Summary

This phase 3 study tested the long-term safety of LNZ101 eye drops, a combination of aceclidine and brimonidine, in 362 adults aged 45-75 with presbyopia (age-related blurry near vision). Participants used the drops regularly and were monitored for side effects. The study is complete, and results will show how safe the drops are for ongoing use.
