Abstract: A slide for an eye drop dispenser. The slide, which may be secured to a container, is formed with a longitudinally extending channel and a distal end configured to rest against the lower eyelid of an individual during administration of a drop to the eye. The dispensed drop rolls along the channel and into the eye.

Abstract: A method and apparatus are provided for removing tissue, such as cataractous lens tissue, using ultrasonic energy. The apparatus includes a working tip and a transducer or the like for applying ultrasonic vibrations to the working tip. A vacuum source is provided for aspirating fluid through the working tip. The working tip includes a relatively large diameter opening for admitting relatively large tissue fragments. The opening adjoins a bore portion of relatively large diameter. The working tip further includes a bore portion of relatively small diameter and large wall thickness for breaking the tissue fragments into smaller pieces.

Abstract: A method of controlling astigmatism during eye surgery is provided which includes forming a wave-like incision prior to conducting surgery. Once the surgery has been completed, the wave-like incision may be stitched in a direction which is substantially parallel to the lengthwise direction of incision to avoid generating a force upon the cornea, which would tend to induce astigmatism. Astigmatism can be induced by stitching in a direction which tends to displace the tissue on opposite sides of the incision by a selected distance. Indicator lines may be applied with a sterile dye prior to surgery to allow the surgeon to insure that the tissue is not displaced when the incision is closed, or is displaced by a selected distance as may be determined by viewing the indicator lines. A marking tool is provided for marking both a wave-like outline which is used for making the incision and the indicator lines for determining relative tissue displacement.

Abstract: A surgical knife assembly is provided which includes a depth guard for limiting the depth of insertion of a cutting blade. The depth guard is constructed to allow a surgeon to view an incision as it is being made. It includes a pair of parallel ski members which define a slot therebetween. A knife blade extends through the slot and includes a cutting edge projecting beyond the respective bottom ends of the ski members. One ski member includes a front edge which allows the front edge of the knife blade to be viewed as an incision is made, while the other ski member extends beyond the front edge of the knife blade to provide stability.

Abstract: A method is provided for preventing damage to tissue during microsurgery. The method involves the use of a heat sink in the form of a cylindrical shield which is inserted within an incision prior to the use of an ultrasonic cutting tool. The heat generated by the cutting tool is absorbed by the shield rather than the surrounding tissue, thereby minimizing or eliminating damage to the tissue adjacent the cutting tool. The incision through which the cutting tool extends during an operation accordingly tends to remain in its original state rather than widening due to the effects of heat damage.

Abstract: A method and apparatus are provided for removing gelatinous tissue, such as cataractous lens tissue, from a patient. A probe-like instrument is provided which includes a thin, perforated plate mounted to an end thereof. A rotatable cutting tool is positioned within the probe and includes a cutting edge which bears against the perforated plate. The plate is moved into contact with a tissue mass, thereby causing portions of the tissue mass to project through the perforations in the plate. Rotation of the cutting tool causes the tissue mass to be sheared into small fragments which can be removed by aspiration.

Abstract: An ocular massage device comprising a rigid curved plate to rest upon the forehead and cheek and overlie the eye of the patient. An inflatable member between the plate and the patient's eyelid. An inlet tube to admit fluid under the pressure into the inflatable member, an outlet tube to permit fluid to leave the inflatable member, a check valve on the outlet tube to release fluid exceeding a desired pressure from the inflatable member and a second inflatable member to receive fluid from the check valve.
