Recruiting studies
- NCT07325162Recruiting
New eye scanner for cataract patients
This study is testing a new optical device that measures the eye before cataract surgery. It may help doctors get more accurate measurements for your lens implant.
Hilton Head Island, South CarolinaAges 18 years+ - NCT07325188Recruiting
Smart Guide for Toric Lens Positioning in Cataract Surgery
This trial tests a new guidance system to help doctors place toric lenses more accurately during cataract surgery. It may help people who need a toric lens to correct astigmatism.
Gainesville, GeorgiaAges 18 years+ - NCT00532051Recruiting
Test eye scans to choose the right cataract lens power
This study is looking at how special eye scans (optical coherence tomography, or OCT) can help doctors calculate the correct power of a cataract lens after you’ve had laser vision correction before. It may help improve how well your new lens matches your eye after prior laser treatment.
Portland, OregonAges 18 years+ - NCT02678962Recruiting
Multifocal lens eye surgery: compare results in both eyes
This trial compares outcomes from multifocal intraocular lenses (artificial lenses that help with focusing) after cataract surgery on both eyes. It may help show whether these lenses give better vision compared with other expectations after surgery.
Wenzhou, ZhejiangAges 40–80 - NCT01654159Enrolling by invitation
Study of vision and lens optics during cataract surgery
This study looks at how well your vision works and how different cataract surgery lens choices perform. It may help researchers better understand what affects sight after cataract surgery.
Birmingham, West MidlandsAges 40–85 - NCT07425496Recruiting
Eye fluid dynamics study during surgery
This trial measures eye fluid flow during cataract or glaucoma surgery. It aims to help doctors predict and improve surgery results.
New York, New YorkAges 18 years+ - NCT07436247Recruiting
Measuring vision and eye shape after cataract surgery
This study tests new ways to measure how well your eye sees after having cataract surgery with a special lens that helps with reading and distance. They'll take detailed measurements of your eye to improve future lens designs.
ViennaAges 21–110 - NCT07453992Recruiting
Comparing three toric lenses for cataract and astigmatism
This study compares three types of toric lenses (lenses that correct both cataracts and astigmatism) to see how well they stay in place after surgery. It may help you choose the best lens for your cataract surgery.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07609186Recruiting
Sound therapy during cataract surgery in older adults
This study tests whether listening to special binaural sounds (through earphones) during cataract surgery helps older patients stay calm and comfortable. The surgery uses light sedation, and researchers want to see if the sounds improve the experience.
SeoulAges 65 years+ - NCT07634913Recruiting
Mobile App for Eye Disease Detection
This study tests a smartphone-based system designed to help detect diseases affecting the front of the eye. Researchers will develop and refine this mobile tool to see if it can accurately identify common eye conditions using photos taken on a phone or with standard eye-examination equipment.
Guangzhou, GuangdongAges 18 years+ - NCT07648355Recruiting
Vision outcomes with Clareon TruPlus lens implants
This study tests a new type of lens implant (Clareon TruPlus) used during cataract surgery. Researchers will measure how well patients see afterward and how satisfied they are with their vision.
Saint Louis Park, MinnesotaAges 18 years+ - 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 - NCT07480343Enrolling by invitation
Five-year follow-up after CREST glaucoma study
This study follows up with people who finished the CREST study to check how their eyes are doing 5 years later. It looks at the long-term results of a prior glaucoma treatment.
Newport Beach, CaliforniaAges Any age - NCT07076277Enrolling by invitation
Comparing vision after different cataract lens implants
This study compares two types of advanced artificial lens implants used during cataract surgery. It looks at how well people see after getting one type of lens in one eye and the other type in the other eye, compared to getting the same type in both eyes.
Baltimore, MarylandAges 18 years+ - NCT07073937Enrolling by invitation
Three-year results of combined microstent and canaloplasty surgery
This trial is checking how well a combined eye surgery (Hydrus microstent plus canaloplasty plus cataract surgery) works over 3 years. It looks at long-term safety and effect on eye pressure. It's for people with open-angle glaucoma who already had that specific combination of procedures.
Salt Lake City, UtahAges 18 years+ - NCT07007897Enrolling by invitation
Cataract treatment observation study
This study is for people with cataracts who are planning to get treatment. It will observe your eye health and treatment process without giving you any new medicine.
Mesa, ArizonaAges 21 years+ - NCT06969586Enrolling by invitation
Eye drops study for Fuchs corneal disease and glaucoma
This study tests whether special eye drops (Rho-kinase inhibitors) can improve the health of the cornea in people who have both Fuchs endothelial corneal dystrophy and glaucoma. The drops may help reduce corneal swelling and preserve your vision.
ZagrebAges 40–90 - NCT06650358Enrolling by invitation
Outcomes for patients with LAL+ lens implants
This study looks at how the LAL+ lens implant performs in people who have had cataract surgery in both eyes and have completed light adjustments for the LAL+ lens. It aims to gather information on vision results and safety.
Wilkes-Barre, PennsylvaniaAges Any age - NCT06649799Enrolling by invitation
Comparing two lasers for cataract surgery in older adults
This study tests two different femtosecond lasers (LenSx and Z8) used during cataract surgery to see how they affect the eye's natural response, including inflammation and pupil size. It is designed for adults over 50 with age-related cataracts of moderate hardness.
Hangzhou, ZhejiangAges 50–80 - NCT06578884Enrolling by invitation
Testing a new toric lens for cataract and astigmatism
This study tests a new toric intraocular lens (a replacement lens for the eye) designed to fix both cataracts and corneal astigmatism (an uneven cornea that blurs vision). If you are planning cataract surgery or a lens exchange and have astigmatism that needs correcting, this lens may be an option for you.
GyőrAges 18 years+ - NCT06056154Enrolling by invitation
Testing a new artificial lens for cataract surgery
This trial tests a new type of artificial lens (called Asqelio Monofocal) for people having cataract surgery. The lens is designed to give clear distance vision without glasses.

Common questions
- Are there clinical trials for cataract?
- Yes. Clin2 currently lists 165 recruiting cataract 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 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.
