WebAlthough the major components of OPEGAN Hi 0.85 mL and Healon 0.85 mL had the same molecular weight, the extrusion force required for Healon 0.85 mL was 1.3-fold of that needed for OPEGAN Hi 0.85 mL. Since they were manufactured by different companies, the configuration of the parts of the syringe was clearly different. WebA standardized investigation to compare the biophysical characteristics of two sodium hyaluronate products, AMVISC® and Healon®, was conducted. Results showed that the two products exhibited similar biophysical properties. AMVISC® exhibited an average kinematic viscosity 6 daltons. Healon® exhibited an average kinematic viscosity 6 daltons.
WebHealon consists of very large hyaluronic acid chains with molecular weights between 2 to 5 × 10 6, and has a viscosity as high as 100 to 300 × 10 3 centistokes. One of its great advantages is that the transition from viscous to elastic behaviour occurs yet at low concentrations and at low velocities.
