Ophthalmic dynamic aperture

An ophthalmic device, comprising:

• an electro-active element comprising a mostly transparent dynamic aperture having an alterable diameter and a mostly opaque annulus for providing an increased depth of field, wherein said electro-active element is in optical communication with an intraocular lens having an optical power for providing at least a partial correction of a refractive error of a user's eye,
• wherein said mostly transparent aperture provides a transmission approximately equivalent to the transmission of a neutral optical density filter of less than approximately 0.1, said mostly opaque annulus provides a transmission approximately equivalent to the transmission of a neutral optical density filter of approximately 0.3, or both;
• wherein said dynamic aperture can be altered remotely, and
• wherein the ophthalmic device is capable of being surgically implanted into said user's eye.

An ophthalmic device, comprising:

• a dynamic electro-active element, wherein the ophthalmic device is in optical communication with an intraocular lens having an optical power for providing at least a partial correction of a refractive error of a user's eye, said dynamic electro-active element including,
• an aperture;
• a first substrate;
• a plurality of electrodes disposed on a surface of said first substrate;
• a second substrate having a surface facing said surface of said first substrate;
• a single electrode disposed on said surface of said second substrate;
• and
• an electro-active material disposed between the facing surfaces of said first and said second substrates,
• wherein said plurality of electrodes provide said aperture,
• wherein said dynamic electro-active element can be altered remotely, and
• wherein the ophthalmic device is flexible and is surgically implantable into said user's eye through an incision of not more than about 1 mm-3 mm.

An ophthalmic device to be worn by a wearer, said ophthalmic device comprising:

• an aperture;
• a peripheral region;
• a first transparent electrode comprising a plurality of pixel regions and a second transparent electrode disposed over the first transparent electrode;
• an electro-active layer disposed between the first electrode and the second electrode, the electro-active layer comprising a material allowing for a variable transmission of light in the aperture and peripheral region;
• wherein said aperture provides a higher transmission of light than said peripheral region;
• and
• wherein the shape and size of the aperture is adjustable by way of a controller, a sensor, or both, and
• the shape of the aperture is adjustable to shapes other than a circle.
