Purilens Plus Saline has been on the market for about 20 years. However, it was not nationally known until 2016. When Unisol 4 was discontinued - followed soon after by Simply Saline, another borate-buffered preservative-free saline - Purilens Plus quickly became the go-to product for people seeking buffered preservative-free saline, including for use filling scleral lenses. In fact, it was the only equivalent on the US market until Bausch & Lomb introduced Scleralfil in 2017. (A few years later, Contamac introduced Nutrifill, another type of buffered saline, which is a particular favorite.) Then Purilens brought out 2oz bottles as a smaller alternative.
Filling scleral lenses was an "off-label" use of Purilens for. along time, ust as it had been for Unisol 4. Recently, Purilens Plus has been FDA cleared for filling sclerals. At the same time, however, there have been studies that show a concerning level of risk of contamination in open Purilens bottles. Many physicians recommend not using Purilens for filing scleral lenses, at least not more than 48 hours after opening a bottle. Please consult your scleral lens specialist for instructions! Safety matter!
Purilens remains a popular product for many scleral lens users because it is the most cost-effective buffered preservative-free saline. For those who have frequent rinsing needs, it's a particularly helpful product.

PuriLens solution is sterile prior to opening. Because it contains no preservatives, it will not remain sterile indefinitely after opening and, therefore, should not be used as an eye drop. Do not touch the tip of the container to any surface since this may contaminate the solution. DO NOT USE IF SOLUTION IS CLOUDY OR DISCOLORED.
If you notice any of the above problems, remove and examine your lenses. If the problem stops and the lenses appear to be undamaged, rinse your lenses using PuriLens solution, then clean and disinfect the lenses in your PuriLens unit and reinsert them. If the problem continues or a lens appears to be damaged, IMMEDIATELY remove your lenses and IMMEDIATELY consult your eye care practitioner. Do not reinsert a damaged lens.
If any of the above symptoms occur, a serious condition such as infection, corneal ulcer, neovascularization or iritis may be present. Seek immediate professional identification of the problem and treatment to avoid serious eye damage.
Inside the bottle cap is a molded insert that will pierce the container. To open the bottle, first remove the cap and discard the white plastic restraining ring. Avoid touching the tip of the bottle. Replace the cap then press down and turn the cap clockwise to pierce the container.
Rinse, clean, and disinfect your lenses each time you remove them.
Rinse your lens thoroughly with PuriLens solution by holding the lens between the forefinger and thumb of one hand and directing a steady stream of PuriLens solution onto the lens for ten (10) seconds.
Always rinse the same lens, right to left, first to avoid mix-ups and put that lens into the correct chamber of the lens storage case.
