HI56


HI56 has been specifically formulated to fulfil modern-day demands for a hydrophobic intraocular lens material that offers a unique combination of high refractive index, tensile strength and flexibility, for small incision and fast unfolding time. HI56 is a fully-moulded semi-finished negative aspheric optic: the ideal solution to low-cost/high-volume hydrophobic IOLs.

The formulation has been created to complement a unique moulding technology. The material is supplied in semi-finished format (two finished optics) by Contateq BV. This simplifies the IOL manufacturer’s production process and avoids the problems associated with cryogenic and room-temperature lathing, reducing machining time and production costs and increasing output.

We also offer a one-side finished version, which helps reduce machining times while giving the laboratory the final choice in optical design. The posterior side optic has a negatively aspheric optic and the anterior lens surface can be lathed into the manufacturer’s own design.
