    About Unique pH Multi-Purpose Solution

    • Multi-purpose solution for RGP lenses
    • Compatible with Hydra-PEG lens coating
    • Available in 4oz (120mL) or 2.5oz (75mL) size
    • Includes a free lens case

    Description (by Rebecca)

    We originally added Unique pH to The Dry Eye Shop's scleral lens care products specifically because of its compatibility with the new Hydra-PEG coating. For optimal performance of scleral lenses it's generally accepted that digital (i.e. rub) cleaning on a daily basis is necessary, not just overnight disinfection. However, Lobob ESC, the gold standard "rub" cleaner for scleral lenses, is not compatible with Hydra-PEG (a relatively new lens coating that improves lens wettability).

    Unique pH is a multi-purpose solution that is approved by the Hydra-PEG makers for their coating, and it can be used for both rub cleaning and overnight soaking. At this point it's quite popular for daily disinfection of sclerals.

    I will always stick with hydrogen peroxide (Clear Care) as the best way to disinfect overnight. But I find Unique pH very handy for travel - traveling with peroxide is just not practical. So I tend to use it often when I'm on the road. It's a very good product.

    SAFETY NOTE: As with ALL multi-purpose solutions, DO NOT put this solution in the 'bowl' of your scleral lens. It is strictly for cleaning and disinfection, not filling.

    Description (from the manufacturer's literature)

    • A multi-purpose solution for gas permeable contact lenses
    • Cleans, conditions, and disinfects in one bottle
    • Provides customized lens wear, comfort-based on individual tear pH
    • Novel formula adjusts solution characteristics for lens care
    • Product is available in a 4oz (120ml) or 2.5oz (75ml) bottle and includes a FREE lens case
    Unique pH ® is a highly effective and well-respected multipurpose solution for gas permeable contact lenses.
    Soaking your gas permeable contact lenses in Unique pH ® removes dirt, protein deposits and debris. No separate daily cleaner is required.
    This solution conditions lenses by adjusting to the eye's natural tear pH to enhance the wettability and comfort of gas permeable contact lenses on insertion. This formula is designed to provide a soothing effect during lens wear.
    The solution disinfects lenses using antimicrobial agents, which destroy harmful microorganisms (germs), commonly found on the surfaces of lenses.
    Unique pH ® Multi Purpose Solution may also be used to dilute a daily protein remover for simultaneous enzymatic cleaning during conditioning.
    Travel-friendly bottle size for carry-on convenience. Unique pH ® is available in a convenient travel size designed to meet TSA guidelines for carrying liquids on board an aircraft. The Unique pH ® Travel Pack contains a two fluid ounce (60 mL) bottle of Unique pH ® and a lens case.
    How supplied
    Unique pH ® is supplied in a sterile 4 fl. oz. (120 mL) or 2.5 fl.oz. (75 mL) size. Each unit carton includes a free lens case. Unique-pH multi-purpose solution is a proprietary sterile, aqueous solution buffered to approximate the pH and tonicity of the eye. It contains hydroxypropyl guar, a proprietary wetting/conditioning polymer system, polyethylene glycol, tetronic (tetronic is a registered trademark of basf) 1304, boric acid, propylene glycol, and is preserved with polyquad (polyquaternium-1) (0.0011%), and edetate disodium (0.01%)

    My Favorite Hydra-PEG-Compatible Cleaner

    tl;dr version: Better than Boston Simplus and Tangible Clean

    I've been on a rollercoaster journey trying to find the best solution for my scleral lenses since I got them in July. My doctor recommended Clear Care for daily cleaning and Boston One Step Enzymatic Cleaner once a week for protein buildup. I quickly learned that the One Step product was NOT OK to use with my Hydra-PEG coating. I like Clear Care, but I also wanted something I could use when I'm not at home that didn't have a 6-hour wait time before reusing the contacts. I tried Boston Simplus and DID NOT like it at all. It was too viscous, I didn't like having to do the cleaning in the morning, and it always made me feel like there was something in my eye after using it. I then tried Tangible Clean and this product, Menicon Unique pH. While I like that Tangible Clean is made by the same company as Hydra-PEG. It's just a little too watery. Unique pH, in my opinion, iss a great middle-of-the-road product.

    Menicon Unique pH Multi-Purpose Solution

    This product is not available locally so I was very glad when The Dry Eye Shop began stocking it in late 2017.

    When I got my scleral lenses in April 2017 my optometrist provided me with a 4 oz. bottle of Unique pH. He did not stock Unique pH. I used the original bottle for several months in conjunction with Clear Care Plus for weekly cleaning. The 4 oz. size was not convenient for airline travel, however.

    Prior to The Dry Eye Shop carrying this product, and with no source for Unique pH that I could find, I used Boston Simplus (see my review of this solution).

    I have been using the 2 oz. travel size bottle of Unique pH for a while, after finishing the bottle of Boston Simplus. It is a fat little plastic bottle 1 3/4 inches in diameter and 3 3/4 inches tall, so it is not a small package.

    My preference for this product derives from the following: it is safe to use in the eye, is the consistency of saline solution (perhaps a bit “watery”, especially compared to very viscous Boston Simplus), and is used BEFORE storing the lenses overnight (as opposed to Boston Simplus, which is used AFTER storage – again, see my review of this product). NOTE FROM REBECCA: Thanks Jeff - as always - love all the detail you provide! - Rebecca
