  • Publication number: 20160262933
    Abstract: Patterned laser treatment of the retina is provided. A visible alignment pattern having at least two separated spots is projected onto the retina. By triggering a laser subsystem, doses of laser energy are automatically provided to at least two treatment locations coincident with the alignment spots. All of the doses of laser energy may be delivered in less than about 1 second, which is a typical eye fixation time. A scanner can be used to sequentially move an alignment beam from spot to spot on the retina and to move a treatment laser beam from location to location on the retina.

  • Publication number: 20160213243
    Abstract: A visual function evaluation is performed using a sequence of interactions with a mobile device. A patient user may perform a variety of visual tests using the mobile device. The mobile device transmits the test results to a remote server implementing analysis of the visual function results using network service. The network service receives the test results, processes the results, and provides the processed results to a healthcare provider. The processed results may include trends of the user's visual function test performance. The healthcare provider, such as a physician, may optimize and administer treatment based on the data. Early detection of changes in visual function can enable the healthcare provider to individualize treatment, helping to prevent vision loss while minimizing visits to the office, discomfort, and expense.

  • Patent number: 9364317
    Abstract: An intraocular lens assembly for positioning in a lens capsule of a patient's eye is disclosed. The intraocular lens is placed within an enclosed incision in target tissue in the patient's eye, wherein the incision is formed by a laser system including a scanner for deflecting a light beam to form an enclosed treatment pattern including a registration feature in the target tissue, and wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

  • Publication number: 20160113489
    Abstract: A modular lens adapter system or kit is provided for mobile anterior and posterior segment ophthalmoscopy. Equipped with various lens adapter modules, respective lenses and a mobile imaging device, a user is provided with tools for various mobile ophthalmoscopy imaging applications. Eye care practitioners can use their existing lenses to customize the modular lens adapter system in a cost-effective way, which allows for mobile and remote capture, viewing, and utilization of clinical images. The various modules are also adaptable to nearly any type of phone or tablet regardless of its dimensions or presence of a protective case. The invention also addresses the need for fewer, smaller, less expensive, and easier to use ophthalmic imaging equipment, which is further important in enabling a broad base of users.

  • Publication number: 20150366551
    Abstract: Patient-supported ophthalmic platforms for use in ophthalmic procedures are described. The platform is supported at least in part upon a patient's face where the platform is configured to cover at least one or both eyes and further includes a conformable portion which rests upon a remainder of the patient's face. The platform may also integrate rests for the hands of the surgeon and may optionally integrate an instrument rest for allowing ready access of one or more surgical instruments to the surgeon. One or more corresponding eyelid speculums may also be integrated with the surgical platform eliminating the need for a separate speculum. An irrigation fluid trough may also be integrated with the surgical platform for collecting and diverting an irrigating fluid and the platform may optionally be used in combination with an oxygen delivery mask or nasal cannula.

  • Publication number: 20140066703
    Abstract: Embodiments of the invention are directed to minimally invasive surgical instruments and procedures using those instruments wherein the instruments include optical elements (e.g. a percutaneous optical channel (POC), a retaining plug and a stereoscopic imaging device (e.g. a stereoscopic camera) and a stereoscopic display device. The instruments be part of a system used to provide a surgeon with an indirect stereoscopic view of a surgical area undergoing a minimally invasive surgical procedure in a way that is perceived by the surgeon as being similar to that of an open surgery and providing a natural and intuitive environment to perform the surgery with a high degree of control.

  • Patent number: 8101169
    Abstract: The present invention provides a method of treating an ocular disease in a subject. In a first step, a nucleic acid is introduced into cells or a tissue. The nucleic acid is introduced by electron avalanche transfection. With this technique, a high electric field induces a vapor bubble and plasma discharge between an electrode and the surrounding medium. The formation of a vapor bubble generates mechanical stress. Plasma discharge through the ionized vapor in the bubble enables connectivity between the electrode and the surrounding medium, so that mechanical stress and electric field are applied simultaneously, which results in permeabilization of the cells or tissue. This permeabilization in turn allows the nucleic acid to enter the cell or tissue. Cells or tissue containing the nucleic acid are then transplanted into an ocular region of the subject.
