VISCO DYE

摘要

There is disclosed a composition or kit for use in so−called viscodye enhanced ocular surgery, i.e. cataract surgery. The composition comprises a first viscoelastic substance containing a visualising agent (viscodye) used for staining the capsule of the crystalline lens prior to a Continious Curvilinear Capsulorhexis (CCC). A kit contains in addition a second clear viscoelastic agent for protection and expansion. The viscosity of the viscodye secures safe and precise application within the eye and the visualising agent can be used in such low concentrations, that the surgeon is allowed to see and work through it.The viscoelastic substance preferably comprises at least one of methylene hydroxypropylene cellulose, sodium hyaluronate, and sodium chondroitinsulfatesodium hyaluronate. The visualizing agent may be chosen from e.g. azophlozin, basic blue, Bismarck brown, basis red, Bengal red, brilliant cresyl blue,eosin, fluorescein, gentian violet, indocyanine green, Janus green, methylene green, methylene blue, neutral red and trypan blue.
