The first GP lens material to offer the best of both worlds…
Paragon HDS® is the first and only lens material to offer all of the performance and structural characteristics of a “workhorse” lens material with surperb oxygen permeability. In developing the material, Paragon researchers utilized concepts gleaned from the NASA Space Shuttle program to engineer a proprietary Hyperpurified Delivery System (HDS) that effectively eliminated so-called “bad” silicone from the polymer. By purifying its silicone content, researchers were able to make Paragon HDS the most oxygen efficient polymer on the market today. Paragon HDS contains the highest percentage of MMA for its Dk value of any flurosilicone acrylate material currently available.
In addition to having the execellent performance characteristics of a lower Dk material, Paragon HDS (paflufocon B) is approved by the FDA for up to seven days of continuous wear. Along with this approval, Paragon HDS was the subject of the most complete and comprehensive study on GP extended wear ever completed in the industry. This National Instutute of Health sponsored study confirming safety and efficacy, entitled CLEWS I & II, was conducted over a five year period by Professor Kenneth Polse, OD at the University of California Berkeley and was published in the peer-reviewed journal, Ophthalmology, in August 2001.
