Experience the Difference with ClearVisc™ Viscoelastic

Dr. K. Alex Dastgheib is in private practice in Garden Grove and Newport Beach, California with more than 20 years’ experience in cataract surgery. The Dastgheib Pioneer Award in Ocular Innovation, established in 2014, is given annually at Duke University for his pioneering work in 1992-1994 in establishing the presence of VEGF in neovascular AMD. Recipients of this award have made a major change in the practice of ophthalmology.

Dr. Dastgheib spoke with us about his experience using the ClearVisc (2.5% sodium hyaluronate) dispersive viscoelastic. He noted several key advantages to ClearVisc.

ClearVisc Contains Sorbitol for Free Radical Protection

Phacoemulsification causes water molecules to disintegrate, which releases free radicals. The free radicals can lead to corneal endothelial damage by attacking healthy cells and causing oxidative stress and cell damage.1

ClearVisc provides dual-action physical and chemical protection during cataract procedures. ClearVisc was designed to optimize physical endothelial cell protection due to the molecular weight and viscosity of the viscoelastic.2 The chemical protection is due to the proprietary formulation that contains both sodium hyaluronate and sorbitol.1,3 ClearVisc with sorbitol chemically bonds to free radicals to provide a high level of free radical scavenging activity.1,3 ClearVisc is the only dispersive ophthalmic viscosurgical device (OVD) in the United States that contains sorbitol. Moreover, laboratory data has demonstrated that ClearVisc delivers superior free radical protection compared to other dispersive OVDs.1,3

Real-World Advantage of ClearVisc Is Clear

“In real life, when using ClearVisc, corneas look very clear the day after cataract surgery”.3 Clinical data for ClearVisc supports this – in a clinical study, on postop day 1, 91% of corneas were clear and this increased to 100% at postop week 1.3 This property of ClearVisc is important in extreme, blinding cataracts as they require additional ultrasound energy.

Easy to Remove

In Dr. Dastgheib’s experience, ClearVisc is removed quickly and easily at the end of the procedure. Despite a best effort to remove all of the viscoelastic out at the end of every case, occasionally there is an intraocular pressure (IOP) spike the day after surgery, which may be attributed to viscoelastic that remained in the eye.2 With ClearVisc, Dr. Dastgheib is confident he can remove the viscoelastic quickly and completely.

1 mL Syringe Volume

ClearVisc is supplied in a 1 mL syringe, which is almost double the volume of other OVDs. For patients with bigger anterior chambers, there is enough ClearVisc in one syringe for the entire case, according to Dr. Dastgheib. This is also an advantage for dense cataracts where additional viscoelastic is often required - the 1 mL of ClearVisc provides enough OVD for the procedure. In the clinical trial of ClearVisc, 95.1% of surgeons did not need a second syringe of OVD.3 Using only one syringe may have cost advantages.

An additional feature of ClearVisc that Dr. Dastgheib appreciates is the inclusion of a retention clip in the package. The retention clip decreases the risk of the cannula moving when the surgeon presses the plunger in the eye. While a rare occurrence, a cannula can disconnect and fly into the eye if it is not securely fastened.
