Most patients don’t realize that nearly 80% of every eyedrop is wasted—either rolling down the cheek or draining into the tear ducts where it’s absorbed into the body instead of treating the eye. This post would educate patients and providers about the hidden problems with oversized drops and how Nanodropper addresses them.
- The Problem with Oversized Drops
-
-
Commercial bottles dispense ~30–50 µL per drop.
-
The eye can only hold 7–10 µL at a time.
-
That means 70–80% of the medication is wasted with every single drop.
-
-
The Financial Burden
-
Glaucoma patients often take 2–3 different medications per day.
-
Bottles run out early, creating refill stress, insurance hassles, and hundreds to thousands of dollars in annual costs.
-
Even patients with “good insurance” face high copays on branded drugs.
-
-
The Health Risks
-
Excess fluid increases systemic absorption (through tear ducts), raising risks of side effects from drugs like beta-blockers (lowered heart rate, fatigue).
-
Overflowing drops can cause dermatitis on the skin around the eyes (red, itchy, swollen lids).
-
Higher preservative load per dose = more irritation and dry eye symptoms.
-
-
The Environmental Cost
-
Unused medication = wasted manufacturing, shipping, and disposal.
-
More bottles consumed = more plastic waste in healthcare.
-
-
