Between Two Similar GP Care Systems
MICHAEL A. WARD, MMSC, FAAO
The GP lens care product Claris (Menicon)
will no longer be on the market once current supplies are exhausted. However, two
alternatives are available: Optimum by Lobob and MeniCare (Menicon).
This non-abrasive GP lens cleaner/disinfectant-type system has a history of working
very well with GP lenses including plasma-treated GPs and the softer, high-Dk
Claris, Optimum and now MeniCare products originated from the
former Sherman Pharmaceuticals' De-Stat RGP lens care products. Two generations,
De-Stat 3 and De-Stat 4, later became Optimum and Claris, respectively. Advanced
Medical Optics most recently manufactured Claris, which was distributed in the United
States by Menicon authorized laboratories.
Now that Claris is off the market, we have Optimum and MeniCare.
Lobob makes both. What are the differences and similarities of these current products?
More Similar than Different
Claris and MeniCare are both two-part systems that contain a combined
cleaning, disinfecting and storage solution (CDS) and a separate wetting/rewetting
drop (WRW). The Optimum system incorporates an additional extra strength cleaner
(ESC). Optimum by Lobob Cleaning, Disinfecting and Storage Solution (CDS) and MeniCare
GP by Menicon Cleaning, Disinfecting and Storage Solution (CDS) have the same ingredients:
Lauryl sulfate salt of imidazoline and octylphenoxypolyethoxyethanol, with benzyl
alcohol 0.3% and disodium edetate 0.5% as preservatives. The CDS products are used
for rub-and-rinse as well as for overnight storage and disinfection. Patients should
not use this solution in their eyes, and the bottle has a red dispenser tip to warn
Following overnight storage in the CDS, patients must rinse
the lenses with either water or saline before application. My preference is sterile
aerosol saline for the morning rinse. Patients should apply a wetting agent to the
lens before application.
The Optimum by Lobob Wetting/Rewetting (WRW) Drop and in-the-eye
Lubricant and the MeniCare by Menicon Wetting/Rewetting (WRW) Drop and in-the-eye
Lubricant also both have the same ingredients, although they don't appear in the
same order in the package insert. They both contain: Polyvinyl alcohol, polyvinylpyrrolidone,
hydroxyethyl cellulose, sodium and potassium chloride, sodium carbonate and sodium
bisulfite 0.02%, with benzyl alcohol 0.1%, disodium edetate 0.1% and sorbic acid
0.05% as preservatives. This product wets the lenses prior to application and/or
serves as a lubricating drop.
The Optimum Extra Strength Cleaner (ESC) is preservative-free
and contains cocoamphodiacetate and glycols in an aqueous solution. It may be used
daily or occasionally. It contains no abrasives.
The Bottom Line
In short, Optimum CDS and WRW are the same as MeniCare CDS and
WRW. Optimum products are available through eyecare practitioners as well as retail
and Internet outlets, while MeniCare products are available only through practitioners
and Menicon Authorized Labs.
