    摘要: A method for fitting and designing an ophthalmic lens for a presbyope that yields improved visual acuity in general, and takes into account individual fitting characteristics. More specifically, a method for fitting and designing a contact or intraocular lens which takes into account material properties of the lens by observing the “print through” associated with the lens as an indicator of the topography of the lens. The term “print through” is used to refer to any change in lens topography on the front surface of the lens as a result of changes in topography on the back surface of the lens. If a significant amount of “print through” is observed, this generally indicates that the multifocal function of the lens is properly being performed. In such a situation, the clinician can then adjust the add power to the desired level. If there is not a significant amount of “print through”, this generally indicates that the multifocal function of the lens is not properly being performed. In this latter situation, by observing the reduced “print through” associated with such a lens, the clinician can instead bias one lens of a lens pair for distance power and the other lens of a lens pair for near power. Alternatively, each lens of the lens pair can be biased for some combination of distance power and near power.

    摘要: A system and method is provided for integrating corneal topographic data and ocular wavefront data with primary ametropia measurements to create a soft contact lens design. Corneal topographic data is used to design a better fitting soft contact lens by achieving a contact lens back surface which is uniquely matched to a particular corneal topography, or which is an averaged shape based on the particular corneal topography. In the case of a uniquely matched contact lens back surface, the unique back surface design also corrects for the primary and higher order optical aberrations of the cornea. Additionally, ocular wavefront analysis is used to determine the total optical aberration present in the eye. The total optical aberration, less any corneal optical aberration corrected utilizing the contact lens back surface, is corrected via the contact lens front surface design. The contact lens front surface is further designed to take into account the conventional refractive prescription elements required for a particular eye. As a result, the lens produced exhibits an improved custom fit, optimal refractive error correction and vision.

    摘要: A method is provided which is used to design soft contact lens via corneal topographic analysis. The topography of the cornea is matched to a corresponding topography of a soft contact lens. A geometrical transformation which maps the corneal elevation onto the back surface of an unflexed soft contact lens is used to minimize errors induced by flexure of the lens. The mapping transformation takes into account the effects of flexure. As a result, the contact lens has a back surface with a curvature which matches the specific elevations of the cornea, while the front surface can be spherical or any desired symmetrical or asymmetrical shape.

    摘要: An ophthalmic lens provides a cumulative ratio of distance to near focal length that is predominantly distance correction under high illumination, nearly evenly divided under moderate illumination, and favoring again distance vision correction under low level illumination. The lens is specifically adjusted to match the patient's pupil size as a function of illumination level, in the preferred embodiment by applying pupil size parameters as a function of age. This lens has the properties of matching both the distribution of near and distance focal vision correction to the type of human activity typically undertaken in various illumination conditions, as well as matching particular lens dimensions to suit the size of the pupil as a function of illumination intensity.
