    摘要: A ophthalmic lens for inhibiting progression of myopia includes a central zone and an annular zone. The annular zone includes subsurface optical elements formed via laser-induced changes in refractive index of a material forming the annular zone. The subsurface optical elements are configured to modify distribution of light to the peripheral retina of a user so as to inhibit progression of myopia.

    摘要: Ophthalmic lenses and related methods provide a longitudinal chromatic alteration for an eye to provide the eye with a stimulus to inhibit myopia progression or reverse myopia. An ophthalmic lens configured to inhibit progression of myopia in an eye or reduce myopia in the eye includes a subsurface optical structure. The ophthalmic lens is formed from a transparent material having a lens material refractive index. The subsurface optical structure includes refractive index spatial variations relative to the lens material refractive index to provide a chromatic alteration to reduce axial growth of the eye or decrease the axial length of the eye.

    摘要: Example embodiments include methods for forming a subsurface optical structure in an ophthalmic lens. The method may include defining a phase-wrapped wavefront for causing the ophthalmic lens to diffract light to multiple focal points; defining a spherical wavefront configured for inducing a spherical aberration in the ophthalmic lens; and generating, based on the wavefronts, energy output parameters for forming a subsurface optical structure in the ophthalmic lens using an energy source, wherein the subsurface optical structure is configured to correct presbyopia by providing extended depth of focus that produces increased intermediate vision quality. Also disclosed are ophthalmic lenses with Fresnel rings that effect a phase-wrapped wavefront with a spherical aberration.

    摘要: Calibration of laser pulse powers used to form subsurface optical structures in an ophthalmic lens is accomplished via generation of a feedback signal indicative of pulse energy absorption. A system for forming subsurface optical structures within an ophthalmic lens includes a laser pulse source, a laser pulse power control assembly, a scanning assembly, a detector, and a control unit. The laser pulse power control assembly is operable to selectively control an energy of respective laser pulses. The detector is configured to generate a feedback signal indicative of an energy absorbed by the ophthalmic lens from a first laser pulse. The control unit is configured to control operation of the laser pulse power control assembly to selectively control an energy of a second laser pulse based on a selected energy of the second laser pulse, a selected energy of the first laser pulse, and the feedback signal.

    摘要: Scopes for viewing interior chambers of the eye include a refractive hydrogel polymer button formed by femtosecond laser micro-machining. The refractive button is sandwiched between two transparent plates and mounted on an ocular adapted to be placed directly on the cornea. A physician may look directly through the scope to see anatomical structures at very steep angles within the eye, such as to function as a gonioscope when viewing the anterior chamber angle. The scopes can be modified for viewing a variety of anatomical structures within the eye, and can also be used in conjunction with treatments such as by guiding injections or laser procedures. The refractive button has at least one region with a wavefront pattern of linear steps formed therein. Multiple regions with different wavefront patterns provide the physician with greater flexibility. The refractive button may be rotated relative to the ocular to further customize the image.

    摘要: Embodiments include methods and systems forming optical structures in an ophthalmic lens for improving a patient's vision by accessing a prescription for the patient; generating a variable wavefront based on the prescription; phase wrapping the first variable wavefront, wherein phase wrapping the first variable wavefront includes collapsing the first variable wavefront to a phase-wrapped wavefront having a predetermined phase height; and generating, based on the phase-wrapped wavefront, energy output parameters for forming an optical structure in the ophthalmic lens using an energy source.
