  • Dilation enhancer
    Patent number: 6101411
    Abstract: A contact lens with a conductive outer shell (one electrode of a two-electrode electrophoresis device) and a preferably soft, preferably disposable contact lens for contacting a patient's eye, assists in delivering dilation drops or other medicaments to a patient's eye. Advantageously, the lens is used with a relatively small hand-held power source. Electrophoresis can be used to help deliver dilation drops more rapidly, regardless of the delivery apparatus used for the electrophoresis.
