Abstract: A lens configured for implantation into an eye of a human can include an optic including transparent material. The optic can have an anterior surface and a posterior surface. Each of the anterior surface and the posterior surface can have a surface vertex. The optic can have an optical axis through the surface vertices. The lens can also include at least one haptic disposed with respect to the optic to affix the optic in the eye when implanted therein. The anterior and posterior surfaces can include aspheric surfaces. The posterior surface can have an aspheric shape that comprises a biconic offset by perturbations comprising an aspheric higher order function of radial distance from the optical axis. The posterior surface can have an absolute value of ratio Rx/Ry between 0 and 100 and an absolute value of ratio kx/ky between 0 and 100.

Abstract: Methods of vision correction that include implanting a first lens and a second lens of a lens pair. The methods include implanting the first lens into a first eye of the subject, the first lens configured with positive extended depth of field, and implanting the second lens into a second eye of the subject, the second lens configured with negative extended depth of field, where the second eye is different than the first eye.

Abstract: A lens configured for implantation into an eye of a human can include an optic including transparent material. The optic can have an anterior surface and a posterior surface. The anterior surface can be convex and the posterior surface can be concave such that the optic is meniscus shaped. Each of the convex anterior surface and the concave posterior surface can have a surface vertex. The optic can have an optical axis through the surface vertices and a thickness along the optical axis that is between about 100-700 micrometers. The lens can also include haptic portions disposed about the optic to affix the optic in the eye when implanted therein. The anterior and posterior surfaces can include aspheric surfaces.

Abstract: A first metrology method includes the steps of projecting a first image and a second image, aligning the first image and the second image to form an aligned image of a known size, and determining a dimension of a target object by comparing the aligned image to the target object. A second metrology method includes the steps of projecting a first image and a second image, aligning the first image and the second image to form an aligned image of a known size by synchronously adjusting a zoom factor for projecting the first image and an angle for projecting the second image, and determining a dimension of a target object by comparing the aligned image to the target object.

Abstract: A metrology system includes a collinear array of uniformly spaced light elements for propagating parallel light beams. The parallel light beams assist in producing a light pattern on a target site. A method of measuring a dimension of a target site includes the steps of projecting uniformly spaced parallel light beams to form a light pattern having uniformly spaced elements on the target site, aligning the light pattern such that a maximum number of the uniformly spaced elements is positioned along the dimension; and counting the maximum number of the uniformly spaced elements positioned along the dimension.

Abstract: A system and method for determining endoscopic dimensional measurements including a projector assembly comprising a light source for projecting light through a telecentric lens and into a surgical site, and a mask coupled to the projector assembly. Light projected from the light source projects through the mask. The projected light through the mask may be a collimated pattern which does not significantly change in size as a function of the distance to a projected plane. The projected light patterns may include multiple wavelengths of light for measurements of different features of tissue and may be produced using a laser in conjunction with a light shaping optical diffuser, or using a light emitting diode in conjunction with a light shaping optical diffuser, or using a spatial filter. The projected light patterns may take the form of concentric rings with each ring representing a radius of a given dimension.

These systems, devices and methods allow for real-time highlighting of those points or regions that account for repositioning of the viewing instrument that is transmitting the images.
