Methods and devices are described that are needed to design and fabricate modified surfaces on contact lenses or on corneal tissue that correct the eye's optical aberrations beyond defocus and astigmatism. The invention provides the means for: 1) measuring the eye's optical aberrations either with or without a contact lens in place on the cornea, 2) performing a mathematical analysis on the eye's optical aberrations in order to design a modified surface shape for the original contact lens or cornea that will correct the optical aberrations, 3) fabricating the aberration-correcting surface on a contact lens by diamond point turning, three dimensional contour cutting, laser ablation, thermal molding, photolithography, thin film deposition, or surface chemistry alteration, and 4) fabricating the aberration-correcting surface on a cornea by laser ablation.

A display device is mounted on and / or inside the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. The projected light propagates through the pupil but does not fill the entire pupil. In this way, multiple sub-displays can project their light onto the relevant portion of the retina. Moving from the pupil to the cornea, the projection of the pupil onto the cornea will be referred to as the corneal aperture. The projected light propagates through less than the full corneal aperture. The sub-displays use spatial multiplexing at the corneal surface. Various electronic devices interface to the eye mounted display.

This invention includes a wettable biomedical device containing a high molecular weight hydrophilic polymer and a hydroxyl-functionalized silicone-containing monomer.

A soft contact lens containing a silicone-hydrogel made by curing a reaction mixture containing a silicone-containing monomer.

A head mounted support system for a head mounted apparatus. The apparatus includes a monocular display with a wireless communications interface, a user input device, a transmitter, receiver and a controller. The controller is configured to control the transmitter for sending and receiving control signals to and from an external device via the wireless interface. The monocular display is positioned relative to the user's dominant eye to display images to the user while occluding less than half of the user's maximum viewing space, while enabling the user to send and receive audible information or music. The head mounted support system may include an ear loop, and a housing for storing one or more functional components of the apparatus.

This invention relates to wettable biomedical devices comprising amphiphilic block copolymers. The amphiphilic block copolymers are useful as internal wetting agents for biomedical applications, such as implantable devices, ophthalmic devices and in one embodiment, contact lenses.

A method and apparatus are disclosed for controlling optical aberrations to alter relative curvature of field by providing ocular apparatuses, systems and methods comprising a predetermined corrective factor to produce at least one substantially corrective stimulus for repositioning peripheral, off-axis, focal points relative to the central, on-axis or axial focal point while maintaining the positioning of the central, on-axis or axial focal point on the retina. The invention will be used to provide continuous, useful clear visual images while simultaneously retarding or abating the progression of myopia or hypermetropia.
