New Eye Drops Show Promise for Restoring Close-Up Vision

As people age, many face presbyopia, which makes it tough to read things clearly up close. Traditionally, reading glasses have been the go-to solution. However, a recent study hints at some exciting alternatives.

Researchers have found that specially formulated eye drops may help restore near vision for many individuals, providing a non-invasive option for dealing with age-related vision changes. This research was shared at the 43rd Parliament of the European Association of Denmark and the Association of Refractive Surgeons on September 14, involving 766 participants who displayed typical symptoms of presbyopia.

Instead of resorting to glasses, participants received eye drops containing pilocarpine—a drug that aids focusing—and diclofenac, a mild anti-inflammatory meant to enhance comfort during the treatment.

Dr. Giovanna Benozzi, who leads the Elders Research Centre in Buenos Aires, noted that the study was driven by the need for better solutions for managing vision issues in older adults. “Current options like glasses or surgery come with limitations—sometimes awkward or even risky,” she explained.

Participants were instructed to use the eye drops twice daily—once in the morning and again about six hours later. They could also take a third dose if necessary. Over two years, their vision was regularly assessed using a small print eye chart.

Results showed that within an hour of their first dose, many could read several additional lines on the chart. With the lower concentration of drops nearly all participants experienced at least two additional lines of clarity, while a stronger formulation allowed many to read more than three extra lines.

Over 80% of participants maintained the improvements in vision after a year of consistent use without needing glasses, and for some, these benefits lasted beyond a year.

While side effects were limited—about one-third of participants noticed some minor blurriness—very few reported headaches or other discomforts, and these did not lead to any drop in usage.

Dr. Benozzi emphasized that the aim was to offer a simple alternative rather than to replace surgical options. “This treatment allows for more flexibility, and it helps many avoid constantly reaching for their reading glasses,” she said.

That said, experts caution that further research is necessary before these drops can be recommended widely. The study was conducted at a single center, meaning the findings might not be applicable to all demographics.

Pilocarpine has been utilized in various eye treatments for a long time, but long-term daily usage raises concerns, such as potential poor night vision or more severe retinal issues. Likewise, prolonged use of diclofenac could affect the surface of the eye, warranting careful attention going forward.

External researchers acknowledge the promising nature of these findings but stress the need for larger, multicenter clinical trials that follow participants for more extended periods to establish long-term safety and efficacy.
