Abstract: An intraocular lens which is compressible to fit through a small ocular incision into the eye and whose refractive power is adjustable once the inserted lens has been reformed and remedially positioned in the eye. The lens includes a deformable soft optic, a translucent collar encircling the soft optic and attached to it at fixed spaced points, and haptics attached to the collar for remedially positioning the soft optic in the eye. The collar has a separation or break to define two collar arms. When the collar is compressed the arms slide relative to one another to narrow the collar, and the compressed lens can then be inserted in the eye. Once in the eye the collar is released and the arms reformed together to form a rigid circle supporting the soft optic. The soft optic is formed by a transparent bag having a thickened perimeter and filled with a transparent fluid. When the lens is in place in the eye, a fine needle can be inserted into the eye and into the bag perimeter.

Abstract: A corneal vacuum trephine system including a suction ring having an annular suction ring surface configured to define a suction annular space positionable against the eye. A vacuum device creates a vacuum in the suction annular space to secure the suction ring to the eye over the cornea. A trephine having a cutting edge is positionable so as to be movable relative to the suction ring for making with its cutting edge a circular cut in the cornea. A trephine guide is positionable on the suction ring for subsequently guiding the trephine therethrough and relative to the cornea. The guide permits the trephine to be separated from the suction ring after cutting the cornea when the suction ring is secured to the eye so that the cut in the cornea can be examined and the trephine positioned again in the suction ring precisely in the same place and orientation in the incomplete cornea cut to deepen the cut.
