What Are Hypertonic Saline Drops?
Hypertonic saline drops are eye drops that contain a higher salt concentration than normal tears. They are used to temporarily relieve corneal edema, which is swelling of the clear front surface of the eye. Sodium chloride 2% and 5% are common ophthalmic hypertonic saline strengths. These drops do not cure the cause of swelling but can help draw excess fluid out of the cornea.
