On formulating ophthalmic emulsions

- Newest eye drops often contain emulsified lipids.
- Water-soluble polymers can stabilize or destabilize ophthalmic emulsions.
- Emulsions have a lower tolerance to higher molecular weight polymers.
- Polymer Mark-Houwink parameters predict emulsion stability vs Mw and concentration.
- Model can guide the formulation of ophthalmic emulsions.
