With Ophteis, Ophteis+ and OphteisMAX, Rayner offers a complete range of ophthalmic viscosurgical devices (OVD) made from hyaluronic acid of animal origin. The specific combination of different concentrations of HA and a high molecular weight has led to three distinct products with exemplary and complementary pseudoplastic qualities. The range manufactured in Sweden offers an optically clear OVD with no bubbles and can be stored at room temperature.
