20080262610 | BIOMECHANICAL DESIGN OF INTRACORNEAL INLAYS - Provided herein are intracorneal inlays for correcting vision impairments by altering the shape of the anterior corneal surface. The physical design of the inlay to induce the desired change of the anterior corneal surface includes consideration of the biomechanical response of the corneal tissue to the physical shape of the inlay. This biomechanical response can differ depending on the thickness, diameter, and profile of the inlay. In one embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an “effect” zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the “effect” zone. In another embodiment, small diameter inlays are provided that induce “effect” zones on the anterior corneal surface that are much larger in diameter than the inlays. | 10-23-2008 |
20090076601 | Cornea Implant - Annular cornea implant for inserting into a cornea pocket of the human eye via a narrow, tunnel-shaped access, with the end shape of the cornea implant depending on the shortsightedness or astigmatism to be corrected. The aim of the invention is to enable the cornea implant to be implanted in the cornea pocket in a simple manner and in an optimum position. To this end, the implant has a shape memory which is impressed on the basis of the geometry and/or material of the implant, and is designed in such a way that the deformability from a starting shape enables the insertion of the cornea implant into the cornea pocket via the narrow access, and the cornea implant has an adjustment force in the end shape thereof, which enables an essentially independent unfolding of the cornea implant in the cornea pocket. | 03-19-2009 |

20090287306 | Optical hydrogel material with photosensitizer and method for modifying the refractive index - A method for modifying the refractive index of an optical, hydrogel polymeric material. The method comprises irradiating predetermined regions of an optical, polymeric material with a laser to form refractive structures. To facilitate the formation of the refractive structures the optical, hydrogel polymeric material comprises a photosensitizer. The presence of the photosensitizer permits one to set a scan rate to a value that is at least fifty times greater than a scan rate without the photosensitizer in the material, yet provides similar refractive structures in terms of the observed change in refractive index. Alternatively, the photosensitizer in the polymeric material permits one to set an average laser power to a value that is at least two times less than an average laser power without the photosensitizer in the material, yet provide similar refractive structures. | 11-19-2009 |
20100036488 | Therapeutic device for pain management and vision - A therapeutic lens for the treatment of an epithelial defect comprises a layer of therapeutic material disposed over the stroma and/or Bowman's membrane to inhibit water flow from the tear liquid to the stroma and/or Bowman's membrane, such that corneal deturgescence can be restored to decrease corneal swelling and light scattering. The layer may cover and protect nerve fibers to decrease pain. The layer may comprise an index of refraction to inhibit light scatter from an anterior surface of the stroma and/or Bowman's membrane. The lens may comprise a curved anterior surface that provides functional vision for the patient when the epithelium regenerates. The layer of therapeutic material can be positioned on the eye in many ways, for example with a spray that is cured to adhere the layer to the exposed surface of the stroma and/or Bowman's membrane. | 02-11-2010 |
