Abstract: A method of correcting aberrations in an optical system by applying a light adjustable aberration conjugator layer to a component of the system, determining the nature of the aberration, applying radiation to the conjugator layer such as to change the refraction and/or shape of the conjugator layer to compensate for the aberration, and locking in the desired optical property.

Abstract: 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.

Abstract: The invention relates to a novel method for preparing materials whose properties can be manipulated after fabrication.

The method is particularly useful in the manufacture of light adjustable optical elements such as intraocular lenses.

Abstract: The invention relates to a multi-lens intraoccular lens system having an accommodation material between the lenses. The system comprises an posterior lens attached to the posterior surface of the capsular bag and an anterior lens attached to the anterior surface of the capsular bag. The anterior and posterior lenses have different optical properties providing different degrees and types of correction. An accommodation material is placed between the anterior and posterior lenses. The accommodation material ma comprise of one or more macromers, which, when polymerized, adjust the properties of the accommodation material.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a novel composition for improving the accommodation capability of an intraocular lens (IOL). In one embodiment, the composition can be injected into the capsular bag where it surrounds an implanted IOL anchoring the IOL to the capsular bag. Alternatively, for anterior chamber IOLs, the composition can be injected into the bag behind the lens. The material has a refractive index similar to that of aqueous thereby reducing any potential interference with the implanted IOL. Accommodation is provided by the mixture of the crosslinked composition caused by the flexing of the muscles. The novel composition is particularly useful in enhancing accommodation for adjustable intraocular lenses.
