Abstract: An improved single lens comprising: a continuous change in lens curvature going downwards; a front and a back surfaces; an upper part which front and back surfaces are top zones of front and back surfaces, covering at least the half of respectively front and back surfaces, and where the two top zones are aligned to each other such that the effective power of the upper part of the lens is constant; a lower part used for viewing near objects which front and back surfaces are lower zones of front and back surfaces, the front and back lower zones comprising each a surface zone where top to bottom increasing curvature of each surface zone is provided and where the two front and back lower zones are aligned to each other such that the maximum difference of the effective power of the lower part of the lens and the effective power of the upper part of the lens is comprised between 0 and 0.5 Diopter.

Abstract: A method for stabilizing contact lenses includes providing a lens design with a nominal set of stabilization zone parameters, applying a merit function to the lens design based on balancing moments of momentum, and creating a contact lens design with improved stabilization based on the application of the merit functions to the lens design with a nominal set of stabilization zone parameters.

Abstract: Contact lens designs are provided with improved stabilization wherein the moments of momentum are balanced.

Abstract: Stabilized contact lenses have unconventional stabilization zones such as with the bulk of their length lying beneath the horizontal axis of the lens, a differing rate of change of slope (from peak) in one direction relative to the other, and a different height profile above the horizontal axis than below the horizontal axis.

Abstract: Methods and devices are provided for providing access through tissue to a surgical site. Generally, the methods and devices allow adjustment of a surgical access port's longitudinal length. In one embodiment, a surgical access port is provided that includes a housing having a cannula distally extending therefrom. The housing can be configured to cut a proximal portion of the cannula to adjust a longitudinal length of the cannula and hence of the surgical access port. In another embodiment, a surgical access port is provided that includes a cannula formed of a plurality of modular segments removably coupled together. One or more of the segments can be configured to be removable from the cannula to change the cannula's longitudinal length.

Abstract: Methods and devices are provided for providing surgical access into a body cavity. A surgical access port is provided that has an adjustable longitudinal length, such as by being formed from multiple segments configured to move relative to one another. An anchor can be coupled to a distal end of the surgical access port to help secure the surgical access port within a tissue opening by engaging a distal side of the tissue. Optionally, the anchor can be removably coupled to the distal end of the surgical access port, thereby allowing any one of a plurality of anchors to be selectively coupled thereto.

Abstract: The invention provides a method of fitting lenses that results in correction of not only low and high order ocular aberrations, but that additionally provides correction for the effects of cortical influences, or neuro-adaptive influences.

Abstract: The invention provides ophthalmic lenses useful in preventing myopia progression. The lenses of the invention provide substantially constant distance vision power zone in the center of the optic zone surrounded by a zone that provides positive longitudinal spherical aberration.
