Abstract
The present invention includes systems and methods for improving vision by reshaping the cornea of an eye. The systems and methods include two or more contact lenses configured to be at least temporarily worn on the cornea at the same time, and to exert force on the cornea to change its shape. After the shape of the cornea has been appropriately changed, a contact lens with the appropriate configuration may be worn as needed to maintain the new shape of the cornea.
Claims16
A system to reshape the cornea of an eye, comprising:
- a first contact lens;
- and
- a second contact lens, wherein:
- said first contact lens and said second contact lens are configured to reshape the cornea while being worn simultaneously on the eye,
- said second contact lens is configured to be worn independently on the eye, and
- said first contact lens is more rigid than said second contact lens.
3 more elements
