PURPOSE & HANDLING

Chamber stability and
confident surgical flow.

PURE‑VISC maintains anterior chamber depth, protects intraocular structures, and supports confident surgical manipulation, with a higher-viscosity feel built for space and support.

Chamber Maintenance

Maintains stable anterior chamber depth throughout surgical manoeuvres for confident, controlled procedures.

Consistent ~9000 cps Hold

Formulated at a higher working viscosity so it creates and holds anterior chamber space where firmer mechanical support is needed.

Endothelial Protection

HPMC coats and protects the corneal endothelium during phacoemulsification and IOL implantation.

PFS Convenience

Prefilled syringe format eliminates preparation — ready for immediate, consistent delivery.

HOW VISCOELASTICS WORK

How HPMC viscoelastics
support cataract surgery.

HPMC-based OVDs are established anterior-segment surgical adjuncts that coat surfaces, maintain space, and protect tissue. PURE‑VISC’s higher viscosity is formulated to favour space maintenance and chamber support.

STEP 01

Chamber Injection

HPMC viscoelastic is injected into the anterior chamber, immediately creating a stable working space.

STEP 02

Surface Coating

Its higher-viscosity HPMC formulation is designed to hold its position and maintain a protective, stable layer through phacoemulsification.

STEP 03

Space Maintenance

Maintains anterior chamber depth throughout the procedure, preventing collapse and supporting confident manipulation.

STEP 04

Easy Removal

At close of surgery, the viscoelastic is aspirated. HPMC is designed for straightforward removal from the anterior chamber.

FREQUENTLY ASKED QUESTIONS

Common questions about
HPMC viscoelastics.

What is HPMC ophthalmic viscoelastic used for?
HPMC viscoelastic is used during cataract surgery to maintain anterior chamber depth, protect corneal endothelium, facilitate IOL implantation, and create working space. HPMC OVDs are generally described in the literature as having dispersive-leaning coating behaviour, though the precise classification depends on each product’s own rheological testing.
Should I use PURE‑VISC or OP‑VISC?
It depends on what you need the OVD to do at that step of surgery. If you need it to create or hold space, PURE‑VISC’s higher viscosity is the more logical choice. If you need it to coat, spread or flow, OP‑VISC’s lower viscosity fits better. See the full step-by-step comparison for guidance through each stage of surgery.
Is PURE‑VISC available in a prefilled syringe?
Yes. PURE‑VISC is supplied in a 3 ml prefilled syringe, ready for immediate use in theatre with no decanting or loading step.
Who manufactures these viscoelastics?
PURE‑VISC is manufactured by Agaaz Ophthalmics, an Indian manufacturer and global exporter of ophthalmic surgical products.
