Deformable Intraocular Lenses and Lens Systems
An intraocular lens includes a deformable optic, a rigid optic, and a support structure. The deformable optic is disposed about an optical axis and comprises a solid material and a deformable surface. The rigid optic is disposed about the optical axis and comprises a solid material and a rigid surface. The support structure is operably coupled to at least one of the optics for pressing the deformable surface and the rigid surface together in response to or in the absences of an ocular force, whereby at least a portion of the deformable surface changes shape such that the optical power of the at least a portion of the deformable surface and/or the intraocular lens changes by at least 2 Diopter.

24 . A method of providing accommodation, comprising:
providing an intraocular lens, comprising:
a deformable optic disposed about an optical axis comprising a solid material and a deformable surface;
a rigid optic disposed about the optical axis comprising a solid material and a rigid surface; and
a support structure operably coupled to at least one of the optics;
implanting the intraocular lens into the eye of a subject; and
configuring the support structure for pressing the deformable surface and the rigid surface together in response to an ocular force, whereby at least a portion of the deformable surface changes shape such that the optical power of the at least a portion changes by at least 2 Diopter.
25 . The method of claim 24 , further comprising configuring the intraocular lens such that the radius of curvature of the deformable surface increases or decreases in response to the ocular force while the radius of curvature of the rigid surface remains substantially fixed.
26 . The method of claim 24 , further comprising configuring the intraocular lens so that an optical aberration of at least one of the deformable optic, the intraocular lens, and the eye is reduced in the response to the ocular force.
27 . The method of claim 24 , further comprising configuring the intraocular lens so that the deformable surface changes from a substantially spherical surface to an aspheric surface as the surfaces are pressed together.
28 . The method of claim 24 , further comprising configuring the intraocular lens so that the deformable surface changes from a first radius of curvature to a second radius of curvature different from the first radius of curvature when the surfaces are pressed together.
