  • Publication number: 20150144514
    Abstract: The disclosure herein provides ophthalmic surgical systems, methods, and devices. In one embodiment, a surgical apparatus for use by a surgeon during a surgical procedure comprises one or more sealed sterilized surgical packs configured to be disposed of after a single or a limited number of surgical procedures, the one or more sealed sterilized surgical packs comprising: a sterile surgical instrument; and a sterile surgical tray comprising a top surface configured to be part of a sterile field of the surgical procedure, the top surface comprising a receiving structure for positioning therein of the sterile surgical instrument, the sterile surgical tray further comprising walls that define a recess sized and configured to receive a reusable non-sterile module, the recess configured to encapsulate the reusable non-sterile module to isolate the reusable non-sterile module from the sterile field of the surgical procedure.

  • Publication number: 20150147810
    Abstract: Thin parylene C membranes having smooth front sides and ultrathin regions (e.g., 0.01 ?m to 5 ?m thick) interspersed with thicker regions are disclosed. The back sides of the membranes can be rough compared with the smooth front sides. The membranes can be used in vitro to grow monolayers of cells in a laboratory or in vivo as surgically implantable growth layers, such as to replace the Bruch's membrane in the eye. The thin regions of parylene are semipermeable to allow for proteins in serum to pass through, and the thick regions give mechanical support for handling by a surgeon. The smooth front side allows for monolayer cell growth, and the rough back side helps prevents cells from attaching there.

  • Publication number: 20140365235
    Abstract: A personal surgical center embodied as a general purpose computer (e.g. laptop) with wireless technology for monitoring the operation of an independent surgical center and/or handheld instruments. The computer tracks procedures in the operating room and instruments used during those procedures, and accounts for billing, supply management, and payment options. The monitoring of the instruments used during the surgery is conducted by the personal surgical center while actual control of the settings of those instruments is via the independent surgical center or via controls included in the instruments themselves. The monitored information is stored in a log file which is then transmitted to a hospital server for generating reports, inventory control, billing, and the like. Other information generated during the procedure (e.g. doctor notes) is also stored in the log file.

  • Publication number: 20140243712
    Abstract: Systems and methods are described providing for the use of ultrasound energy to effect the dislodging of one or more blood clots inside blood vessels. Such clots can include those inside retinal vessels, especially in patients with central retinal vein occlusion. Embodiments of the present disclosure may be used for any retinal arterial or venous occlusion. In exemplary embodiments, a small probe can be inserted into the eye of a patient and placed over the retinal vessels. Acoustic streaming created by the probe can be directed to an area or region including targeted blood vessels, resulting in increased flow in one or more retinal veins and facilitating or effecting mechanical dislodging of one or more blood clots in the targets blood vessels. Exemplary embodiments can utilize ultrasonic energy produced at a frequency of approximately 44 MHz to 46 MHz with pulse repetition frequencies of approximately 100 Hz to 100 kHz.

  • Publication number: 20140227437
    Abstract: Systems, devices, and methods are presented for a prosthetic injectable intraocular lens. The lenses can be made from silicone, fluorosilicone, and phenyl substituted silicone and be semipermeable to air. One or more silicone elastomeric patches located outside the optical path on the anterior side but away from the equator can be accessed by surgical needles in order to fill or adjust optically clear fluid within the lens. The fluid can be adjusted in order to set a base dioptric power of the lens and otherwise adjust a lens after its initial insertion. The elastomeric patches are sized so that they self-seal after a needle is withdrawn. A straight or stepped slit in the patch can allow a blunt needle to more easily access the interior of the lens.
