Abstract
An instrument to be used during ocular surgery for the rapid closure of anterior segment openings and the control of expulsive choroidal hemorrhage and the resulting damage caused by this complication. The instrument is to be positioned over the anterior ocular surface of the eye at the first indication of hemorrhage or "posterior pressure". One or more dimples located on the upper surface of the instrument allows the insertion of a elongated member for holding the instrument in place while maintaining the intraocular pressure. An opening is also present which allows a surgeon to insert sutures into the underlying eye while the instrument is in place and also aids in the movement of the instrument about the anterior ocular surface of the eye by insertion of a probe or forceps. The instrument is transparent, allowing the surgeon to visually monitor the intraocular events.
