    Abstract: A preloaded intraocular lens (IOL) system/method utilizing haptic compression is disclosed. The disclosed system/method utilizes an IOL packaged in a compressed state that is inserted into a patient using a cartridge and lumen through which the IOL is advanced. Within this context the haptics to the IOL are wrapped around the IOL in a coplanar fashion during the loading of the IOL to permit the IOL to be shipped and stored in a compressed state. This compressed state is achieve by wrapping the haptics of the IOL during the manufacturing process to ensure that the IOL is properly aligned and thus delivered in a predetermined orientation within the patient's eye. This compressed packaging of the IOL permits a more uniform and consistent placement of the IOL in the patient and eliminates the potential for physician error during the critical IOL placement procedure.

  • Patent number: 8663235
    Abstract: This invention describes a simple intraocular lens (IOL) design with a removable optic, which can be inserted in and removed from a haptic device. In this haptic the anterior and posterior capsules are sealed in order to have a perfect control over the lens epithelial cell proliferation which is thereby restricted to the peripheral part of the capsular bag. Additionally, a ring caliper is described as new surgical device to allow a precise sizing and centration of the anterior capsulorhexis. The removable optic allows repeatable correction of the eye focusing over time in case the optical parameters of the eye have changed due to a variety of factors. By separating the optic part from the haptic part, the optic part can easily be manufactured in any shape matching the optical errors of the eye, including the ocular aberrations. The optic part can be manufactured out of any biomaterial restoring ocular accommodation.

    Abstract: Apparatus and methodology for inserting an intraocular lens (IOL) into an eye. The apparatus includes a cartridge for holding an IOL and a handpiece with a body member for receiving the cartridge, an injector rod that is receivable by the body member, and a drive mechanism that longitudinally oscillates the injector rod in the body member when a rotational force is applied about a longitudinal axis in a single direction. In other words, a constant rotation in a single direction of the drive mechanism causes the injector rod to move distally and proximally in discrete increments, with the distal increments being larger than the proximal increments. Accordingly, the injector rod urges an IOL out of the handpiece in a two-steps-forward, one-step-back manner, thereby minimizing or eliminating the chance of the injector rod engaging with the IOL.

  • Patent number: 8623037
    Abstract: A system and method is disclosed for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The system and method comprises a surgical tool comprising a surgical blade for making incisions in the sclera of an eye. When a surgeon places the surgical blade on the sclera of the eye a pressure sensor in the surgical tool determines whether there is sufficient pressure between the surgical tool and the sclera of the eye for the surgical tool to operate properly. The surgeon activates the surgical tool to cause the surgical blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the surgical blade is rotated back out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

  • Publication number: 20130345713
    Abstract: A system for easily transferring an intraocular lens (IOL) from a lens case to an inserter, and then into a patient's eye. The lens case has a transfer mechanism therein which retains the IOL until engagement with the inserter. The transfer mechanism may include jaws having a closed configuration for retaining the IOL and an open configuration for releasing the IOL. Engagement of the inserter with the lens case automatically opens the jaws and transfers the IOL to the inserter. The IOL is transferred into a load chamber of a nosepiece rotatably coupled to a handpiece. After transfer of the IOL, the nosepiece is rotated from a load position to a delivery position. The IOL may have an optic and a haptic coupled to the optic, and the lens case may be capable of configuring the haptic as desired to facilitate its transfer into an inserter and/or into the eye. For instance, the lens case may fold one or both of the haptics over the optic.
