Abstract
Abstract A disposable fiber optic sleeve for attachment at the forefront of a surgical instrument. The sleeve is an elongated tubular shape and incorporates multiple fiber optic bundles for transmission of visible light to enhance intraocular visualization. Additional bundles of optical fibers may provide for the application of laser beam and video transmission to intraocular tissue. The sleeve is constructed of inexpensive plastic materials and is designed to be disposable after a single or several uses.
