Intraocular lens system with injectable accommodation material

摘要

The invention relates to a intraocular lens system having a flexible anterior lens accommodation material behind the lens. The accommodation material may comprise of one or more macromers, which, when polymerized, adjust the properties of the accommodation material. The anterior lens is flexible such that the curvature of the lens changes during accommodation. The anterior lens may be used alone or in combination with a posterior lens.

主权项

1. An intraocular lens system comprising:
an anterior membrane lens; an accommodation material wherein the accommodation material is capable of being placed behind the anterior lens after the anterior lens has been inserted into a capsular bag of a patient, said anterior lens capable of change in curvature during accommodation of the accommodation material, and wherein said accommodation material comprises macromers dispersed therein, said macromers capable of stimulus induced polymerization, wherein said accommodation material has an elastic modulus of from about 50 to about 1000 Pa, and wherein the anterior lens has an elastic modulus that varies across the anterior lens such that the anterior lens is stiffer at edges of the anterior lens than at a center of the anterior lens.
