摘要： An intraocular lens for correcting or reducing the astigmatism of a cornea includes an optical element that has optical properties and characteristics that make it tolerant of rotational misalignment, when compared to a comparable lens having a uniform astigmatism orientation across its entire optical element, leading to more relaxed tolerances for a surgeon that implants the lens. The optical element of the toric ophthalmic lens has meridians associated therewith, including a high power meridian and a low power meridian orthogonal to the high power meridian. The optical element has at least one radially modulated meridian along which power monotonically varies with increasing radial position.

摘要： An intraocular lens for providing a subject with vision at various distances includes an optic having a first surface with a first shape, an opposing second surface with a second shape, a multifocal refractive profile, and one or more diffractive portions. The optic may include at least one multifocal diffractive profile. In some embodiments, multifocal diffractive and the multifocal refractive profiles are disposed on different, distinct, or non-overlapping portions or apertures of the optic. Alternatively, portions of the multifocal diffractive profiles and the multifocal refractive profiles may overlap within a common aperture or zone of the optic.

摘要： 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) modeling 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.

摘要： An intraocular lens is disclosed, which includes a diffractive element with a relatively low add power. The add power may be less than about 2 Diopters, may be less than about 1 Diopter, or may be in the ranges of 0.5 to 2.5 Diopters, or 1.0 to 2.0 Diopters, or 1.5 to 2.0 Diopters, or 1.0 to 1.5 Diopters. The low-add-power diffractive element increases the depth of the focus of the intraocular lens, for example, compared to a similarly shaped intraocular lens without the diffractive element. In one embodiment, the depth of focus is defined in terms of a threshold MTF value at a particular spatial frequency. The threshold may be an absolute threshold, such as 0.10, 0.15, 0.17, 0.20, 0.25 or 0.30, or may be a relative threshold, such as a particular percentage of the peak value. The spatial frequency may be 25 line pairs per mm, 50 line pairs per mm, 100 line pairs per mm, or any suitable value.
