  • Publication number: 20130201444
    Abstract: Multifocal contact lenses and methods and uses are described. The multifocal contact lenses include an optic zone. The optic zone has an aspheric power profile that provides a near vision refractive power and a distance vision refractive power, and provides an Add power that corresponds to the difference between the near vision refractive power and the distance vision refractive power. The multifocal contact lenses can improve binocular vision of presbyopic subjects by being prescribed such that the non-dominant eye contact lens is over-corrected for distance vision, and both multifocal contact lenses are under-corrected for the Add power requirement of the subject. Batches and sets of multifocal contact lenses are also described.

  • Patent number: 7730497
    Abstract: The present invention provides a common interface among device drivers 5 operating in the kernel 8, for increasing data transfer speeds and improving data integrity. A common interface driver 7 is provided among device drivers 5, which control devices 6 connected to a computer. The common interface driver 7 operates in the kernel mode 8 and provides an interface with the application program 4. The common device driver 7 receives and analyzes commands from the application program 4 and outputs instructions to each of the device drivers 5.

  • Patent number: 7416300
    Abstract: Optical coherence tomography (OCT) systems are used to measure lenses. The present methods use an OCT system to obtain one or more images of a lens. For example, an OCT system can be used to obtain section images, surface images, or combinations of section images and surface images of vision correcting lenses, such as contact lenses, intraocular lenses, corneal onlay lenses, corneal inlay lenses, and spectacle lenses, or non-vision correcting lenses, such as optical instrument and diagnostic instrument lenses. The images can be used to determine features of the lens, such as surface shapes, thicknesses, curvatures, lens powers, and edge profiles, among others. The present methods include lens metrology methods, lens design methods, and lens manufacturing methods.
