Visual aids and associated methods for improving the eye sight of low vision patients are provided. Generally, the devices of the present disclosure address the needs of age-related macular degeneration (AMD) and other low vision patients by providing a magnified retinal image while keeping a large visual field of view. Further, the devices of the present disclosure allow direction of the magnified retinal image away from damaged portions of the retina and towards healthy, or at least healthier, portions of the retina. The devices of the present disclosure are also configured for implantation within the eye using minimally invasive surgical procedures. Methods of utilizing the devices of the present disclosure, including surgical procedures, are also provided.

Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or optical tissues is performed to address various types of vision correction.

An accommodating intraocular lens implant is provided that includes (a) a bowl-shaped posterior component and (b) an anterior component, which includes an anterior floating lens unit, which includes an anterior lens; a circumferential rim; and levers, which connect the anterior floating lens unit to the circumferential rim, such that the anterior floating lens unit is movable toward and away from the circumferential ring in an anterior-posterior direction. The bowl-shaped posterior component and the anterior component are distinct from each other and not permanently fixed to each other, and are shaped so as to be assemblable together in situ in a human eye such that the circumferential rim contacts an interface region of an inner surface of the bowl-shaped posterior component, and the levers are pivotable about the interface region during motion of the anterior floating lens unit toward and away from the circumferential ring in the anterior-posterior direction.

An accommodating intraocular lens implant includes an anterior floating lens unit, a posterior lens unit, an anterior lens link, and an anterior rim link, which comprises an anterior rim jointed element. An anterior rim complex is disposed such that the anterior floating lens unit is movable toward and away from the anterior rim complex, in an anterior-posterior direction. A lever is connected (a) at a first longitudinal site along the lever, to the anterior floating lens unit by the anterior lens link, and (b) at a second longitudinal site along the lever, to the anterior rim complex by the anterior rim link. The lever, at a third longitudinal site along the lever, is in jointed connection with the posterior lens unit. The second site is longitudinally between the first and the third sites along the lever.

An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to die optical portions through the interlocked haptics. When installed in a natural lens capsule after the cataract extraction, the optical power of such IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle.

An accommodating intraocular lens construction includes a lens of fixed optical power to correct refractive error and a lens of variable power to restore accommodation of the eye, which variable lens can have two optical elements which either shift perpendicular to the optical axis, or which variable lens can have two elements which move along the optical axis. The accommodating intraocular lens has at least one haptic to provide transfer of movement to at least one of the optical elements and at least one additional haptic for sulcus fixation to provide limitation of movement of at least one component of the lens along the optical axis. The movement of the additional haptic is largely independent from the haptic for movement.

Fluidic glasses for correcting refractive errors of a human or animal are disclosed herein. The fluidic glasses includes at least one flexible fluidic lens having an outer housing and a flexible membrane supported within the outer housing, the flexible membrane at least partially defining a chamber that receives a fluid therein; and a fluid control system operatively coupled to the at least one flexible fluidic lens, the fluid control system configured to insert an amount of the fluid into the chamber of the at least one flexible fluidic lens, or remove an amount of the fluid from the chamber of the at least one flexible fluidic lens, in order to change the shape of the at least one flexible fluidic lens in accordance with the amount of fluid therein, thereby correcting the refractive errors of an eye of a human or animal.

A flexible fluidic mirror system and a hybrid fluidic optical system is disclosed herein. The flexible fluidic mirror system generally includes a flexible fluidic mirror having an outer housing and a flexible membrane supported within the outer housing, and a fluid control system operatively coupled to the flexible fluidic mirror.

A secondary foldable intraocular lens, IOL, (2) is provided that is surgically implanted in addition to at least one primary IOL (1) in the patient's pseudo-phakic eye. The secondary IOL (2) is arranged optically coaxial to the primary IOL (1) focusing a combined image onto the retina (5) of the patient's eye (4) additionally magnifying at least a central part of the image of the primary IOL (1) projected onto the macula (6) of the retina (5). The secondary IOL (2) comprises one or more haptics (7) for fixing and stabilizing it within the sulcus ciliaris (8) of the patient's eye (4)and an optically active portion (9) designed to project the image through the primary IOL (1) onto the retina (5). The optically active portion (9) of the secondary IOL (2) comprises a central optical portion (10) and a peripheral optical portion (11) extending around the central optical portion (10), forming two different, but coaxially positioned lenses from one block. The central optical portion (10) is designed to form a positive lens providing additional refraction of minimum 5D, up to maximum 25D to the refraction provided by the peripheral optical portion (11) of the secondary IOL (2).
