INTENDED PURPOSE OF VISCOELASTIC
Ophthalmic viscosurgical devices are intended to be used during posterior and anterior segment surgery in the human eye to create and maintain space, to manipulate intraocular tissue and to protect the corneal entothelium.
INDICATION FOR USE
Viscoelastics are for use during anterior segment intraocular surgery, such as cataract extraction and IOL implantation. It has to be entirely removed from the eye after completion of the procedure.
Viscoelastic is not FDA approved and is currently unavailable in the US
EyeCoat
HPMC
EyeCoat is a 2% hydroxypropyl methylcellulose (HPMC) viscoelastic with a nominal viscosity of 3,000 cPs. It is non-organic; water soluble; enzyme resistant, which helps provide viscosity stability during storage; and pH stable. 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 endothelilum, while it effectively maintains space and gently manipulates delicate intraocular tissue.
EyeCoat Plus
HPMC PLUS
EyeCoat Plus is a higher viscosity 2% hydroxypropyl methylcellulose (HPMC) viscoelastic with a nominal viscosity of 40,000 cPs. It is non-organic; water soluble; enzyme resistant, which helps provide viscosity stability during storage; and pH stable. Viscoelastic Plus 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 endothelilum, while it effectively maintains space and gently manipulates delicate intraocular tissue.
EyeCoat SH
EyeCoat SH comes in a range of 1% to 3% sodium hyaluronate viscoelastic with a possible viscosity range of 2,000cPs > 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. HA viscoelastics are especially suited for phaco emulsification. HA viscoelastics may also be used to coat intraocular lenses and ophthalmic surgical instruments during cataract extraction and intraocular lens implantation.
