Lacripure is an unbuffered preservative-free saline (0.9% sodium chloride solution) packaged in 5mL vials. It comes in a box of 98 vials. For people who need very little saline per session, it can last up to 3 months.

As an unbuffered saline, Lacripure is slightly acidic, though its pH seems to be significantly higher than the inhalation solution which are sometimes recommended for use with scleral lenses for cost savings.
