Healon®5: A New Viscoadaptive Formulation

2000

To relate the practical relevance of our study results, specific requirement profiles for individual procedures have been correlated to the desired physicochemical characteristics. Healon®5 demonstrated the statistically significant highest zero shear viscosity of all OVD and a long relaxation time (Dick et al., 2000). It therefore most effectively creates and maintains a deep anterior chamber in order to facilitate safe surgical maneuvers (e.g., in case of vitreous pressure). Additionally, the high viscosity of Healon®5 exhibits a dynamic frequency dependence, which has not been observed in any pure hyaluronic acid formulation before. Healon®5’s properties change in response to surgical ma…
