The present invention relates to lenses that are capable of post-fabrication power modifications. In general, the inventive lenses comprise (i) a first polymer matrix and (ii) a refraction modulating composition that is capable of stimulus-induced polymerization dispersed therein. When at least a portion of the lens is exposed to an appropriate stimulus, the refraction modulating composition forms a second polymer matrix. The amount and location of the second polymer matrix may modify a lens characteristic such as lens power by changing its refractive index and/or by altering its shape. The inventive lenses have a number of applications in the electronics and medical fields as data storage means and as medical lenses, particularly intraocular lenses, respectively. |

A method and instrument to irradiate a light adjustable lens, for example, inside a human eye, with an appropriate amount of radiation in an appropriate pattern by measuring aberrations in the system containing the lens; aligning a source of the modifying radiation so as to impinge the radiation onto the lens in a pattern that corresponds to the aberration; and controlling the quantity of the impinging radiation whereby to decrease the aberration. The quantity of the impinging radiation is controlled by controlling the intensity and duration of the irradiation. The pattern is controlled and monitored while the lens is irradiated. |

A system for providing improved vision to a patient having undergone an intraocular lens implantation includes a device for measuring an aberration in an eye of a patient having an intraocular lens implanted therein. Computer software is resident on a processor and is adapted to calculate a refraction profile prescription for correcting the measured aberration. An apparatus is also provided for altering a refractive index of a sector of the intraocular lens in situ according to the calculated prescription. The method includes measuring an aberration in an eye of a patient having an intraocular lens implanted therein, calculating a refraction profile prescription for correcting the measured aberration, and altering a refractive index of a sector of the intraocular lens in situ according to the calculated prescription. |

The wavefront aberrator of the present invention includes a pair of transparent windows, or plates, separated by a layer of monomers and polymerization initiator, including a broad class of epoxies. This monomer exhibits a variable index of refraction across the layer, resulting from controlling the extent of its curing. Curing of the epoxy may be made by exposure to light, such as ultraviolet light. The exposure to light may be varied across the surface of the epoxy to create a particular and unique refractive index profile. |

An Eyeglass Manufacturing Method Using Epoxy Aberrator includes two lenses with a variable index material, such as epoxy, sandwiched in between. The epoxy is then cured to different indexes of refraction that provide precise corrections for the patient's wavefront aberrations. The present invention further provides a method to produce an eyeglass that corrects higher order aberrations, such as those that occur when retinal tissue is damaged due to glaucoma or macular degeneration. The manufacturing method allows for many different applications including, but not limited to, supervision and transition lenses. |

Novel blends of photo-initiators and photo-absorbers are disclosed. By the proper selection of the type and amount of absorber used in a composition, it is possible to regulate the conditions under which photo-induced reactions occur. In a specific embodiment, blends of UV initiators and UV absorbers are used to control the conditions under which UV initiated polymerization occurs. |

The invention relates to optical elements whose optical properties can be repeatedly adjusted over time. Through the use of modifying compositions capable of stimulus induced polymerization coupled with a blend of stimulus absorbers and initiators, it is possible to repeatedly adjust the optical properties of the element by exposing the lens to a stimulus which exceeds the absorption capacity of the stimulus absorber. |

The invention relates to a method of customizing lenses using an external stimulus such as light. Fine-tuning of the lens to match the precise optical requirements using the same lens is also possible. The lenses are self-contained and do not require the addition or removal of significant portions of the lens to achieve customization. |

The wavefront aberrator is applicable to correct aberrations of the human eye. In one embodiment, the aberrator device comprises a pair of transparent lenses separated by a layer of curable resin comprising monomers and polymerization initiators. By controlling the extent of its curing, this monomer layer provides an adjustable index of refraction profile across the layer. Curing of the resin may be made by exposure to light, such as ultraviolet light. By controlling the extent of light exposure across the surface of the curable resin, for example, a particular and unique refractive index profile can be produced. |
