As many as 59% of patients with medically treated glaucoma report symptoms of ocular surface disease, often attributed to preservatives in eye drops [1.7.1]. When asking, 'Does brimonidine contain BAK?', the answer depends entirely on the specific product, as both BAK-preserved and BAK-free options exist [1.2.3].

According to the manufacturer, the standard multi-dose bottle of Refresh Tears uses the gentle, oxidizing preservative known as **Purite® (stabilized oxychloro complex)**, which is designed to break down into natural tear components upon contact with the eye. This advanced technology aims to provide the antimicrobial benefits of a preservative while minimizing potential irritation for users with mild to moderate dry eye symptoms.

Over 70% of ophthalmic solutions contain a preservative, and one modern alternative to harsher options is stabilized oxychloro complex. Known by the brand name Purite, this gentle, oxidizing preservative is used in many popular eye drops to maintain sterility without causing significant harm to the delicate ocular surface.

In ophthalmology, a 2003 study on rabbits showed eye drops containing Purite were significantly better tolerated and caused less corneal damage than those with the older preservative benzalkonium chloride (BAK). Known pharmacologically as stabilized oxychloro complex (SOC), **what is Purite** and why is it considered an advanced solution for maintaining sterility in multi-dose eye care products while minimizing irritation?.
