Contemporary Eye Drop Aids
In this article, we review the benefits and limitations of 4 different devices created to make the delivery of eye drops easier.
Eyedrop medications are often used for the treatment of glaucoma and they work by lowering the eye pressure. In order for eye drops to be effective, they have to make it into the eye. Here we discuss four of these devices that make the delivery of eye drops easier and more accurate.
Autodrop is a mechanical device designed to facilitate precise eye drop delivery. It attaches to standard eye drop bottles and rests on the cheek bone, ensuring proper alignment and minimizing spillage outside the eye.
Benefits:
- User friendly
- Offers improved accuracy in eye drop delivery
- Ease of use
- Decreased risk of bottle tip contamination
- Decreased risk of injury to the eye surface from the bottle tip
Drawbacks:
- The inconvenience of an additional step
- May increase the number of drops used for some patients
Autosqueeze is another mechanical device designed to eliminate the difficulty of squeezing the eyedrop bottle. It has a central holder that attaches to standard eye drop bottles and a wing on either side. Squeezing the wings will cause the grooves on the inside of the wing to apply pressure to the eye drop bottle so that one eye drop is released.
Advantages:
- Ergonomic grip
- Helps overcome mobility difficulties
- Can be used in combination with the Autodrop
Disadvantages:
- Inconvenience of an additional step
Nanodropper is a portable attachment that reduces the size of eye drop droplets, allowing for more efficient dosing and reduced wastage. It attaches to standard eye drop bottles and dispenses smaller, more precise drops, maximizing the number of doses per bottle.
Pros:
- Precision dosing
- Improved adherence to the medication schedule
- Cost efficiency
- Decreased side effects
- Decreased waste
- Improved accuracy
Cons:
- Learning curve to using the device
- Inconvenience of an additional step
- Extending the bottle life span may increase the risk for contamination
- Its compatibility with different bottle designs may vary
GentleDrop is a nose point pivot device, where the eye drop bottle is inserted into a sleeve. That sleeve is then rested on the bridge of the nose, ensuring proper alignment.
Positives:
- Improved aim
- Minimizing waste
- Reduced risk of bottle tip contamination
Negatives:
- Incompatible with some eye drop bottles
- Inconvenience of an additional step
- May be difficult to use for patients with limited dexterity
All of these devices decrease the burden of eye drop delivery. Please discuss these with your doctor to find out which one may be most beneficial to you.
