Viscoelastics for Eye Surgery: What They Are and Why They Matter

Viscoelastics, or ophthalmic viscosurgical devices (OVD), are viscous materials used during ophthalmic surgery — especially cataract surgery — and play a key role in preserving the surgeon’s working space.

Main Functions of Viscoelastics

• Maintain the anterior chamber throughout the procedure
• Protect the corneal endothelial cells from trauma
• Lubricate and assist implantation of the intraocular lens

Types of Viscoelastics

Viscoelastics are broadly divided into cohesive types such as sodium hyaluronate — easy to remove and excellent at maintaining the anterior chamber — and HPMC-based products, which are a cost-effective and safe option.

Choosing the Right One

The choice depends on the surgical technique and the surgeon’s judgment. What matters most is selecting a product that is highly transparent, sterile, and certified — for the best surgical outcome.

Browse the viscoelastics — both Sodium Hyaluronate and HPMC — imported and distributed by Japan Enterprise and certified to ISO 13485, CE and Thai FDA.
