Abstract
Corneal collagen crosslinking is used to alter a characteristic of the cornea, such as thickness or refractive index, to correct wavefront aberrations, including higher-order aberrations. A scanning laser or the like is used to perform the corneal collagen crosslinking by locally altering the optical path length (thickness, refractive index, or both).
Claims20
A method for correcting wavefront aberrations in a living eye, the method comprising:
- (a) illuminating the cornea to cause corneal collagen crosslinking;
- and
- (b) controlling the corneal collagen crosslinking such as to change a characteristic of the cornea to correct the aberrations.
A system for correcting wavefront aberrations in a living eye, the system comprising:
- a light source for illuminating the cornea to cause corneal collagen crosslinking;
- and
- a processor for controlling the light source to control the corneal collagen crosslinking such as to change a characteristic of the cornea to correct the aberrations.
