i- stream HF+

  • One-piece monofocal plus lens with hydrophilic / hydrophobic copolymer preloaded in kit with Medicel injector, with biconvex surface with negative asphericity. Quadrilateral shape with fenestrated haptics.

 

  • Monofocal Plus lenses represent a breakthrough in the world of single-vision lenses. While until now, patients with a monofocal lens implant could only focus on one depth of field, istream hf+ now offers superior visual performance, thanks to the ability to see up to medium distances.

 

  • Monofocal Plus intraocular lenses are designed to provide even intermediate-distance vision with unprecedented clarity, even at medium distances up to a distance of approximately 66 cm.
