Riyan 3 Piece Hydrophobic Acrylic
The clearest hydrophobic acrylic is Riyan-3 Piece. Among all the foldable IOLs tested, this one had the clearest vacuole-free material. For long-term centration and refractive stability, its Riyan-3 Piece construction is steady. The square posterior border of the Riyan-3 Piece IOL offers a constant 360-degree capsular contact while reducing glare. An incision as small as 2.8 mm can be used to deliver the Riyan-3 Piece IOL using the Riyan Jet(TM) implanatation technology.

Riyan-ED Focus - Hydrophobic Acrylic EDOF-IOL
The extended depth of Focus IOL (EDOF IOL) IOL is single, contiguous, elongated focal point that enhances depth of focus. The extended depth of focus IOL (EDOF IOL) Extended Range of Vision, is a new technology that has recently emerged in the treatment of Presbyopia-correcting IOLs. It is based on the principle of creating a single elongated focal point to enhance the “Range of Vision” or “Depth” of Focus”.
