    摘要： A fracturable mask for treating presbyopia is disclosed. The fracturable mask can include an aperture for improving depth of focus. The fracturable mask can be embedded in an intraocular lens. The intraocular lens can include a lens body and the fracturable mask. The fracturable mask can be configured to fracture along a plurality of fracture pathways when the intraocular lens is manipulated. For example, fractures can be created in the mask during the process of injecting the intraocular lens through a cartridge tip into a patient's eye. The fractures can allow the resilient lens body to restore the fractured mask to its original, pre-injection optical performance specifications.

    摘要： Implantable corneal and intraocular implants such as a mask are provided. The mask can improve the vision of a patient, such as by being configured to increase the depth of focus of an eye of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a transition portion that surrounds at least a portion of the aperture. This portion can be configured to switch from one level of opacity to another level of opacity through the use of a controllably variable absorbance feature such as a switchable photochromic chromophore within a polymer matrix.

    摘要： Corneal inlays and masks and methods of improving vision of a patient with corneal inlays and masks are provided. Masks with an aperture can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. For example, a mask can have an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion, such as a clear lens or aperture. This provides an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The mask may also include nutrient transport structures that provide nutrient flow through mask to prevent nutrient depletion. These nutrient transport structures can be configured to concentrate nutrient transmission near a center region of the mask to provide more nutrient flow near the center region.
