Abstract: A method for calculating the required power of a toric implant by using both the measured pre-operative corneal astigmatism and the predicted surgically-induced post-operative astigmatism. The surgically-induced post-operative astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required post-operative refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.

Abstract: The present invention provides an ophthalmic lens (e.g., an intraocular lens) having an optic with an anterior surface and a posterior surface, which exhibits a shape factor (defined as a ratio of the sum of the anterior and posterior curvatures to the difference of such curvatures) in a range of about −0.5 to about 4. In a related aspect, the shape factor of the optic lies in a range of about 0 to about 2. The above shape factors give rise to a plurality of different lens shapes, such as concave-convex, plano-convex and plano-concave.

Abstract: Contour-matching, aspheric lenticules are disclosed for implantation in a subject's cornea to correcting refractive errors. The lenticules include a photoablatable anterior surface and a posterior surface having an aspheric profile that can substantially match the asphericity exhibited by the corneal stromal surface, on which the lenticule is placed. The posterior surface can have a generally concave shape while the anterior surface can have a generally convex shape, though other shapes can also be utilized in some embodiments. In some embodiments, the asphericity of the lenticule's posterior surface can differ from an asphericity exhibited by the corneal stromal surface by less than about 50%, or preferably by less than about 20%.
