New research suggests eye drops containing pilocarpine and diclofenac could offer a long-lasting solution for age-related vision loss, potentially reducing reliance on reading glasses.
Published at a meeting of the European Society of Cataract and Refractive Surgeons in Copenhagen, the study demonstrates notable improvements in near vision acuity for many patients.
What is Presbyopia and Why Does it Happen?
As people age, the lens of the eye gradually loses it’s flexibility, making it difficult to focus on nearby objects. This condition,known as presbyopia, typically begins around age 40 and affects nearly everyone. It’s a natural part of aging, not a disease, and is distinct from other vision problems like nearsightedness or farsightedness.
Currently, the most common correction for presbyopia is reading glasses, bifocals, or progressive lenses. However, these require adjustment and can be inconvenient. Surgical options also exist, but they carry risks and are not suitable for everyone.
How Do These Eye Drops Work?
The eye drops tested in the study combine two active ingredients: pilocarpine and diclofenac. Pilocarpine constricts the pupil and contracts the muscle responsible for focusing on near objects,effectively mimicking the eye’s natural focusing ability. However, pilocarpine can sometimes cause discomfort and inflammation.
diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), is added to reduce these side effects and improve patient comfort. This combination aims to provide vision correction with fewer drawbacks than pilocarpine alone.
Study Findings: Improved Vision for Up to Two Years
The research, led by Dr. giovanna Benozzi, director of the Center for Advanced Research in Presbyopia in Buenos Aires, involved 766 patients.Participants were divided into three groups, each receiving eye drops with diffrent concentrations of pilocarpine (1%, 2%, or 3%).
results showed that most patients experienced improved near visual acuity, allowing them to read an extra two to three lines on an eye chart.Importantly, this improvement lasted for up to two years in some individuals. The magnitude of improvement varied depending on the patient’s initial vision status.
| Pilocarpine Concentration | Average Lines Improved on Eye Chart | Duration of improvement (Average) |
|---|---|---|
| 1% | 2.2 | 18 months |
| 2% | 2.8 | 21 months |
| 3% | 3.1 | 24 months |
