There is nothing more maddening as a specialty contact lens practitioner than being 100% certain that the fit and Rx are correct and watching the patient fail because the lens surface clouds faster than a bathroom mirror. For years we have modified cleaning protocols in the hopes that there existed a magic elixir that would somehow give patients sufficient wear time. Results were usually mediocre at best. Because necessity is the mother of all innovation, Tangible Science set out to find a solution. The result is Tangible Hydra-PEG, a revolutionary lens treatment which increases lubricity, resists lens deposits and has significantly improved patient comfort.

What is it?

Tangible Hydra-PEG is not another version of plasma treatment. While plasma treatments modify the existing lens surface, Tangible Hydra-PEG encapsulates the lens to form a permanent bond with the lens surface. The treatment is designed to be permanent but the exact lifespan of the treatment is still being studied.

Does it work?

Anecdotally I can report that over 98% of my specialty contact lens patients have preferred their Tangible Hydra-PEG treated lens over their previous lens. Various studies are still ongoing but benchtop tests thus far have shown that Tangible Hydra-PEG increased wettability, water break-up time, and lubricity.

Are there any special care instructions?

The coating can be damaged through the use of alcohol-based solutions, abrasive solutions, and tap water. Tangible Science recommends Unique pH (Menicon Co. Ltd.) or the Clear Care family of solutions (Alcon Laboratories, Inc.).

Where can I get it?

The Tangible Hydra-PEG surface treatment is available at a wide range of independent laboratories. At the time of this writing, it can be applied to material produced by Contomac (Optimum family of materials) or to hybrid contact lenses (manufactured by SynergEyes, Inc.). Ask your laboratory consultant if the treatment is available on your specialty lens of choice.

In conclusion, the Tangible Hydra-PEG treatment has produced remarkable results in regards to improving patient comfort and lens tolerability. It is yet another tool available to the practitioner that will improve outcomes and bring success to a challenging pool of patients.
