Abstract: A toric intraocular lens is provided to eliminate or substantially reduce the expected postoperative astigmatism induced by eye surgery. The lens is constructed such that the finally placed vertical meridian is optically weaker than the horizontal meridian. The lens is constructed to ensure that the vertical meridian will be properly aligned when placed in the eye, such as by disposing the haptics along the vertical meridian.

Abstract: A cam-guided trephine for selectively cutting a portion of an eye provides a first, vertically disposed blade to provide an annular cut of essentially any practical shape, diameter and depth, while concurrently allowing a second, angled blade, to simultaneously provide a circular cut of substantially any practical angle, diameter, and depth. Each of the blades may be individually controlled by the surgeon, alternately and progressively lowered onto the eye during series of rotations.

Abstract: A method of manufacturing support garments for human extremities, and the garments so produced. A support garment form is cut from a sheet of warp-knit power fabric, the fabric having a lengthwise (machine) dimension of greatest stretch and power, and a filling dimension (the cross-machine direction) in which the stretch is incidental (i.e., about 250%/80% or at least 2/1) and the sheet being orientated during cutting so that the lengthwise dimension of the sheet extends circumferentially in the final garment produced. The edges of the garment formed are seamed to produce the final support garment, the seam extending along the dimension of elongation of the extremity on which the support garment fits.

Abstract: A surgical knife which is particularly adapted to achieve a more precise incision for cataract extractin includes a handle having at one end cutting means in the form of a projecting planar shoe member which is spaced from a pair of projecting ski members, and wherein the cutting blade is disposed perpendicular to the plane of the shoe member, and extends from said shoe member to the space between the ski members. In use, during a cataract operation, the shoe is introduced in the angle created by the iris and the cornea, and is operative to prevent the cutting means or razor blade which is attached perpendicularly to the shoe from encountering the iris and the lens. The spaced skis are positioned outside the eye so as to act as a guide and prevent the surgeon from inadvertently pushing the shoe into the iris or the lens.
