What is Heparin Surface Modification (HSM)?
The latest development in veterinary intraocular lens (IOL) technology is the heparin surface modification (HSM) of lenses by I-MED. This is an important advance in veterinary ophthalmic technology—and another step into the future of implant surgery by I-MED. Heparin is a carbohydrate molecule endogenous to invertebrates and mammals. It is not recognized as a foreign substance by the body, and does not appear to elicit immunologic reactions. In addition, heparin surface modification has been tested on various implantable devices for the purpose of reducing bacterial adhesion and thereby reducing the risk of infection. Referenced articles in scientific literature that elaborate on the benefits of heparin coating are available upon request. The patented heparin surface modification of treated intraocular lenses provides a strong molecular attachment between the heparin and the polymer lens surface. Only sterile, medical grade heparin, which is fully tested in accordance with US Pharmacop
