A toric eye lens with an edge capable of designing a lens for preventing cataract without lowering the degree of freedom of lens design is realized. The toric eye lens is provided with a substantially flat portion in which the edge thickness of the optical portion is substantially constant in ...
Toric Intraocular Lens In subject area: Nursing and Health Professions Toric intraocular lenses are specialized lenses used for correcting preexisting regular keratometric astigmatism in the eye, particularly in cases where other methods are not sufficient. These lenses have a cylindrical correction on a...

Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing an enhanced toric lens which redirects and/or focuses light incident on the eye at oblique angles onto a periphera...
Referring first to FIG. 1, an eye 1 looks at a point located at infinity through its corrector lens 2 having an optical axis 3 passing through the center of rotation 0 of the eye, the axis of vision forming an angle U with the optical axis 3. Assuming that if U = 0 the ametropia...
