Ophthalmic lens having an extended depth of focus
In certain embodiments, an ophthalmic lens includes an optic having an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface includes a first zone extending from the optical axis to a first radial boundary and a second zone extending from the first radial boundary to the edge of the optic. The first zone includes an inner region and an outer region separated by a phase shift feature, the phase shift comprising a ridge extending outwardly from the inner region and the outer region.
MULTIFOCAL LENS HAVING AN OPTICAL ADD POWER PROGRESSION, AND A SYSTEM AND METHOD OF PROVIDING SAME
An apparatus, system and method including an ophthalmic lens having an optic with an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens further includes a first region having a first optical power and a second region having a second optical power. The ophthalmic lens further includes a third region having an optical power that progresses from the first optical power to the second optical power. The progression may be uniform or non-uniform. Each of the first, second and progression optical power may include a base power and an optical add power. Each of the first, second and progression regions may provide a first focus, a second focus and a plurality of third foci, respectively.
Aspheric optical lenses and associated systems and methods
Aspheric optical lenses (e.g., intraocular lenses and contact lenses) are provided. The intraocular lens includes a body portion defining an anterior optical surface and an opposing posterior optical surface. The anterior optical surface includes a central region surrounded by a first outer region and a second outer region. The central region has a first asphericity profile. The first outer region has a second asphericity profile that is different than the first asphericity profile of the central region. The second outer region has a third asphericity profile that is different than the second asphericity profile of the first outer region. The overall asphericity profile of the optical lens provides different depths of focus for different pupil sizes. The result is an optical lens that provides increased depth of focus or pseudo-accommodation while maintaining desired optical power and performance.
Lenses, Devices, Systems and Methods for Refractive Error
The present disclosure is directed to lenses, devices, methods and/or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and/or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and/or methods include embodiments that address foveal and/or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and/or refractive surgery.
Flexible electro-active lens
A lens including a flexible refractive optic having a fixed refractive index, an electro-active element embedded within the flexible refractive optic, wherein the electro-active element has an alterable refractive index, and a controller electrically connected to the electro-active element wherein when power is applied thereto the refractive index of the electro-active element is altered.
Semi-flexible posteriorly vaulted acrylic intraocular lens for the treatment of presbyopia
An intraocular lens having an optic and at least one semi-rigid, haptic connected to the optic, both of which may be acrylic. The intraocular lens can have a fixed longitudinal length, e.g., the same fixed length pre-operatively and post-operatively. The intraocular lens can resist deformation, despite contraction and relaxation of the ciliary muscle and fibrosis within the capsular bag, after implantation into the eye using, for example, by the semi-rigid haptics. The intraocular lens can be sufficiently flexible to be compressed from an original configuration to a compressed configuration for insertion into the eye through a small incision and return to the original configuration after implantation into the eye.
OPHTHALMIC LENSES WITH ENHANCED SURFACE AND METHODS OF FABRICATION THEREOF
An ophthalmic lens for providing enhanced vision includes a finished optic comprising a base optic and a membrane. The base optic has an anterior surface and an opposing posterior surface, at least one of the surfaces having a first value of a surface quality parameter. The base optic also includes a membrane including an inner surface and an outer surface, the inner surface covering one or more of the surfaces of the base optic. The outer surface has a second value of the surface quality parameter, wherein the second value is greater than the first value.
Multifocal ophthalmic lens
A method of designing a multifocal ophthalmic lens with one base focus and at least one additional focus, capable of reducing aberrations of the eye for at least one of the foci after its implantation, comprising the steps of: (i) characterizing at least one corneal surface as a mathematical model; (ii) calculating the resulting aberrations of said corneal surface(s) by employing said mathematical model; (iii) modelling the multifocal ophthalmic lens such that a wavefront arriving from an optical system comprising said lens and said at least one corneal surface obtains reduced aberrations for at least one of the foci. There is also disclosed a method of selecting a multifocal intraocular lens, a method of designing a multifocal ophthalmic lens based on corneal data from a group of patients, and a multifocal ophthalmic lens.
Intraocular lens
An intraocular lens including a flexible optic and at least one rigid plate haptic connected to the optic. The at least one rigid plate haptic can include a rigid structure. The at least one rigid plate haptic can be resistant to bending from pressure exerted on a distal end of the at least one haptic by contraction of the ciliary muscle. The intraocular lens can be a non-accommodating IOL having a longitudinal length that is fixed and configured to resist deformation by the action of the ciliary muscle. Various embodiments also include accommodating intraocular lenses.
