Cataract surgery, glaucoma procedures, corneal transplantation, and intraocular lens implantation all require precise surgical environments where tissue protection and space maintenance are critical. This is why the choice of an ophthalmic viscosurgical device (OVD) has become one of the most important factors influencing surgical outcomes.
Among various viscoelastics in ophthalmology, sodium hyaluronate-based ophthalmic viscoelastic devices have emerged as the gold standard for many ophthalmic surgeons worldwide. Their superior biocompatibility, excellent chamber maintenance, and endothelial cell protection have made them the preferred choice over alternative materials such as hydroxypropyl methylcellulose (HPMC).
In this article, we explore why sodium hyaluronate continues to dominate the OVD market and how Singclean® OVD delivers reliable performance for distributors, hospitals, and ophthalmic clinics.
What Is an Ophthalmic Viscoelastic Device?
An ophthalmic viscoelastic device is a sterile polymer solution used during eye surgery to:
Maintain anterior chamber depth
Protect corneal endothelial cells
Separate ocular tissues safely
Facilitate intraocular lens implantation
Reduce mechanical trauma caused by surgical instruments
Without a properly selected ophthalmic viscosurgical device, surgeons may face challenges such as chamber collapse, endothelial cell damage, poor visibility, and increased surgical complexity.
According to the Singclean OVD product portfolio, sodium hyaluronate-based OVDs help maintain chamber stability during phacoemulsification while minimizing tissue trauma and enhancing surgical visibility.
Excellent Space Maintenance During Cataract Surgery
Cataract surgery remains the largest application segment for ophthalmic viscoelastic devices globally.
During phacoemulsification, maintaining anterior chamber depth is essential because surgeons need adequate working space while protecting delicate ocular structures.
The effectiveness of sodium hyaluronate largely depends on molecular weight and viscosity.
Clinical Comparison: Sodium Hyaluronate vs HPMC
| Parameter | Typical HPMC OVD | Singclean Sodium Hyaluronate OVD |
|---|---|---|
| Molecular Weight | ~86,000 Da | 1,000,000–2,600,000 Da |
| Viscosity | 3,000–5,000 mPa·s | ≥100,000 mPa·s |
| Classification | Dispersive | Cohesive |
| Chamber Maintenance | Moderate | Excellent |
| Removal Efficiency | Moderate | Excellent |
The significantly higher molecular weight and viscosity of sodium hyaluronate provide better chamber stability throughout repeated instrument insertion and manipulation.
For complex cataract surgeries, this stability translates into:
Better surgical control
Reduced endothelial trauma
Improved visibility
Enhanced surgeon confidence
Cohesive Properties Simplify Surgical Workflow
OVDs are generally classified into:
Cohesive OVDs
Dispersive OVDs
Viscoadaptive OVDs
Each category has its own advantages, but cohesive OVDs remain popular because they maintain space effectively and can be removed as a single mass after surgery.
Singclean® OVD is classified as a cohesive ophthalmic viscosurgical device. It forms a unified viscoelastic mass that:
Maintains intraocular space
Stabilizes ocular tissues
Simplifies aspiration
Helps minimize postoperative pressure spikes
These characteristics are particularly appreciated by surgeons performing routine cataract procedures.
