the inner and outer seams defining an outer haptic chamber enclosed therebetween, the outer haptic chamber being in fluid communication with the inner fluid chamber; and hydrating the bonded first lens component, the second lens component, and the cured prepolymer to provide a hydrated, soft accommodating intraocular lens comprising the polymer.
