Chemical names (brand names)ViscosityComposition

Cohesive (Opegan Hi®)Intrinsic viscosity 25∼45 (dL/g)1% sodium hyaluronate
Dispersive (Shellgan®)35000∼60000 mPa s (25°C, shear rate 2/s)3% sodium hyaluronate
4% chondroitin sulfate sodium
Viscoadaptive (Healon5®)Zero shear viscosity: about 7 million (mPa s)23% sodium hyaluronate
Viscous dispersive (DisCoVisc®)Viscosity (shear rate 1/s, 25°C): 75000 ± 35000 (mPa s)1.65% sodium hyaluronate
4% chondriotin sulfate sodium
