Summary

This trial will test the safety and effectiveness of a new treatment for presbyopia.

Who is the study for?
This trial is for people aged 45-64 with presbyopia, who rely on reading glasses or bifocals. They must have certain levels of visual acuity and pupil diameter, be able to self-administer medication, and attend all visits. Pregnant women, those with significant eye diseases or systemic diseases, contact lens users, and individuals allergic to the study's components cannot participate.
What is being tested?
The trial is testing the safety and effectiveness of a 0.75% phentolamine ophthalmic solution (POS) compared to a placebo in improving near vision for people with presbyopia. Participants will receive either POS or a placebo without knowing which one they are getting.
What are the potential side effects?
While specific side effects are not listed here, potential risks may include typical reactions associated with ophthalmic solutions such as eye irritation, redness, discomfort or allergic reactions. The study aims to assess these outcomes.
