Ferrara rings (FR) are intrastromal segments implanted into patient's cornea tissue. FR is composed of two 5mm-diameter semicircular segments with variable thicknesses ranged from 0,15 mm to 0,35 mm. The ring is made of Perspex CQ Acrylic, which is the same material used for more than 20 years in manufacturing intraocular lenses. The ring is perfectly tolerated by the organism and there is no risk of rejection. First FR for keratoconic patient were implanted in 1996.
