Viscoelastic Solutions, Intraocular

Definition : Solutions that have viscous and some elastic properties formulated in appropriate concentrations for use during and after intraocular procedures. These solutions typically consist of aqueous mixtures containing as main components compounds such as sodium hyaluronate, a purified sodium salt of hyaluronic acid (a glycosaminoglycan [GAG]); chondroitin sulfate, a sulfated GAG; polymers with a long molecular chain ( hydroxypropylmethylcellulose [HPMC]); or a combination of these. Intraocular viscoelastic solutions are usually supplied in sterilized pre-filled syringes or vials; syringes containing two solutions with different physicochemical properties each intended for a specific intraocular purpose are also available. The solutions may be intended for use, but are not limited to, the temporary replacement for the vitreous humor of the eye.
