  • Publication number: 20090275936
    Abstract: Thermokeratoplasty is applied to achieve a customized reshaping of a cornea, especially, for the treatment of astigmatism. Energy is applied to the cornea in a customized pattern using a specific configuration of two conductors. In one embodiment, an outer conductor and an outer conductor are separated by a gap. When a conducting element is applied to the corneal surface the area of the cornea at the periphery of the inner conductor is subject to an energy pattern with substantially the same shape and dimension as the gap between the inner and outer conductors. The inner and outer conductors may be positioned and shaped to form a gap having any desirable size and/or shape, including non-annular and asymmetrical shapes.

  • Publication number: 20090209954
    Abstract: A system for applying therapy to an eye includes an applicator having a conducting element configured to direct energy from an energy source to an application end of the conducting element, where the application end has at least one eye contact portion. A positioning system positions the at least one eye contact portion in stable engagement with the eye surface. The conducting element is disposed within a housing for the applicator and at least one adjustment system is employed to move the conducting element relative to the housing. The at least one adjustment system enables controlled movement of the conducting element and the at least one eye contact portion against the corneal surface. In particular embodiments, sufficient contact between the applicator and the cornea is determined by causing applanation of the cornea. In other embodiments, at least one measurement device is employed to determine when sufficient contact has been established.

    Abstract: A system for applying therapy to an eye includes an applicator having a conducting element configured to direct energy from an energy source to an application end of the conducting element, where the application end has an eye contact portion. A positioning system receives the applicator and positions the eye contact portion in stable engagement with the surface of an eye. In some embodiments, the conducting element is disposed within a housing for the applicator and an adjustment system is employed to move the conducting element relative to the housing. The adjustment system enables controlled movement of the conducting element and the eye contact portion against the corneal surface. In particular embodiments, sufficient contact between the applicator and the cornea is determined by causing applanation of the cornea.

  • Publication number: 20090187173
    Abstract: A system for applying therapy to an eye includes an energy source and a conducting element operably connected to the energy source and configured to direct energy from the energy source to an application end of the conducting element. The application end includes an eye contact portion configured to apply the energy to an eye feature and provides a reshaping mold to reshape the eye feature as the eye feature responds to the application of the energy. The eye contact portion may have a concave curvature and may be positioned in direct contact with the eye feature. In addition, the eye feature may be the cornea of the eye. In a particular embodiment, the energy source is an electrical energy source, the conducting element comprises an outer electrode and an inner electrode separated by a gap, and the eye contact portion is positioned on the inner electrode.

  • Publication number: 20090187178
    Abstract: A system for aligning an eye therapy instrument over a selected area or feature of an eye provides an attachment element that is removably attached to a surface of an eye. A receiving element is coupled to the attachment element and movable relative to the attachment element. The receiving element includes a coupling element configured to operably couple an eye therapy instrument to the receiving element and adjustably move the eye therapy instrument into a selected position with respect to the attachment element. The system makes adjustments to ensure accurate delivery of treatment from the eye therapy device to areas of the eye. In one embodiment, the receiving element allows lateral adjustments to be made along one or more axes. Additionally or alternatively, the receiving element allows angular or rotational adjustments to be made about one or more axes.

  • Publication number: 20090149842
    Abstract: Heat is generated in corneal fibrils in a cornea of an eye according to a selected pattern. The heat causes the corneal fibrils corresponding to the selected pattern to transition from a first structure to a second structure. The second structure provides a desired reshaping of the cornea. A cross-linking agent is then activated in the region of corneal fibrils according to the selected pattern. The cross-linking agent prevents the corneal fibrils from changing from the second structure. Thus, embodiments stabilize corneal tissue and improve its biomechanical strength after desired structural changes have been achieved in the corneal tissue. Accordingly, the embodiments help to preserve the desired reshaping of the cornea.

  • Publication number: 20090069798
    Abstract: A system for applying therapy to an eye selectively applies coolant to the corneal surface to minimize heat-related damage to the corneal surface during thermokeratoplasty. Embodiments may include an energy source, a conducting element, a coolant supply, and a coolant delivery system. The conducting element is operably connected to the energy source and extends from a proximal end to a distal end.

  • Publication number: 20080044063
    Abstract: A multimodal biometric identification system captures and processes images of both the iris and the retina for biometric identification. Another multimodal ocular system captures and processes images of the iris and/or the from both eyes of a subject. Biometrics based on data provided by these systems are more accurate and robust than using biometrics that include data from only the iris or only the retina from a single eye. An exemplary embodiment emits photons to the iris and the retina of both eyes, an iris image sensor that captures an image of the iris when the iris reflects the emitted light, a retina image sensor that captures an image of the retina when the retina reflects the emitted light, and a controller that controls the iris and the retina illumination sources, where the captured image of the iris and the captured image of the retina contain biometric data.

  • Publication number: 20070286462
    Abstract: Retinal blood vessels are detected for biometric identification by: receiving at least one image with retinal data; detecting an area in the image corresponding to a spatial variation in the image; and determining a blood vessel pattern relative in the area. The spatial variation may be determined according to a spatial intensity gradient. The area corresponding to the spatial variation may be defined by a fitted shape. A specific embodiment determines a structural measurement, such as a structural center of mass, in the area, and the blood vessel pattern is determined relative to the structural measurement. The blood vessel pattern may be determined by identifying blood vessel cross sections within the area and linking the blood vessel cross sections to determine blood vessels. Furthermore, each of the blood vessel cross sections may be represented by an N-vector determined by a N-parameter non-linear fitting function or a linear function combination.

  • Publication number: 20070083155
    Abstract: Injection devices, systems and methods are disclosed for injecting two or more medicaments to a patient at a single injection site while preferably minimizing any mixing of the medicaments prior to delivery to the patient. The invention can also be used to sequentially deliver the medicaments to the patient in a repetitive manner. For example, the injection apparatus can sequentially provide a first medicament and then a second medicament to the patient during a first injection procedure. During a second injection procedure, the injection apparatus can again sequentially provide the first medicament and the second medicament to the patient either at the injection site of the first injection procedure or at a different injection site. Multi-lumen manifolds are disclosed for coupling to conventional drug ampoules, to permit the user to sequentially delivery different medicaments via a single skin penetration. Systems including multiple drug reservoirs and filling adaptors are also disclosed.
