Purilens Plus Saline

Purilens Plus is a pH balanced preservative-free saline sold in 4oz or 2oz bottles. It is buffered, i.e. it has additives to maintain a pH similar to the eye, and has the same ingredients as ScleralFil.

Purilens is popular scleral lens users who need a lot of saline each day, either because they are new, or because they need extra saline for multiple lens insertion attempts, or because they remove, clean and re-apply their lenses during the day.

Unlike most salines sold for scleral lenses, Purilens is packaged in a multi-dose bottle rather than a single-use vial. Due to the lack of preservative, these bottles can become contaminated. Be very careful to avoid touching the tip of the bottle to your lenses, eyes, or any surface.

According to the manufacturer’s labeling, the bottles must be discarded within 14 days. You can use Purilens for rinsing lenses for the full 14 days. However, we recommend consulting your provider about whether they feel it is acceptable to use Purilens for filling your scleral lenses for the entire 14 days. Many providers have a shorter recommendation due to the potential for contamination after opening the bottle. For example, the PROSE Use and Care Guide from BostonSight instructs patients to use Purilens for filling no longer than 48 hours after opening the bottle.

Some providers recommend refrigerating this product.

The Purilens caps are the “puncture” type: you remove the cap, remove a white plastic ring, then replace the cap and screw it in fully to puncture the sealed bottle top.
