Publication number: 20220280285Abstract: 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.Type: ApplicationFiled: May 9, 2022Publication date: September 8, 2022Inventors: Bruce A. Christie, Alexei N. Kosmynine

Patent number: 9427311Abstract: 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.Type: GrantFiled: August 13, 2010Date of Patent: August 30, 2016Assignee: AcuFocus, Inc.Inventors: Bruce Christie, Edward W.

Patent number: 9138142Abstract: An ophthalmic device that includes a mask configured to be implanted posterior of the cornea. The mask is configured to increase the depth of focus of the patient. The mask includes an aperture configured to transmit along an optical axis substantially all incident light and a substantially opaque portion surrounding at least a portion of the aperture. The ophthalmic device can further include a plurality of light transmission structures configured to allow some light to pass through the substantially opaque portion. The light transmission structures are configured to minimize generation of visible artifacts due to the transmission of light through the light transmission structures.Type: GrantFiled: May 3, 2006Date of Patent: September 22, 2015Assignee: AcuFocus, Inc.Inventors: Bruce A.

Patent number: 8864824Abstract: A method is provided for increasing the depth of focus of an eye of a patient. A visual axis of the eye is aligned with an instrument axis of an ophthalmic instrument. The ophthalmic instrument has an aperture through which the patient may look along the instrument axis. A first reference target is imaged on the instrument axis at a first distance with respect to the eye. A second reference target is imaged on the instrument axis with the ophthalmic instrument at a second distance with respect to the eye. The second distance is greater than the first distance. Movement is provided such that the patient's eye is in a position where the images of the first and second reference targets appear to the patient's eye to be aligned. A mask comprising a pin-hole aperture having a mask axis is aligned with the instrument axis such that the mask axis and the instrument axis are substantially collinear.Type: GrantFiled: May 3, 2006Date of Patent: October 21, 2014Assignee: AcuFocus, Inc.Inventors: Thomas A.
