Study of treatment outcomes for children with cataracts
This study looks at children who have cataracts (clouding of the eye lens) and how well treatments and eye care go. You may be able to take part if your child can cooperate with eye exams and does not have certain mental or learning conditions that affect participation.
Shanghai, Shanghai MunicipalityAges 2 months–20 years - NCT06848946RecruitingPhase 4
Eye implant with cataract surgery vs. cataract surgery alone
This trial tests if a tiny implant called iDose® TR, placed during cataract surgery, can better control eye pressure in people with glaucoma or high eye pressure compared to cataract surgery alone.
Kenosha, WisconsinAges 45 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 - NCT07246915Enrolling by invitation
Long-Term Safety of an Eye Drop for Mild to Moderate Cataract
This is a long-term follow-up study to check the safety and effectiveness of an eye drop (REVISYON SDS100) for people with mild to moderate cataract. It is only open to people who already completed the first study for this drop.
BucharestAges 40 years+ - 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 - NCT05564091Recruiting
Add a minimally invasive canaloplasty step to cataract surgery
This trial compares standard cataract surgery alone versus cataract surgery plus a procedure to improve fluid drainage in the eye. It is intended for people with mild to moderate open-angle glaucoma, to see if adding this step helps control eye pressure and preserve vision.
Sugar Land, TexasAges 55 years+ - NCT07696130Recruiting
Trifocal lens implant study for cataract or presbyopia
This study tests a new type of trifocal lens implant to see how well it improves vision at all distances after cataract or lens replacement surgery. It may help you become less dependent on glasses.
Szczecin, ZachodnipomorskieAges 50–75 - NCT06844292Recruiting
Comparing two microglaucoma surgeries with cataract surgery
This study compares two different devices (MINIject® and Hydrus® Microstent) used in microinvasive glaucoma surgery, both done at the same time as cataract surgery. It aims to find which one works better at lowering eye pressure.
Graz, StyriaAges 18 years+ - 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+ - NCT07362043Recruiting
Laser tool for cataract surgery
This study tests a handheld laser device used during cataract surgery to create a precise opening in the lens capsule. It may help surgeons improve accuracy and safety during the procedure.
Saint-HerblainAges 18 years+ - NCT07550907Recruiting
Cataract Surgery Outcomes and Surgical Technique Study
This study examines how different surgical approaches during cataract removal affect your vision and eye health after surgery. If you need cataract surgery, this trial may help doctors understand which techniques work best for patients like you.
Guangzhou, GuangdongAges 50–90 - NCT06182605Recruiting
New tools for cataract surgery
This trial is testing special tools to help doctors perform cataract surgery more safely and easily. It is for people who need cataract surgery and do not have eye inflammation, high eye pressure, or other serious health issues.
Hangzhou, ZhejiangAges 18–80 - NCT06658119Recruiting
Wide-focus lens for cataract surgery: a clinical trial
This study tests a new type of lens implant that gives you a wider range of clear vision after cataract surgery. It uses a special laser to help remove the cataract, and the lens may help you see better at near, far, and in between without glasses.
Hangzhou, ZhejiangAges 40–80 - NCT07070037Recruiting
Long-term vision after congenital cataract surgery
This study looks at how good a child's vision and eye prescription are 5 years after surgery for a cataract they were born with. The goal is to understand long-term results and help guide care for future patients.
Shanghai, Shanghai MunicipalityAges Up to 18 years - NCT07081919Recruiting
Study of laser-assisted cataract surgery outcomes
This study looks at how well femtosecond laser-assisted cataract surgery works and what factors affect its results. It may be a good option if you have age-related cataracts and regular astigmatism.
Shanghai, Shanghai MunicipalityAges 20–80 - NCT07222150Recruiting
Comparing corneal clarity and thickness in cataract patients
This study looks at how clear and thick the cornea (the clear front part of the eye) is in people with cataracts. It may help doctors understand more about eye health during cataract treatment.
Matthews, North CarolinaAges 18 years+ - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.
Sioux Falls, South DakotaAges Any age - NCT02182921Recruiting
Cataract surgery outcomes study
This study looks at how cataract surgery affects patients’ vision and recovery. You may be invited if you have cataracts and can participate in eye exams, and if mental health or thinking issues won’t interfere with the study.

- How do I know if I qualify for a cataract trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cataract trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
