  • Treatment liquid for reapplying (unfolding) detached retina to the chorioid of the eye
    Patent number: 5397805
    Abstract: A treatment liquid for unfolding detached retina to the chorioid of the eye containing a PFC-mixture whose PFCs are free from C.dbd.C-double bonds and C--H-bonds, with a reduced vapor pressure and a refractive index by virtue of which the PFC/tissue fluid interface is made visible.

  • Diluent for perfluorocarbons employed for retinal unfolding (unfolding PFCL) and method of treatment
    Patent number: 5244924
    Abstract: A diluent for perfluorocarbons used for retinal unfolding (unfolding PFCL), consisting of a perfluorocarbon (diluent PFCL), which has a low viscosity and is volatile at room temperature, with a boiling point between body temperature (about 38.degree. C.) and 100.degree. C., for removing residual quantities of unfolding PFCL from the eye after performance of a retinal unfolding treatment. A method of treatment consisting of introducing into an eye the above diluent for the above purpose.

  • Intraocular posterior chamber lens
    Patent number: 5015254
    Abstract: Intraocular posterior chamber lens for implantation in the capsular sack of the human eye, in which fixation loops which extend semicircularly are atttached to a circular lens body so as to form a single piece with the lens body, the outer circumference of which fixation loops are designed to accomodate the equator of the capsular sack, thereby assuring a stress-free implantation despite radial stretching of the haptic.
