Avenile® is a sterile, isotonic, non-pyrogenic viscoelastic solution of highly purified, noninflammatory, 2% HPMC with a high molecular weight greater than 80000 daltons. Each mL provides 20 mg of HPMC dissolved in a physiological balanced salt solution. The osmolarity of Avenile® is 285±32 mOsm, the viscosity of 4000±1500 cP, and the pH of 7.2±0.4. Avenile® is considered for use as an ophthalmic surgical aid in anterior segment surgical procedures, including cataract extraction and the implantation of an intraocular lens. Avenile® maintains a deep chamber during anterior segment surgery, thereby allowing for more efficient manipulation with less trauma to the corneal endothelium and other ocular tissues. Each package of Avenile® contains one prefilled syringe of 2ml, one sterile disposable needle, a leaflet and a set of tracking labels.
