A variable focus intraocular lens (56) is provided that is a compound lens formed of two or more lenses (58, 60) attached together, and enclosing one or more closed central spaces or compartments (64) therebetween. When the lens is implanted inside the eye, the central space(s) contain sterile air, gas, and/or are at a reduced pressure (vacuum). If the power of the variable focus intraocular lens is to be changed, one or more of the central space(s) is opened (67) so that the aqueous humor enters the targeted lens compartment, and changes the power of the intraocular lens. The compartment can be opened either with a laser or surgically, e.g., through a weakened thin place in the wall of the central compartment, by removing a plug, by opening a valve, or the like. |
