Study Summary

This trial studied the safety of a drug for long-term use to help with presbyopia (age-related vision problems).

Who is the study for?
This trial is for people aged 45-75 with presbyopia, a condition affecting near vision. Participants must have specific levels of visual acuity (+1.00 to -4.00 diopters) and be willing to follow the study's procedures. Pregnant or nursing women, those planning pregnancy, or individuals with known sensitivities to study medications, active eye infections, severe dry eye, or significant lens abnormalities cannot join.Check my eligibility
What is being tested?
The trial tests the long-term safety of LNZ101 in treating presbyopia by comparing an Aceclidine+Brimonidine combination solution against a placebo and Aceclidine alone. The goal is to see if these treatments can safely improve near vision without serious side effects.See study design
What are the potential side effects?
Potential side effects may include reactions at the site of application (eyes), such as redness, discomfort or itching; systemic effects could involve headache or fatigue. Specific side effect profiles will be monitored closely throughout the study.
