If a patient uses SupraClens only or rubs it directly on a soft lens, the lens will temporarily change parameters, says Ralph Stone, Ph.D., a senior director at Alcon. Storage of the lens in Opti-Free Express or Opti-One will re-equilibrate it.

Studies show that Alcon's Opti-Free® Express® No RubTM Multi-Purpose Disinfecting Solution kills acanthamoeba in both the trophazoite and cyst form when lenses are stored in the solution for six hours or longer 1,2 , said Ralph Stone, Ph.D., vice president, Lens Care Research and Develop-ment at Alcon.Acanthamoeba eye infections are rare, but potentially serious and could lead to vision impairment.
An article in the British Journal of Ophthalmology February 2002 issue questioned the ability of some contact lens solutions to keep lenses safe from acanthamoeba.However, Opti-Free Ex-press No Rub was not included in the study.
"Opti-Free Express No Rub proprietary disinfecting formula - Polyquad® (polyquaternium-1)and Aldox® (myristamidopropyl dimethylamine) is different from the multi-purpose solution tested," explained Dr. Stone."Polyquad and Aldox kill acanthamoeba during the soak."Studies showing this have been published in the July 2000 issue of Contact Lens Association of Ophthal-mology Journal and in the 1998 edition of Contact Lens and Anterior Eye, a British journal.Opti-Free Express No Rub MPDS is widely available at retail stores.
The British Journal of Ophthalmology article authors tested the ability of two hydrogen peroxide-based care systems and one multipurpose solution to kill the microbe.The hydrogen peroxide systems tested required eight hours of soaking in un-neutralized solution to kill the acanthamoeba, which is much longer than systems available in the US employ.
