I am a silent member and can answer your question about the individual vials. They are ok to use up to 18-24 hrs after opening as long as you don't touch the tip to any thing. My mom's a newly diagnosed pd case,and I recently had eye surgery and that was my docs instructions on the eye drops. nancy y
