A multifocal ophthalmic lens wherein a first surface of the lens is shaped to form a surface power map and a second surface of the lens is shaped to form a second surface power map. The first surface power map and the second surface power map together form a lens power map. The first surface power map, the second surface power map, or the lens power map comprises a spiral. The spiral has a variation across at least a portion of the lens. Methods of making and using such lenses are also provided.

Multifocal ophthalmic lenses and related methods

A method of designing a fluid-filled contact lens () is described. The method involves generating a computational model that includes a fluid-filled lens () and the shape of a cornea causes deformation of an internal structure of the fluid-filled lens () to generate a deformed, fluid-filled lens () with altered optical properties. The method also includes modelling () the optical properties of the deformed, fluid-filled lens (). The shape of the fluid-filled lens () is then adjusted () to reduce the effects of the deformation on the optical properties. This is referred to as an adjusted fluid-filled lens (). A corresponding off-eye lens design is generated (based on the adjusted fluid-filled lens design.

Method of designing a fluid-filled contact lens

The present disclosure concerns a tuneable ophthalmic lens. The tuneable ophthalmic lens comprises an activated state and a deactivated state. The ophthalmic lens further comprises a central chamber. The ophthalmic lens also comprises a fluid reservoir, the fluid reservoir being in fluid communication with the central chamber. The fluid reservoir comprises a pump for pumping fluid between the fluid reservoir and the central chamber. In the deactivated state the central chamber is substantially empty of fluid. In the activated state the central chamber is not substantially empty of fluid.

Tuneable ophthalmic lens

Contact lenses that have an ion-impermeable portion and an ion-permeable portion that are able to move on the eye without binding to the eye are described. The contact lenses exhibit an average ionoflux transmittance of at least 1.34&#xd7;10mm/min. One or more electronic components can be included in the contact lenses. Methods of making the contact lenses are also described.
