ABSTRACT:
A high resolution video camera is equipped with a multi focal lens. The optical system is adjusted to provide a depth of field so that objects remain in focus. A high resolution, large screen color video monitor provides a greatly magnified view of the surgical field, permitting a surgeon to perform procedures directly from the screen image. Low light levels can be permitted and multiple monitors can be employed. Images can be stored on a disc or VCR and individual frames can be printed for a permanent record.
