What is Healon EndoCoat?

HEALON EndoCoat® OVD is an ophthalmic viscoelastic containing 3% sodium hyaluronate indicated for use as a surgical aid in patients undergoing ophthalmic anterior segment procedures including: Cataract surgery with an intraocular lens.

Who makes Healon?

HEALON® PRO Ophthalmic Viscoelastic Device | Johnson & Johnson Vision.

What is Viscoat used for?

The main reason for using OVDs in cataract surgery is to prevent damage of the corneal endothelium. Dispersive OVDs, such as Viscoat, are considered to protect the endothelium better than cohesive OVDs, because of their lower specific surface properties [2].

What is DuoVisc?

DuoVisc is a packet containing 2 ophthalmic viscosurgical devices (OVDs): the dispersive Viscoat, which was used for intraocular lens (IOL) implantation. In the Viscoat group, the Viscoat was used during the entire surgery.

What is Healon made from?

The Healon OVD contains 10 mg/mL of sodium hyaluronate dissolved in physiological sodium chloride phosphate buffer (pH 7.0-7.5). This high molecular weight polymer is made up of repeating disaccharide units of N-acetyl-glucosamine and sodium glucuronate linked by ß 1-3 and ß 1-4 glycosidic bonds.

What is the use of viscoelastic in eye surgery?

The major aim for the application of viscoelastic substances in cataract surgery is prevention of corneal endothelial cell loss. This aim is fulfilled by deepening of the anterior chamber, mechanical endothelium protection against surgical trauma, absorption of ultrasound energy, and coating of intraocular lens.

Is Healon dispersive or cohesive?

A new class of OVDs was created when AMO introduced Healon 5, which is a pseudo-dispersive, ultra-viscous cohesive. This is a visco-adaptive OVD which behaves as a super- cohesive viscoelastic to pressurize and create space, yet can provide the protection of dispersives.

What is the purpose of viscoelastic?

Is DuoVisc a medication?

In the US, DuoVisc is a member of the drug class ophthalmic surgical agents and is used to treat Ophthalmic Viscoelastic Agent.
