Abstract
The present invention is directed to adjustable chromophore compounds and materials (e.g., ophthalmic lens materials) incorporating those compounds. The adjustable chromophore compounds include a chemical moiety that structurally changes upon exposure to predetermined electromagnetic radiation (e.g., two photon radiation) as well as lens materials, particularly intraocular lens materials that incorporate those compounds.

1-21. (canceled)
A method of adjusting a lens, the method comprising:
- providing a lens having a compound of the formula:
- B—X;
- wherein:
- i) B is a base chromophore compound;
- and
- ii) X is an adjustable chemical moiety;
- exposing the compound B—X to predetermined electromagnetic radiation thereby forming the compound:
- B—C;
- wherein:
- i) the compound B—C provided greater light absorption than the compound B—X;
- and
- ii) the remaining chemical moiety (C) includes a conjugated double bond.

A method of adjusting a lens, the method comprising:
- providing a lens having a compound of the formula:
- B—X or B—C
- as part of the reactive system:
- B—X⇄B—C
- wherein:
- i) B is a base chromophore compound;
- ii) X is an adjustable chemical moiety that forms remaining chemical moiety (C) upon exposure to first predetermined electromagnetic radiation thereby forming the compound B—C;
- iii) the compound B—C provides greater light absorption than the compound B—X;
- and iv) the remaining chemical moiety (C) includes a conjugated double bond;
- and
- v) the compound B—C forms the compound B—X upon exposure to second predetermined electromagnetic radiation either with or without the aid of a separable group (S)and exposing either:
- i) the compound B—X to the first predetermined electromagnetic radiation to form the compound B—C;
- or ii) the compound B—C to the second predetermined electromagnetic radiation to form the compound B—X.
