Rebecca's description

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.

What people use Purilens for

• Rinsing sclerals: Purilens is great 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. However, the bottles tend to get used for too long. This is a preservative-free multi-use bottle which can easily get contaminated, and rinsing lenses with contaminated solution increases your risk of infection. So, if you are a soft lens user, I recommend the 2oz bottles (discard after 14 days) or switch to single-use vials. 
• Filling sclerals: Purilens is the cheapest buffered (pH balanced) preservative-free saline. Please consult your provider about whether it is suitable for filling your lenses, as some providers have concerned about using this up to the full 14 days that it is labeled for. While this is part of the formal product labeling, scleral lens users tend to be higher risk, so your doctor's input is important.

Careful!

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

Alternatives?

• ScleralFil, a borate-buffered saline which is sold in 10mL single-use vials (box of 30). ScleralFil has the same ingredients as Purilens.
• Unbuffered salines such as LacriPure and the off-label nebulizer salines such as Addipak and Modudose, are options for many users.

Warnings

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. 

Precautions

• Do not use if unused, unpierced bottle is damaged and leaking.
• Never reuse solution
• Do not transfer saline solution to another container
• [IF USING IN A SPECIAL CLEANING UNIT] Fresh solution should be used for every cleaning/disinfection cycle
• Do not store lenses in water, or in a non-sterile solution
• Use before expiration date stamped on container
• After breaking the original seal, keep container tightly closed when not in use
• Discard bottle and contents 14 days after opening. Record dated opened in space provided on bottle label
• Never touch the tip of container to any surface

Adverse reactions

The following problems may occur

• Eye stinging, burning, or itching (irritation)
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (visual acuity)
• Blurred vision
• Sensitivity to light (photophobia) 
• Dry eyes

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. 

Directions for use

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

• 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. 
• Repeat the procedure for the second lens.
