Abstract: Embodiments of the present invention relate to an electro-active element having a dynamic aperture. The electro-active element provides increased depth of field and may be used in a non-focusing ophthalmic device that that is spaced apart from but in optical communication with an intraocular lens, a corneal inlay, a corneal onlay, a contact lens, or a spectacle lens that provide an optical power. The electro-active element provides increased depth of field and may also be used in a focusing or non-focusing device such as an intraocular optic, an intraocular lens, a corneal inlay, a corneal onlay, or a contact lens which may or may not have an optical power. By changing the diameter of dynamic aperture either increased depth of field or increased light reaching the retina may be achieved.

Abstract: A device and/or apparatus that comprises a dynamic optical lens is provided. A first apparatus includes a first lens component having a first surface and a second surface. The first apparatus further includes a second lens component that comprises a flexible element. The first apparatus also includes a fluid that may be applied between at least a portion of the first lens component and at least a portion of the second lens component. The flexible element of the second lens component is such that it conforms to the first surface of the first lens component when an amount of fluid between the first surface of the first lens component and the second lens component is sufficiently low. The flexible element of the second lens component is also such that it does not conform to the first surface of the first lens component when an amount of fluid between the first surface of the first lens component and the second lens component is sufficiently great.

Abstract: A lens system is presented having a lens having an electro-active element, a sensor for sensing a change in ambient light, a controller in operative communication with the sensor, and a plurality of electrode rings electrically connected to the controller. The electrode rings may be concentric. The controller applies a voltage to the plurality of electrode rings when the sensor senses a change in ambient light. The application of voltage causes a change in the refractive index of the electro-active element for correcting a spherical aberration of the eye due to the sensed change in ambient light.

Abstract: A method of closing an incision includes inserting a catheter (32) and the first and second balloons (50, 58) through an introducer (48) to have the first balloon (50) located in the artery (24). Next, the catheter (32) and the first balloon (50), which has been inflated, are withdrawn to apply a first force (F1) to the puncture hole (22) and close the puncture hole (22). The method is distinguished by injecting a clotting agent (60) into a second balloon (58) to inflate the second balloon (58) and to create a cavity between the insertion hole (68) and the puncture hole (22). The slit (62) in the second balloon (58) expands into an open position as a result of a pressure (P) within the second balloon (58) to eject the clotting agent (60) therefrom. Next, the first balloon (50) is deflated, and the catheter (32) and the first and second balloons (50, 58) are removed from the insertion hole (68). Finally, a second force (F2) is applied to the insertion hole (68) to stop the flow of blood.

Abstract: An integrated wavefront sensor and adaptive optic system includes an electroactive lens (40) positioned such that light from real world objects (42) being observed by a patient is combined, by a combiner optic (44), with a wavefront sensor illumination beam (12) into a single beam of light (46) that passes through or onto the electroactive lens (40). With this integrated system, the patient's vision may be measured and corrected, taking into account changes in the higher order aberrations that are influenced by the patient's accommodation, simultaneous to the patient observing, in real time, the refractive correction being proposed.

Abstract: An arterial closure device (20) comprises a body (26) having first and second ports (28, 30) and a catheter (32) having proximal and distal ends (34, 36) extending from the body (26). The catheter (32) defines first and second lumens (38, 40) in operative communication with the first and second ports (28, 30). A first balloon (50) is positioned adjacent the distal end (36) of the catheter (32) and is operatively coupled to the first lumen (38) to receive a fluid through the first port (28) to expand the first balloon (50). A second balloon (58) is operatively coupled to the second lumen (40) to receive a clotting agent (60) through the second port (30) to inflate the second balloon (58). At least one slit (62) is disposed in the second balloon (58) and the slit (62) is expandable between open and closed positions in response to inflation of the second balloon (58) such that the clotting agent (60) is ejected through the slit (62) in the open position to close the puncture hole (22).

Abstract: A wavefront measuring system and method for detecting aberrations in wavefronts that are reflected from, transmitted through, or internally reflected within objects sought to be measured, e.g., optics systems such as the human eye. The system includes one or more reticles in the path of a return wavefront from the object, and a detector at a diffraction pattern self-imaging plane relative to the reticle(s). A diffraction pattern of the wavefront is analyzed and results in a model of the wavefront phase characteristics. A set of known polynomials may be fitted to the wavefront phase gradient to obtain polynomial coefficients that describe aberrations in the object, or within the wavefront source being measured.

Abstract: A wavefront sensor is integrated with a surgical microscope for allowing a doctor to make repeated wavefront measurements of a patient's eye while the patient remains on an operating table in the surgical position. The device includes a wavefront sensor optically aligned with a surgical microscope such that their fields of view at least partially overlap. The inclusion of lightweight, compact diffractive optical components in the wavefront sensor allows the integrated device to be supported on a balancing mechanism above a patient's head during a surgical procedure. As a result, the need to reposition the device and/or the patient between measuring optical properties of the eye and performing surgical procedures on the eye is eliminated. Many surgical procedures may be improved or enhanced using the integrated device, including but not limited to cataract surgery, Conductive Keratoplasty, Lasik surgery, and corneal corrective surgery.
