Fluidic module for accommodating soft contact lens
First Claim
1. An accommodating contact lens comprising:
- an optical reservoir comprising an anterior membrane and a posterior membrane; and
an outer reservoir fluidically coupled to the optical reservoir with a channel,wherein the anterior membrane comprises a variable thickness profile to inhibit aberrations,wherein the accommodating contact lens comprises a soft contact lens material disposed over the anterior membrane and wherein an index of refraction of the soft contact lens material approximates an index of refraction of the anterior membrane in order to inhibit optical effects of the variable thickness profile of the anterior membrane.

Abstract
A meniscus shaped lens module comprises one or more structures that decrease an amount of pressure or force to move one or more surfaces of the lens module and increase a separation distance of anterior and posterior surfaces of the module in order to provide an increase in optical power. A lens structure of the module comprises one or more of a pattern of a surface of a central chamber, a meniscus, a reduced diameter or a soft material in order to provide increased amounts of curvature of an outer contact lens surface with decreased amounts of pressure. The pattern can be formed in one or more of many ways, and may comprise one or more of folds, patterning, bellows or concertinaed surface of an optically transmissive material having a substantially uniform thickness such as a sheet of a membrane material.
