Nomogram for Astigmatism Correction of KLEx
China100 participantsStarted 2025-02-18
Plain-language summary
The goal of this clinical trial is to learn if nomogram could promote treatment outcomes in astigmatism correction. The main question it aims to answer is:
does the nomogram could promote treatment outcomes in astigmatism correction? If there is a comparison group: Researchers will compare non-nomogram adopted to see if the outcome acceptable.
Participants will ask to complete 3-month follow-up of manifest refraction and visual acuity test.

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 studying a nomogram to improve astigmatism correction with LASEK — how does a nomogram work, and why might my current treatment plan benefit from this kind of adjustment?
2Since this trial is listed as Phase NA and is focused on measuring residual astigmatism after the procedure, what does that mean for what's already known about the safety and effectiveness of this specific approach?
3If I join this study and still have residual astigmatism after my LASEK procedure, what options would be available to address that, and would the trial cover any follow-up treatment?
4How does the correction accuracy being studied in this trial compare to what I could expect from a standard LASEK procedure performed outside of a research setting?
5Given that this trial is actively recruiting, what would my time commitment look like in terms of visits and follow-up appointments, and how might that fit into my schedule?

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?
