Cataract Surgery clinical trials in California
We’re tracking 8 recruiting cataract surgery studies with a site in California — including Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT07715591Recruiting
Relaxing breathing during awake cataract surgery
This study tests a special breathing and pain education program to help you stay calm and comfortable during cataract surgery while you are awake. It may reduce pain and anxiety without extra medicine.
Los Angeles, CaliforniaAges Any age - NCT05980117RecruitingPhase 4
Remimazolam sedation for cataract surgery
This study tests a sedative, remimazolam, for older adults having their first cataract surgery. It aims to see if it helps keep patients comfortable and calm without needing general anesthesia.
Los Angeles, CaliforniaAges 65 years+ - NCT07468877Recruiting
Comparing two cataract surgery systems for bilateral cataract removal
This trial compares two machines used during cataract surgery to see which one uses less energy and ultrasound time. If you are healthy and need cataract surgery in both eyes, this study might help determine the best approach.
Los Angeles, CaliforniaAges 18 years+ - NCT07589894Enrolling by invitation
Vision outcomes after cataract surgery with TruPlus lenses
This study measures how well people see after cataract removal surgery using a special TruPlus intraocular lens (an artificial lens placed in the eye). Researchers want to understand if this lens helps patients see clearly at distance with minimal side effects.
Encino, CaliforniaAges 50–80 - NCT07317661Enrolling by invitation
LLM-based app for cataract lens choice education
This trial studies whether a large language model (an AI tool) can help explain intraocular lens options to patients before cataract surgery. If you're planning your first cataract surgery, you may be able to join.
Palo Alto, CaliforniaAges 18 years+ - NCT05157113RecruitingPhase 4
After cataract surgery, a drop-free medicine plan
This trial studies whether a “drop-free” medication plan after cataract surgery works well and is practical for people receiving care at a county hospital. It may help reduce the need for multiple eye drops after surgery while still protecting the eye as it heals.
San Francisco, CaliforniaAges 18 years+ - NCT05191706RecruitingPhase 4
Check how safe DEXYCU is after childhood cataract surgery
This trial studies whether DEXYCU is safe to use to reduce eye inflammation after cataract surgery in children. It aims to see if the medicine’s side effects are acceptable and whether it helps during normal recovery.
Huntington Beach, CaliforniaAges Up to 3 years - NCT04553523Recruiting
Hydrus microstent study for open-angle glaucoma with cataracts
This study enrolls people who have cataracts and primary open-angle glaucoma that is being treated with eye drops. It will look at how well the Hydrus microstent works after approval, especially for lowering eye pressure safely.

What taking part in a cataract surgery 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 cataract surgery clinical trials in California?
- Yes. We're currently tracking 8 recruiting cataract surgery 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 cataract surgery 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 cataract surgery 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.
Not the right time?
New cataract surgery studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
