Recruiting studies
- NCT07303920Recruiting
Comfort of daily disposable contacts for astigmatism over a long day
This study tests how comfortable daily disposable contact lenses for astigmatism feel when worn for a long day (like 16 hours). It may help you find a lens that stays comfortable and clear from morning to night.
Columbus, OhioAges 18–40 - NCT03299530Recruiting
Testing how corneal astigmatism measures on different settings
This study checks how accurately eye measurements describe astigmatism (a focus-bending problem) using different exam modes. It may help improve how doctors assess astigmatism after cataract surgery so treatment planning is more precise.
Wenzhou, ZhejiangAges 18 years+ - NCT07722247Recruiting
Eye stiffness and healing in cataract surgery with PEX
This study looks at how your eye's outer layer (cornea) heals and changes shape after cataract surgery, specifically comparing people who have pseudoexfoliation syndrome (PEX) with those who do not. The goal is to see if PEX affects the final vision result after cataract removal.
Split, Splitsko-dalmatinska CountyAges 50–85 - NCT06694051Recruiting
Light treatment to mark astigmatism axis
This trial uses a special laser treatment to mark the exact axis of astigmatism for better correction. It might help patients with astigmatism get more precise treatment.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT07605221Recruiting
Testing a formula for laser eye surgery astigmatism correction
This study develops a formula to help surgeons correct astigmatism (blurred vision from curved corneas) during a laser eye surgery called LASEK. If you're eligible, your surgery may be more precisely tailored to your eye shape.
Tianjin, Tianjin MunicipalityAges 18–45 - NCT07294716Recruiting
New lens for cataract patients with irregular corneas
This trial tests a special type of lens implant (asymmetric toric intraocular lens) for people having cataract surgery who also have an irregularly shaped cornea. The goal is to see if this lens can improve the quality of your vision after surgery.
LinzAges 21 years+ - NCT07201298Recruiting
Comparing laser eye surgery methods for nearsightedness
This study compares a new type of laser surgery (ray-tracing guided) to three other standard laser methods for correcting nearsightedness with or without astigmatism. It aims to see which approach provides the best vision correction.
Draper, UtahAges 22–50 - NCT07140653RecruitingPhase 4
Adjustable lens with corneal cuts for astigmatism during cataract surgery
This study tests whether combining tiny corneal cuts with a special adjustable lens can better correct astigmatism (an irregularly shaped cornea) during lens replacement surgery. It may help people who need cataract surgery and have astigmatism achieve sharper vision without glasses.
Venice, FloridaAges 21 years+ - NCT04251143Recruiting
Study for corneal disease and corneal thinning
This study looks at people with corneal disease, especially corneal thinning that can change how the eye focuses light. It may help researchers understand treatments and care plans for these conditions.
Dresden, SaxonyAges 18–65 - NCT05486546Recruiting
Compare two LASIK mapping methods for myopia and astigmatism
This trial compares two ways of mapping your eye to guide LASIK surgery for people with nearsightedness and mild astigmatism. It looks at how well vision (especially best-corrected vision) does after surgery one month later.
Bozeman, MontanaAges 21–38 - NCT06059521Recruiting
Comparing a mobile vision test to standard eye exams
This trial tests a new way to measure your eyeglass prescription using a mobile device, compared with a traditional method called retinoscopy. It may help you get a quick and accurate vision check without needing special equipment.
Beijing, Beijing MunicipalityAges 10–46 - NCT07790185RecruitingPhase 4
LASIK for nearsightedness: measuring vision and satisfaction
This study tests how well a new type of LASIK (called ray-tracing-guided) improves vision in low light and how satisfied patients are with the results. It is for people with mild to moderate nearsightedness who want to stop wearing glasses or contacts.
Sioux Falls, South DakotaAges 18–45 - NCT07721714RecruitingPhase 4
Comparing two types of laser eye surgery for nearsightedness
This trial compares two laser vision correction methods: SMILE surgery in one eye and LASIK surgery in the other eye. It is designed for people with mild to moderate nearsightedness and astigmatism to see which approach works better.
Palo Alto, CaliforniaAges 22–59 - NCT02576483Recruiting
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.
Palo Alto, CaliforniaAges 21–62 - NCT07657858Recruiting
Does Dry Eye Treatment Affect Astigmatism Measurements Before Cataract Surgery?
This study checks whether treating dry eyes before cataract surgery can change the way your eye's shape (astigmatism) is measured. It may help make your surgery more accurate.
Shanghai, Shanghai MunicipalityAges Any age - NCT07502456Recruiting
Clareon TruPlus study for cataract patients with astigmatism
This trial tests a new type of lens (toric IOL) to correct both cataracts and astigmatism in one surgery. It may help you see clearly without glasses if you have cataracts and a mild to moderate astigmatism.
Phoenix, ArizonaAges 22 years+ - NCT06839898Recruiting
Study of two implantable astigmatism-correcting lenses
This study tests two types of implantable lenses that correct astigmatism (blurry vision from an irregularly shaped cornea). You keep your own natural lens, and the new lens is placed in front of it—no laser or lens removal needed. The goal is to see which lens works better and is safer.
Münster, North Rhine-WestphaliaAges 21 years+ - NCT07232615Recruiting
Comparing two types of trifocal lenses for cataract surgery
This study compares two different trifocal toric intraocular lenses (special lenses that correct both near, far, and astigmatism) used during cataract surgery. Researchers want to see which lens gives better results for people with cataracts and astigmatism.
Düsseldorf, North Rhine-WestphaliaAges 21 years+ - NCT07198126Enrolling by invitation
How pterygium surgery changes corneal curvature in astigmatism
This trial compares how the curve of your cornea (which affects vision) changes before and after surgery to remove a pterygium—a fleshy growth on the eye—and repair the area with your own tissue. It is for adults with moderate to advanced pterygium that has already caused astigmatism.
Lahore, Punjab ProvinceAges 30–70 - NCT06882408Recruiting
Vision screening study for children
This study tests a special camera that checks for vision problems in children. It is designed to find nearsightedness, farsightedness, and other eye issues. Kids will have a quick vision check during one visit.
Nancy, FranceAges 3–8 - NCT07127757Recruiting
New laser vision correction study for nearsightedness
This study tests a newer version of LASIK eye surgery to correct nearsightedness and astigmatism. The researchers want to see if this laser approach is safe and effective for people who are eligible.
Greensboro, North CarolinaAges 18 years+ - NCT03803852Recruiting
Testing different toric lens types during cataract surgery
This study compares different types of artificial lens implants (including toric lenses that correct astigmatism) during cataract surgery. It may help find which lens options work best for your vision and astigmatism correction.

Common questions
- Are there clinical trials for astigmatism?
- Yes. Clin2 currently lists 30 recruiting astigmatism studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a astigmatism 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 astigmatism 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.
