Chondroitin Sulphate Provides Enhanced Endothelial Coating1-4

TW-DCV-2300001

Chondroitin sulphate is designed with a double negative charge and when combined with sodium hyaluronate, creates a triple negative charged product. This results in improved adhesion to positively charged endothelial tissue.1-4*

Dark blue circle with the number “-1” in the middle to indicate the charge for sodium hyaluronate. 2 blue interlocking circles both with the numbers “-1” in the middle to indicate chondroitin sulphate’s double negative charge. There is a plus sign between the dark blue circle and the 2 blue interlocking circles to illustrate that when sodium hyaluronate is combined with chondroitin sulphate, a triple negative charge occurs.

*Compared to only-Na-Hyaluronate OVDs

Viscoelastic products containing chondroitin sulphate improve OVD retention.2* 

 

Chondroitin sulphate-containing viscoelastic products demonstrate superior retention and coating of the endothelium under stress from high flow conditions. This leads to less endothelial cell loss and less corneal edema.1-3,5-7

A visual comparison between OVDs that do not contain chondroitin sulphate and OVDs that do contain chondroitin sulphate. The OVDs that do not contain chondroitin sulphate are PROVISC, Healon, Healon 5 and Amvisc. The OVDs that do contain chondroitin sulphate are VISCOAT and DisCoVisc. OVDs with chondroitin sulphate retained 325 µm under high flow while others retained 0 µm.

3 blue interlocking circles. Inside the first circle white text reads “Pre Phaco.” Inside the middle circle white text reads “Phaco.” Inside the last circle white text reads “IOL Delivery.”

DuoVisc®, as a combination of cohesive and dispersive products, meets each of your procedural needs and preferences to allow a variety of surgical techniques. Following the proven methodology helps to maximise the advantages and minimises the disadvantages of both products.8

 

Range of Volumes to Cover Each Step of the Procedure

 

The required amount of OVD depends on a variety of factors, including the procedure, technique and surgeons' preference. With this in mind, Alcon OVDs are available in several volumes to fit your needs – even more than 1mL.
