摘要： PROBLEM TO BE SOLVED: To provide a mask having a transport structure capable of maintaining nutrition flow from a first corneal layer to a second corneal layer without producing a visually minus effect. SOLUTION: The mask includes: an anterior surface extended between an outer periphery portion and the center optical axis line of the mask and configured to reside adjacently to a first corneal layer; a posterior surface extended between the outer periphery portion and the central optical axis line of the mask and configured to reside adjacently to a second corneal layer; an opening portion configured to transport substantially whole incident light beams along the optical axis line; an opaque portion which surrounds at least a part of the opening portion, is substantially opaque portion extended between the outer periphery portion and the central optical axis line, and includes an inner area, an outer area, and a center area positioned between the inner area and the outer area; and a plurality of holes at least partially extended between the anterior surface and the posterior surface. In the mask, the plurality of holes are irregularly arranged in the center area of the opaque portion and not in the inner area and the outer area. COPYRIGHT: (C)2011,JPO&INPIT

摘要： Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having 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 construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye. e.g., as an implant in the anterior or posterior chamber.

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.

摘要： A mask is provided that is configured to increase the depth of focus 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 portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

摘要： A therapeutic ocular inlay assembly (2130) for treatment of one or more vision defects including a locator structure or depth marker (2126) to facilitate location of the inlay post-implant. The locator structure or marker (2126) extends at least partially outside a pupil region. The depth or layer at which the inlay (2130) is implanted can be determined by locating the depth marker (2126) without requiring incisions with the pupil region. The locator structure (2126) can be substantially invisible under casual observation, however can be provided with enhanced optical contrast characteristics under selected viewing conditions. The locator (2126) is thus unobtrusive, however can be readily located in a clinical setting, for example with artificial UV illumination. The locator (2126) can be connected to, e.g., integrally formed with, an inlay (2116) or may be a separate component provided in combination with the inlay (2116).

摘要： Disclosed are masks (34) configured to be implanted in a cornea of a patient. In one embodiment, the body of the mask has a light transmitting portion (38) , a light blocking portion disposed about the light transmitting portion, and an outer periphery surrounding the light blocking portion (36) . The mask is adapted to reside between two intracorneal layers of a cornea. In a preferred embodiment, the mask is formed from a material comprising a highly fluorinated polymeric material and an opacification agent and is resistant to degradation upon exposure to ultraviolet light. In another embodiment, the mask is formed from a material which comprises a polyanionic compound. In some embodiments, the mask includes one or more wound healing modulator compounds to aid in proper healing following implantation.
