The present disclosure provides an ophthalmic lens that is disposed to balance coma aberrations if the lens, when inserted in a patient's eye, is decentered or tilted with respect to an optical axis of the patient's eye, and maintain a substantially diffraction-limited image quality if the lens, when inserted in the patient's eye, is centered with respect to the optical axis of the patient's eye. The lens may include an optic having an anterior surface and an opposing posterior surface disposed about an optical axis of the lens. One of the surfaces (e.g., the anterior surface) may have a semi-aspheric surface profile, which includes an inner region having a substantially spherical surface profile and extending radially from the optical axis of the lens to a first boundary, and an outer region having an aspherical surface profile and extending radially at least beyond the first boundary to a second boundary.

Ophthalmic lenses for balancing coma aberrations

The invention relates to remotely operated multi-component search robots for underwater search and rescue operations, and particularly suited for searches under ice.

Multi-component robot for below ice search and rescue

A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, an optic axis and at least one diffractive grating pattern. The diffractive grating pattern(s) are disposed on at least one of the anterior surface and the posterior surface. The diffractive grating pattern(s) includes zones corresponding to distance ranges from the optic axis. Each of the zones has a plurality of echelettes having a radius of curvature corresponding to a focal length. The radius of curvature for each of at least a portion of the zones is different from the radius of curvature for another of the zones.

Method and system for providing an intraocular lens having an improved depth of field

An accommodative intraocular lens (IOL) system is disclosed for insertion into an eye to provide accommodative vision, the system including a deformable air chamber filled with a transparent, low refractive index medium disposed between the first and second optics; and at least one haptic connected to the air chamber and configured to facilitate a change in the curvature of at least one surface of the chamber, such that when the lens system is positioned in an eye, cilliary muscle movements can alter the curvature of the air chamber and vary the overall lens power of the system.

Presbyopia-correcting IOL using curvature change of an air chamber

An ophthalmic lens includes an optical filter operable to filter out at least visible light having a wavelength less than 450 nm. The lens also includes a first diffractive structure adapted to produce a focus for visible light in a first wavelength range above 550 nm and to reduce longitudinal chromatic aberration to less than one diopter for incoming visible light in the first wavelength range. The lens also includes a second diffractive structure outside the first diffractive structure in a radial direction and adapted to produce a focus for visible light in a second wavelength range between 450 nm and 550 nm. The second diffractive structure is also adapted to reduce longitudinal chromatic aberration for incoming visible light in the second wavelength range to less than one diopter while allowing longitudinal chromatic aberration in the first wavelength range in an amount greater than the first diffractive structure.

IOL with varying correction of chromatic aberration

The present invention provides monofocal ophthalmic lenses that exhibit extended depth of field while providing sufficient contrast for resolution of an image over a selected range of defocus distances. In some embodiments, a lens of the invention can include a refractive surface having controlled surface modulations relative to a base profile. The surface modulations are designed to extend a depth of field of the lens such that a single image can be resolved, albeit with somewhat less contrast, over a range of distances greater than the focal region of a conventional lens. The ophthalmic lenses of the invention can be employed in various vision correction applications, including, but not limited to, intraocular lenses, contact lenses, instrastromal implants and other refractive devices.
