eBook: Viscosity of Eye Drops

Dry eye, a medical condition that is associated with a lack of lubrication on the eye surface, s a chronic problem for many people. There is currently a variety of eye drops formulated to treat dry eye symptoms on the market. Each different eye drop or brand has it's own unique formulation and different major formulation component(s).

Viscosity is one essential parameter to factor in when formulating eye drops. Viscosity and its shear rate dependence directly impact the performance of eye drops formulated for the relief of dry eye. Viscosity impacts both the retention of the drops when inserted in the eyes and the performance through the blink cycle. Knowing the formulation viscosity in this regime is crucial to predicting performance.
