A modified Flieringa-Legrand ring for use in trabeculectomy

The Flieringa-Legrand ring has been modified for use in trabeculectomy. It may be used with the Forbes scleral support system, which is designed to prevent posterior infolding of the sclera. This combination is particularly suited for filtration surgery on infantile and juvenile glaucoma and in high myopia, where vitreous loss is a potential threat.
