Comparing two types of LASIK for nearsightedness and astigmatism
This study compares two types of LASIK surgery to correct nearsightedness and astigmatism. It may help if you have healthy eyes, are 22 or older, and have a stable prescription within a certain range.

Comfort and vision with TOTAL30 multifocal lenses
This trial tests how comfortable and clear your vision is with TOTAL30 multifocal contact lenses. If you already wear multifocal soft lenses and are 40+, you may qualify to help understand how these lenses perform in daily life.

Compare LASIK, SMILE, and PRK for eye prescription correction
This study compares three laser eye surgeries—LASIK, SMILE, and PRK—to see which works best for people who have similar eye prescription needs. You may be a good fit if you’ve never had vision-correcting surgery before and you meet the eye-health safety checks.

What taking part in a astigmatism study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there astigmatism clinical trials in California?
- Yes. We're currently tracking 4 recruiting astigmatism studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a astigmatism study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a astigmatism trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
