In 1949 British surgeon Sir Harold Ridley asked Rayner to design and produce the first IOL. Since this pioneering work in the restoration of sight, Rayner has worked with surgeons around the world in the continued development of the IOL.
More than sixty years later, Rayner’s Rayacryl® C-flex® lenses are minimally invasive implants which, when injected into the eye, bring immediate restoration of sight. In addition to the regular-size monofocal lenses (C-flex®) there is the larger sized lens (Superflex®), the toric lens for correcting pre-existing astigmatism (T-flex®).
I-MED Surgical is the exclusive distributor for Rayner in Canada and the Carribean.
