Xailin Intense is indicated in cases of low tear production (dry eye syndrome), accompanied by symptoms such as dry eyes, burning or eye fatigue.

These symptoms can be caused by working in front of a computer monitor, watching television for extended periods, or exposure to dry air from heating or air conditioning, or to tobacco smoke. Reduced tear production can also occur after surgery or an eye injury, as constant hydration is necessary for the proper regeneration of the eye's surface structures. Xailin Intense contains a high concentration of sodium hyaluronate, which keeps the cornea and conjunctiva hydrated for a long time.

Sodium hyaluronate is a viscoelastic liquid with hygroscopic properties that plays numerous important roles in the human body. It is a natural lubricant, consisting of a biocompatible polysaccharide with excellent water-retention properties. Hyaluronic acid in the eye is found in the vitreous humor, lacrimal gland, conjunctiva, cornea, and tear fluid.

For many years, sodium hyaluronate solutions have been widely and successfully used in ophthalmic applications worldwide. Sodium hyaluronate has the ability to form a stable moisturizing film on the surface of the eye. Therefore, a single application provides increased comfort for hours for those suffering from dry eye syndrome, as well as for contact lens wearers.
