Abstract
This invention relates to intraocular lenses. More particularly, this invention relates to intraocular lenses that have the ability to alter the light refractive power in response to changes in the tension of the ciliary muscle or ciliary body of the eye or any other accommodative forces. Lenses of this invention are generally referred to as interfacial, i.e., lens properties being defined as the interface of two liquids having different refractive indices, refractive accommodating lenses (IRAL).

2. A method of correcting visual acuity by the use of an accommodating IRAL, the method comprising the steps of:
-
replacing a defective natural lens of an eye of a patient in need of such replacement with an accommodating IRAL; permitting the IRAL to accommodate the patient'"'"'s need to change the focal point of the eye by changing the diopter strength and thus the focal point of the IRAL wherein the diapter strength change of the IRAL is at least 2 diopters. - View Dependent Claims (3, 4)

-
replacing a defective natural lens of an eye of a patient in need of such replacement with an accommodating IRAL; permitting the IRAL to accommodate the patient'"'"'s need to change the focal point of the eye by changing the diopter strength and thus the focal point of the IRAL wherein the diapter strength change of the IRAL is at least 2 diopters; wherein the IRAL employs liquids having different refractive indices to define the interface. - View Dependent Claims (11, 12, 13)
