What is Viscoat?
Viscoat®, a combination of sodium hyaluronate 3% and chondroitin sulfate 4%, has the typical properties of a dispersive OVD, while Visthesia® Intracameral, a formulation of sodium hyaluronate 1.5% and lidocaine hydrochloride 1%, demonstrates as a cohesive one [7-9].
What is Viscoat in cataract surgery?

What is viscoelastic used in eye surgery?
Viscoelastics, also referred to as ophthalmic viscosurgical devices, or OVDs, are viscous substances that allow us to make phacoemulsification easier and safer. Once the first incision is made into the eye, it has a tendency to collapse as the aqueous leaks out.
What is the use of Viscoat?
Uses of Viscoat: It is used for eye surgeries.
What are viscoelastic agents?
Medications for Ophthalmic Viscoelastic Agent. Ophthalmic Viscoelastic Agent is a gel injected into the anterior chamber during ophthalmic surgery to maintain the depth of the chamber, protect the corneal endothelium, and stabilize the vitreous.
What viscoelastic means?
Definition of viscoelastic : having appreciable and conjoint viscous and elastic properties such viscoelastic materials as asphalt also : constituting or relating to the state of viscoelastic materials viscoelastic data viscoelastic properties.
What are the different types of viscoelastics?
While there are many viscoelastics available on the market, there are two main classes: dispersive and cohesive. What are the differences and when do you use each? Which is better for each step of the surgery?
What is the best viscoelastic material for intraocular surgery?
Among viscoelastic substances, sodium hyaluronate has become the most popular for intraocular surgeries since the introduction of Healon®(sodium hyaluronate 1%, 4 × 106daltons) in 1979.
Why do we use viscoelastics in cataract surgery?
Use of a viscoelastic can make phacoemulsification easier for the surgeon as well as safer for the patient. It is for this reason that is has become an integral part of our surgeries. Click below for a video of this cataract surgery with a focus on the viscoelastics:
Why are cohesive Viscoelastics used in plastic surgery?
The cohesive viscoelastics tend to stick together as a single mass and are therefore usually easier to fully remove. Use of a viscoelastic can make phacoemulsification easier for the surgeon as well as safer for the patient. It is for this reason that is has become an integral part of our surgeries.
