The Roto-Extractor, designed by Nicholas Douvas, M.D., was used by the authors in 66 eyes for cataracts, secondary membranes, and persistent hyperplastic primary vitreous. The average age of the patients with congenital cataracts was 2.4 years, for traumatic cataracts 16.4 years. The pupil wal cleared well in 63 of these eyes. There was no vitreous to the wound in any of the eyes. Unplanned iridectomies and prolonged inflammation were the major complications.
