A new endoillumination infusion cannula for pars plana vitrectomy.

A new endoillumination infusion cannula has been developed that allows for wide field illumination of the retina during pars plana vitrectomy surgery. This frees the surgeon from having to use one of the intravitreal probes for endoillumination when using the bimanual technique in pars plana vitrectomy. This innovative endoillumination source also can be used with indirect ophthalmoscopy, at surgery, avoiding the glare generated by the indirect ophthalmoscope's light beam interacting with the corneal surface and the condensing lens surfaces.
