Abstract
A medical system that can direct energy onto a focal point located within a cornea. The system can vary the focal point of the energy through the cornea to create a column of denatured tissue within the cornea stroma layer. The denatured tissue modifies the visual acuity of the cornea.
Claims39
A medical system that can denature a cornea, comprising:
- an energy device that can direct energy to a focal point within the cornea;
- and,
- a movement device that moves the focal point of the energy.
A medical device that can denature a cornea, comprising:
- a plurality of energy devices that can each direct energy to a different focal point within the cornea;
- and,
- a controller that can select the energy devices so that the focal point of energy varies through the cornea.
A method for denaturing a cornea, comprising:
- directing energy onto a focal point within the cornea;
- and,
- varying the focal point of the energy.
