Sodium hyaluronate

(brand names: Euflexxa, Hyalgan, Supartz, Gel-One) is used to treat knee pain in patients with osteoarthritis who have not received relief from other treatments. It is very similar to the lubricating fluid that occurs naturally in the articular capsule of the knee joint. Once injected into the joint capsule, it acts as both a shock absorber and a lubricant for the joint.

(brand names: Healon, Provisc, Viscoat) is used as a surgical aid in variety of surgical procedures performed on the eyeball including cataract extraction (intra- and extracapsular), intraocular lens implantation, corneal transplant, glaucoma filtration, and retina attachment surgery. In surgical procedures in the anterior segment of eyeball, instillation of sodium hyaluronate serves to maintain a deep anterior chamber during surgery, allowing for efficient manipulation with less trauma to the corneal endothelium and other surrounding tissues. Its viscoelasticity also helps to push back the vitreous face and prevent formation of a postoperative flat chamber. In posterior segment surgery, sodium hyaluronate serves as a surgical aid to gently separate, maneuver, and hold tissues. It creates a clear field of vision, facilitating intra-operative and post-operative inspection of the retina and photocoagulation.
