摘要: A diffractive multifocal lens is disclosed, comprising an optical element having at least one diffractive surface, the surface profile comprising a plurality of annular concentric zones. The optical thickness of the surface profile changes monotonically with radius within each zone, while a distinct step in optical thickness at the junction between adjacent zones defines a step height. The step heights for respective zones may differ from one zone to another periodically so as to tailor diffraction order efficiencies of the optical element, in one example of a trifocal lens, step heights alternate between two values, the even-numbered step heights being lower than the odd-numbered step heights. By plotting a topographical representation of the diffraction efficiencies resulting from such a surface profile, step heights may be optimized to direct a desired level of light power into the diffraction orders corresponding to near, intermediate, and distance vision, thereby optimizing the performance of the multifocal lens.

摘要: In certain embodiments, a system for performing refractive treatment of an eye comprises a laser, a printer, and a computer. The laser emits a laser beam to prepare the eye for the refractive treatment. The printer prints material onto a print area of a target. The printer comprises a printer head and a printer controller. The printer head directs the material onto the print area, and the printer controller moves the printer head to direct the material onto a specific location of the print area. The computer comprises a memory and processors. The memory stores instructions for a pattern for the target. The pattern is designed to provide the refractive treatment for the eye. The processors instruct the printer controller to move the printer head to print the material onto the print area according to the pattern.

摘要: 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.

摘要: The present invention discloses an ophthalmic device with a retinal vascularization monitoring system and associated methods. In some embodiments, the ophthalmic device can be a contact lens with a retinal vascularization monitoring system that can be used to monitor temporal changes of a pulsating vessel forming part of the retinal vascularization. Further, the retinal vascularization monitoring system may include elements for delivering a signal, including an audible and/or visual message, to the user that can be useful for identifying abnormal conditions such as a cardiac failure without delay. The audible and/or visual messages can be signals communicated to the user using one or both of the ophthalmic device and a wireless device in communication with the ophthalmic device.

摘要: A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

摘要: A multifocal ophthalmic lens has an optic zone that includes at least one first zone having a dioptric power that satisfies a distance refraction need of a patient; and at least one second zone having a dioptric power that is greater than the dioptric power of the at least first zone. The at least one first zone and the at least one second zone are configured so that 1) an image quality on the retina of the patient is superior to the image quality both in front of the retina and behind the retina, and 2) an image quality in front of the retina of the patient is superior to the image quality behind the retina. The multifocal ophthalmic lens prevents and/or slows myopia progression.

摘要: This invention describes strategies and devices for improving the visual experience while expanding the depth of field of presbyopic and pseudophakic patients. The invention describes strategies and devices for providing improved image quality and improved visual quality of patients employing simultaneous vision bifocal, trifocal or multifocal corrections or monovision. The invention describes strategies and devices for reducing the visibility of the defocused part of the retinal image generated by simultaneous vision bifocal and multifocal ophthalmic corrections and monovision. The invention describes strategies and devices that employ control of spherical aberration or other similar asphericities to reduce the visibility of defocused ghost images. The invention describes strategies and devices that ensure that negative defocus is always coupled with negative spherical aberration (or similar asphericity), and that positive defocus is always coupled with positive SA (or similar asphericity) as a means to reduce the visibility of defocused ghost images.
