Advanced Collamer Lens Material



Collamer is a revolutionary material used exclusively in making STAAR® Surgical Company corrective lenses, including several models of the Visian ICL. Its name comes from the combination of “collagen” and “polymer”. Because it is made with collagen, Collamer is compatible with your body’s natural chemistry, and contributes to the High Definition Vision found only in the Visian ICL.


What is Collamer?

  • Collamer is a 100% pure collagen copolymer material that is  compatible with your body’s natural chemistry (often called  “biocompatibility.”) Because of this, it is “quiet in the eye,”  meaning you won’t even know it’s there!
  • Collamer is easy to implant because it unfolds gently and  predictably in the eye.
  • Collamer transmits light very similarly to your natural lens because the material’s characteristics are nearly identical to  the human crystalline lens1.



CollamerCollamer offers numerous advantages over other lens materials:

Quality of Vision

Due to its unique anti-reflective propertiesand high water content, Collamer helps transmit light nearly identically to the human crystalline lens. This means less light is reflected within the eye, leading to sharper, clearer vision; and far fewer occurrences of glare, halos, or poor night vision associated with other lenses or corrective procedures. These are the precise qualities of High Definition Visian, available only from the Visian ICL.


Meaning “compatible with your body’s natural chemistry,” biocompatibility is a key advantage of Collamer. The collagen in the Collamer attracts fibronectin, a substance found naturally in the eye. A layer of fibronectin forms around the lens, inhibiting white cell adhesion to the lens. This coating prevents the lens from being identified as a foreign object, and the lens remains unnoticed and “quiet in the eye” indefinitely. What’s more, like the collagen it contains, Collamer carries a slight negative ionic charge. Proteins in the eye also carry a negative charge. As these two negative forces meet each other along the border of the Visian ICL, the charge repulsion pushes away the proteins from the lens, naturally keeping it clean and clear.

UV Protection

Long-term exposure to UV radiation can damage the eyes; longer term or more intense exposure increase the chance of eye disorders including the development of cataracts and some retinal problems. As an added feature, the Visian ICL advanced lens material contains a UV blocker that actually prevents harmful UVA and UVB rays from entering the eye, possibly preventing the development of UV related eye disorders.


The exclusive advantages of Collamer are available only in the Visian ICL. For more information on why the Visian ICL might be the best vision correction procedure for you, contact a qualified Visian ICL surgeon or STAAR Surgical Company today.
