ABSTRACT:
Compositions useful to at least partially correct an effect of ametropia in a mammalian eye are disclosed. Such compositions comprise a plurality of particles sized and adapted to be placed in proximity to the outer surface of the cornea of a mammalian eye to at least partially correct an effect of ametropia in the mammalian eye. Each of the plurality of particles carries a complete hologram, preferably a complete hologram which holds all the information needed to at least partially correct the effect of ametropia in the mammalian eye. A particularly useful method of administering the plurality of particles to a mammalian eye is to use an additional component in an amount effective to act as a carrier for the plurality of particles. In one embodiment, this carrier component is an ophthalmically acceptable, aqueous-based liquid. Methods for using such compositions to at least partially correct an effect of ametropia in the mammalian eye, and methods for producing such compositions are also disclosed.
