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.
1Since this trial is not yet recruiting, do you know when it might open and whether it would still be relevant to my cataract surgery timeline?
2This study is looking at whether dry eye disease affects how accurately doctors can calculate the right lens power before cataract surgery — do you think my dry eye status could be affecting the lens measurements you're taking for me right now?
3If dry eye disease can throw off intraocular lens power calculations, is there anything we should do to treat or stabilize my dry eye before you take my pre-surgical measurements?
4This trial is observational and focused on measuring error rates rather than testing a new treatment — does that mean there's no experimental procedure involved, and what would actually be expected of me if I participated?
5Are there existing guidelines or evidence you already use to account for dry eye when calculating my lens power, or is this still an open question in your clinical practice?

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
