Systems and methods for providing enhanced image quality across a wide and extended range of foci encompass vision treatment techniques and ophthalmic lenses such as contact lenses and intraocular lenses (IOLs). Exemplary IOL optics can include an aspheric refractive profile imposed on a first or second lens surface, and a diffractive profile imposed on a first or second lens surface. The aspheric refractive profile can focus light toward a far focus. The diffractive profile can include a central zone that distributes a first percentage of light toward a far focus and a second percentage of light toward an intermediate focus. The diffractive profile can also include a peripheral zone, surrounding the central zone, which distributes a third percentage of light toward the far focus and a fourth percentage of light toward the intermediate focus.

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 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 R.sub.x/R.sub.y between 0 and 100 and an absolute value of ratio k.sub.x/k.sub.y between 0 and 100.

An apparatus includes an intraocular pseudophakic contact lens having an optical lens and haptics extending radially from the optical lens. The optical lens is configured to at least partially correct a residual refractive error in an eye. The residual refractive error includes a refractive error that exists in the eye after implantation of an artificial intraocular lens in the eye.

Anterior surfaces of the haptics are configured to contact an inner capsular wall surface at the anterior leaflet. Posterior surfaces of the haptics include ridges configured to capture at least one edge of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens.

System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

An apparatus includes an intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens includes a first optical lens and multiple projections extending from the first optical lens.
