Sodium Hyaluronate
Sodium hyaluronate viscoelastic is available in a range from 1% to 3% with a possible viscosity range of 2,000cPs to ≥ 75,000cPs. Viscoelastic SH is clear, sterile and non-pyrogenic. Sodium hyaluronate viscoelastics have been demonstrated to have a high degree of biocompatibility. Its cohesive characteristics are especially suited for phacoemulsification since its higher viscosity enables it to effectively maintain space and gently manipulate delicate intraocular tissue. It is also used during glaucoma filtering, corneal transplantation and retinal attachment. SH viscoelastics may also be used to coat intraocular lenses and ophthalmic surgical instruments during cataract extraction and intraocular lens implantation.
HPMC / HPMC PLUS
HPMC viscoelastic is non-organic, water soluble and enzyme resistant which helps to provide viscosity and pH stability during storage. Viscoelastic is clear, sterile and non-pyrogenic. HPMC viscoelastics have been demonstrated to have a high degree of biocompatibility. Its dispersive characteristics are especially suited for protecting the endothelium, while it effectively maintains space and gently manipulates delicate intraocular tissue.
HPMC 2% has a nominal viscosity of 3,000 cPs.
HPMC Plus 2% a nominal viscosity of 19,000 cPs.
