Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for reducing dysphotopsia effects, such as straylight, haloes and glare, in diffractive lenses. Exemplary ophthalmic lenses can include a diffractive profile that distributes light among a near focal length, a far focal length, and one or more intermediate focal length. The diffractive profile provides for minimized or zero step heights between one or more pairs of diffractive zones for reducing visual artifacts.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs). Exemplary ophthalmic lenses can include a plurality of echelettes arranged around the optical axis, having a profile in r-squared space. The echelettes may be non-repeating over the optical zone.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for reducing dysphotopsia effects, such as haloes and glare. Exemplary ophthalmic lenses may include a central zone with a first set of two echelettes arranged around the optical axis, the first set having a profile in r-squared space. A middle zone includes a second set of two echelettes arranged around the optical axis, the second set having a profile in r-squared space that is different than the profile of the first set. A peripheral zone includes a third set of two echelettes arranged around the optical axis, the third set having a profile in r-squared space that is different than the profile of the first set and the profile of the second set, the third set being repeated in series on the peripheral zone.

A system for forming a corneal implant includes a cutting apparatus, which includes a laser source that emits a laser and optical elements that direct the laser. The system includes a controller implemented with at least one processor and at least one data storage device. The controller generates a sculpting plan for modifying a first shape of a lenticule formed from corneal tissue and achieving a second shape for the lenticule to produce a corneal implant with a refractive profile to reshape a recipient eye. The sculpting plan is determined from measurements relating to the lenticule having the first shape and information relating to a refractive profile for a corneal implant. The controller controls the cutting apparatus to direct, via the one or more optical elements, the laser from the laser source to sculpt the lenticule according to the sculpting plan to produce the corneal implant with the refractive profile.

Corneal transplant procedures may involve suturing an implant of healthy corneal tissue to a recipient cornea. The sutures may cause unwanted deformation of the corneal implant and the recipient cornea. A supporting structure may be embedded into the corneal implant to enhance the stability of the corneal implant and the recipient cornea and to reduce the likelihood of unwanted deformation when the corneal implant is sutured to the recipient cornea. According to one embodiment, a corneal implant includes donor corneal tissue extracted from a donor cornea. The donor corneal tissue includes an interior channel formed at a depth below an anterior surface. The corneal implant includes a supporting structure formed from non-tissue material and positioned in the channel.

Certain embodiments are directed to lenses, devices and/or methods. For example, a lens for an eye having an optical axis and an aberration profile along its optical axis, the aberration profile having a focal distance and including higher order aberrations having at least one of a primary spherical aberration component C(4,0) and a secondary spherical aberration component C(6,0). The aberration profile may provide, for a model eye with no aberrations and an on-axis length equal to the focal distance: (i) a peak, first retinal image quality (RIQ) within a through focus range that remains at or above a second RIQ over the through focus range that includes said focal distance, where the first RIQ is at least 0.35, the second RIQ is at least 0.1 and the through focus range is at least 1.8 Diopters; (ii) a RIQ of 0.3 with a through focus slope that improves in a direction of eye growth; and (iii) a RIQ of 0.3 with a through focus slope that degrades in a direction of eye growth. The RIQ may be Visual Strehl Ratio or similar measured along the optical axis for at least one pupil diameter in the range 3 mm to 6 mm, over a spatial frequency range of 0 to 30 cycles/degree inclusive and at a wavelength selected from within the range 540 nm to 590 nm inclusive.

Contact lenses incorporate multifocal power profiles that at least one of slow, retard or preventing myopia progression. The lens includes a first zone at a center of the ophthalmic lens and at least one peripheral zone surrounding the first zone. The at least one peripheral zone has a different width and dioptric power than the first zone. The first zone and at least one peripheral zone are stepped or discontinuous. The multifocal power profile has substantially equivalent foveal vision correction to a single vision lens and has a depth of focus and reduced retinal image quality sensitivity that slows, retards, or prevents myopia progression.

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.

A method for using a laser to create a pocket in a patient's cornea is provided. The pocket is created using a femtosecond or a nanosecond laser. The laser ablates tissue within the cornea in a specific shape. The shape of the pocket can be determined by software to custom program a three-dimensional path of the laser. A variety of corneal pocket configurations or computer programmed shapes can be used to accommodate various corneal lens shapes and sizes. An intracorneal lens can then be inserted into the pocket, in order to correct the patient's vision.
