  • Publication number: 20120209051
    Abstract: Delivery systems and methods for delivering riboflavin (R/F) and UVA irradiation to the sclera are disclosed. The R/F is delivered and then activated with UVA irradiation through the use of LEDs or optical fibers, thereby causing cross-linking of the collagen tissue. Delivery systems include implantable structures which provide surfaces that conform to the sclera. The delivery systems include various types of structures for delivery of R/F onto the sclera surface. Additionally, the delivery systems include UVA sources which provide irradiation of R/F in sclera collagen tissue.

  • Publication number: 20110178512
    Abstract: System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

  • Publication number: 20100256615
    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: 20100103103
    Abstract: A device and method for manual input of information into computing device using a camera and visible touch sensors. An image of a virtual input device is displayed on a screen, and the positions of the visible touch sensors, recorded by the video camera, are overlaid on the image of the virtual input device, thus allowing the user to see the placement of the touch sensors relative to the keys or buttons on the virtual input device. The touch sensors change their appearance upon contact with a surface, and the camera records their position at the moment of change. This way information about the position of intended touch is recorded. Touch sensors can be binary (ON-OFF) or may have a graded response reflecting the extent of displacement or pressure of the touch sensor relative to the surface of contact.

  • Publication number: 20020025298
    Abstract: The use of texaphyrins for ocular diagnosis and therapy is provided, especially use of photosensitive texaphyrins for photodynamic therapy of conditions of the eye characterized by abnormal vasculature, such as macular degeneration, or pterygium, for example. The photosensitive texaphyrin may be a free-base texaphyrin or may be metallated with a diamagnetic metal. Preferably, the photosensitive texaphyrin is metallated with lutetium. Due to the dual wavelength absorption of texaphyrins, i.e., at 400-500 nm and at 700-800 nm, especially about 732 nm, as compared to porphyrins, texaphyrins are more effective and versatile for use in humans as compared to porphyrins. Texaphyrins serve as effective contrast agents in ocular angiography.
