Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is comparing multifocal contact lenses to single vision lenses with reading glasses — based on my current prescription and how my presbyopia affects me day to day, which of those two options does my doctor think would suit my lifestyle better before I consider joining a preference study like this?
2Since this is a Phase NA study measuring preference through a survey rather than testing a new medical treatment, what does my doctor think I'd actually be asked to do during the trial, and how much of my time would it realistically take?
3The trial is currently recruiting — are there any vision, health, or lifestyle requirements I should know about that might affect whether this study is even worth discussing with my care team?
4If I try multifocal contact lenses as part of this study and don't get on well with them, would I be able to go back to my current correction method without any lasting impact on my vision or prescription?
5Could my doctor walk me through whether joining this trial would delay or replace any standard presbyopia treatment options I might otherwise start now, or whether I could pursue those at the same time?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
