Challenges such as accurately aiming drops, discomfort caused by contact between the bottle tip and the eye, and waste of medication often lead to reduced adherence to treatment regimens and less than optimal outcomes for many glaucoma patients. In response to these issues, innovators have developed various solutions. Here is a brief description of three devices designed to improve the accuracy and comfort of self-administered eye drops.*

GentleDrop

Developed by ophthalmologists, the GentleDrop is a silicone device designed to assist patients in positioning their eye drop bottles effectively. It expands to fit most eye drop bottles, optimizes bottle position, and prevents the bottle tip from contacting the eye. 

A study comparing the GentleDrop with traditional delivery techniques found that patients preferred the GentleDrop, resulting in higher ease of use scores and fewer instances of the bottle tip touching the eye.

Nanodropper

The Nanodropper is an adapter made of soft silicone that attaches to standard eye drop bottles. It features an elongated tip to help users hold the bottle farther from the eye and aim drops more accurately. To use, patients remove the original bottle cap and attach the Nanodropper.

By reducing drop size by more than 60%, the Nanodropper aims to minimize wastage, side effects, and costs associated with eye drop use.

Optejet Dispenser

Eyenovia’s Optejet dispenser by Eyenovia uses Microdose Array Print technology to deliver medication horizontally as a directional mist in microdroplets. This method reduces exposure to drug and preservative toxicity by 80% compared to traditional eye drops. 

The Optejet dispenser is being investigated for various eye conditions, including myopia, presbyopia, and mydriasis.

Other eye drop aids

These are just a few of the devices available on the market. Others include the Eye Drop Hero brand eye drop guide, the Easy Eye Drop eye drop glasses, the Remedic reusable eye drop dispenser, and the Easy Comfort eye drop guide.
