Purilens Plus Saline has been on the market in 4oz bottles for more than 20 years. It became the go-to "buffered" preservative-free saline after Alcon discontinued Unisol 4 in 2015, and in fact, it was the only solution of its type on the US market until Bausch & Lomb introduced Scleralfil in 2017. (A few years later, Contamac introduced , another type of buffered saline.)

What people use Purilens for

• Rinsing sclerals: For those who are new to sclerals and need extra saline while refining their insertion and removal skills, or for anyone who needs a lot of saline for rinsing off cleaning solutions or while removing/rinsing and re-inserting lenses during the day - using a bottle is more convenient than individual vials. For your safety, don't stretch it beyond the 14 days.
• Rinsing soft contacts: Purilens is popular for rinsing off the solution that daily contact lenses come packaged in. If this is you, we urge you to get the 2oz bottles and throw them away after 14 days. This is a preservative-free multi-use bottle which can easily get contaminated, and rinsing lenses with contaminated solution increases your risk of infection.
• Filling sclerals: Purilens is the cheapest buffered preservative-free saline. Please consult your provider about whether it is suitable for filling your lenses. While this is part of the formal product labeling, scleral lens users tend to be higher risk and your provider may not want you using this saline for the full 14 days (let alone stretching it beyond).

Careful!

Never soak your lenses in Purilens! Storing contact lenses in preservative-free solutions is a risk factor for Acanthamoeba keratitis.

Indications

Purilens Plus Preservative-Free Saline is indicated for use following proper lens disinfection as recommended by the eyecare practitioner. Purilens Plus Preservative-Free Saline is for rinsing soft (hydrophilic), rigid gas permeable and hard contact lenses prior to lens insertion. This solution may also be used as an insertion solution for large diameter (scleral) contact lenses, as a rinse for contact lens cases, and may be used as needed throughout the day to rinse contact lenses.

Directions

See Instructions for Use for important safety information. 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. Re-close the bottle after use. Always wash and rinse your hands before you handle your lenses. Rinse and clean your contact lenses each time you remove them. Rinse your lens thoroughly with Purilens Plus Preservative-Free Saline by holding the lens between the forefinger and thumb of one hand and directing a steady stream of the saline onto the lens for ten (10) seconds. Always rinse the same lens first, right or left, to avoid mix-ups, and put that lens into the correct chamber of a storage case. Repeat the procedure for the second lens.

• Always thoroughly wash hands when handling contact lenses.
• Never re-use solution.
• Do not use if unused, unpierced bottle is damaged and leaking.
