Product Overview
Singclean® Viscoelastic Solution is a medical sodium hyaluronate gel designed for ophthalmic surgery. It is known for its high viscoelasticity, good cohesion, safety, and biocompatibility. The product is used to aid in anterior or posterior segment ophthalmic surgeries, such as cataract extraction, corneal transplant surgery, glaucoma filtering surgery, and secondary lens implantation.

Specifications and Composition
The solution is a clear liquid gel composed of sodium hyaluronate and physiological balancing salt. It has a concentration of 15mg/mL and is available in volumes of 0.5mL, 0.75mL, 1.0mL, and 2.0mL. The high molecular weight (1,000,000~2,600,000 Daltons) and shear viscosity (≥100,000 mPa-s) contribute to its effectiveness in maintaining the depth of the anterior chamber during surgery.

Installation and Usage Instructions
The product comes with a syringe fitted with a needle. Installation involves removing the tip cap, inserting and tightening the blunt needle, and removing the needle cap. Before use, air should be expelled from the needle, and the solution should be injected appropriately into the eye by trained specialists. Care should be taken to avoid over-tightening the needle and applying excessive force on the plunger.

Advantages
Singclean® is derived from non-animal sources through bacterial fermentation, ensuring no pyrogen or rejection reactions. It is terminally sterilized and filled using automated machinery for high cleanliness and transparency. The product's high viscoelasticity and cohesion make it suitable for stable surgical operations.
