PARIS — A noncontact
illumination system used at the University of Lausanne,
Switzerland, provides good visualization while leaving one hand free and
eliminating the need for an assistant during retinal surgery, according to a
Illumination is provided by a slit lamp, which directs the light toward
a 90 D lens, fixated with an angulated arm to the operating table and suspended
over the patient's eye.
"This simple system provides panoramic viewing of the ocular fundus
during the entire procedure, allowing the surgeon to operate on the retina and
at the same time perform peripheral indentation in a completely self-sufficient
manner. The hand that normally holds the endoilluminator remains free and can
be used for surgical maneuvers," Jean-Antoine Pournaras, MD, said at the
meeting of the
French Society of Ophthalmology.
In a study of 61 pseudophakic patients undergoing
retinal detachment surgery, external illumination was used in
conjunction with 23-gauge vitrectomy. All procedures were successfully
performed by the surgeon alone. Visualization was good at all stages and
surgical time decreased.
