As age progresses, many people develop presbyopia – age-related hyperopia makes reading things difficult at close range – and may turn to reading glasses. However, new research suggests that alternative options may be on the horizon.
Scientists can discover that specially formulated eye drops can restore close-up visions in many patients, providing an age-related, non-attractive, non-glass approach Loss of vision.
The study was presented at the 43rd Parliament of the European and European Association of Denmark and the Association of Refractive Surgeons on September 14, following 766 patients, most experienced classic symptoms of presbyopia.

Instead of glasses, researchers prescribed drops containing pilocarpine Useful medicines The eyes adjust the focus along with diclofenac, a mild anti-inflammatory agent designed to make treatment more comfortable.
Dr Giovanna Benozzi, director of the Elders Research Centre in Buenos Aires, Argentina, said in a press release that the team conducted the study because of unmet medical needs in the management of elders.
“Current solutions such as reading glasses or Surgical interventionthere are limitations such as inconvenience, social discomfort, potential risks and complications,” she said.
Patients were instructed to use the drops again twice daily, once in the morning, approximately 6 hours later, with a third dose selected as needed. Their eyesight was then measured on a small print eye chart over two years.

Within an hour of application Initial dosagethe patient was able to read quite a few lines on the myopia chart, the researchers found.
At the lowest concentration of drops, almost all participants were able to see at least two extra lines, but the stronger formulation gave many the ability to read more than three.
After a year of daily use, over 8 in 10 patients still enjoyed improving their vision without relying on glasses. For many, profits lasted more than a year.
Side effects were relatively minor, the researchers reported. Approximately one-third of participants noticed a short harmony in their vision, but a small number reported mild stimulation. Or a headache.
Due to these issues, no patients stopped using the drop because of these issues.
Benozzi, who led the research, said that treatment was not possible. Please replace the surgery For those who want a permanent fix, but rather offer an accessible, non-invasive alternative.
“This will give patients flexibility and not spare many people as they have to constantly reach for their reading glasses,” she added.
Still, experts warn that more work needs to be done before drops become mainstream. This study was conducted in a single center. In other words, the outcome may not apply to all populations.

Pilocarpine is used elsewhere Eye treatment For decades, long-term daily use raises questions about potential side effects, such as reduced night vision and more severe retinal problems.
Extended use of diclofenac can pose a risk to the surface of the eye, an area that requires further monitoring, experts warn.
External researchers say the findings are promising, but highlight the need for a larger multicenter Clinical trials The follow-up period is long.
