1. An lens for altering the refractive properties of an eye, comprising:
- a polymerized first portion formed from a first material, at least a portion of said first portion positioned substantially adjacent a first surface of said lens; and
a second portion formed from an unpolymerized second material, at least a portion of said second portion positioned substantially adjacent a second surface of said lens;
wherein at least a portion of said second material is adapted to increase in volume, when exposed to energy selected from the group consisting of laser light, a chemical and thermal heat or decrease in volume, when exposed to a second energy, while the volume of said first material remains substantially unchanged.

7. A method producing a lens to alter the refractive properties the eye, comprising the steps of
forming a first portion of the lens having a first material therein, fixing the volume of the first material, forming a second portion of the inlay adjacent the first portion, the second portion having an unpolymerized second material therein, and exposing the second material to energy to change the configuration of the second portion.

14. A device for altering the refractive properties of an eye, comprising:
-
an unpolymerized material adapted to be affixed to a lens;
wherein a first surface of said lens is adapted to be positioned adjacent a surface of the cornea and said unpolymerized material is adapted to be positioned substantially adjacent a second surface of said lens; and
wherein at least a portion of said unpolymerized material is adapted to increase in volume, when exposed to energy selected from the group consisting of laser light, a chemical and thermal heat, while the volume of said lens remains substantially unchanged. - View Dependent Claims (15, 16, 17, 18)

19. A device for altering the refractive properties of an eye, comprising:
-
an unpolymerized material adapted to be affixed to a lens;
wherein said lens portion is adapted to be positioned in the anterior or posterior chamber of the cornea and said unpolymerized material is adapted to be positioned substantially adjacent a surface of said lens; and
wherein at least a portion of said unpolymerized material is adapted to increase in volume, when exposed to energy selected from the group consisting of laser light, a chemical and thermal heat, while the volume of said lens remains substantially unchanged. - View Dependent Claims (20, 21, 22)
