Researchers conducted a small study to see if using a microdrop device called Nanodropper could work as well as regular eye drops for people with glaucoma. They studied 29 adults who already had stable glaucoma or high eye pressure and were using just one type of medication. Each participant tried both the microdrop method and conventional drops for 12 weeks each, in a random order.
The study found that using microdrops lowered eye pressure by about 1.6 mm Hg from where patients started, while conventional drops showed almost no change. More importantly, the microdrop method dramatically reduced how often bottles ran out early—from happening to 83% of people with conventional drops down to just 17% with microdrops. People also reported fewer side effects like eye irritation with the microdrop device.
It's important to be careful with these results. This was a small study at just one clinic, looking only at people whose condition was already stable on one medication. Each treatment period lasted only 12 weeks, which is relatively short for a chronic condition like glaucoma. While the device shows promise for reducing waste and side effects, larger and longer studies in more diverse groups of patients are needed before we know how well it works for everyone.
