Recruiting studies
- NCT04205916RecruitingPhase 4
Preference trial of eye drops versus no-drops after cataract surgery
This trial compares two ways to prevent inflammation and comfort you after cataract surgery: usual antibiotic/steroid eye drops versus a “no-drops” option that is placed during surgery. It mainly looks at patient preference, comfort, and ease of treatment after surgery.
Garden City, New YorkAges 22–100 - NCT04651530Recruiting
Endoscopic laser treatment for normal-pressure glaucoma
This study tests an endoscopic laser procedure to lower eye pressure and slow damage in people with normal-tension glaucoma. It may help protect the optic nerve, especially if your glaucoma is stable on drops and you also have a cataract.
HelsinkiAges 55–100 - NCT04833491Recruiting
Eye measurements before cataract surgery and vision quality after
This study uses very specific eye measurements done before cataract surgery to see how they relate to the clarity of vision after surgery. It may help surgeons choose the best surgical approach and improve visual outcomes.
HangzhouAges 2–90 - NCT05136209Recruiting
Surgery for children’s cataracts: with or without vitrectomy
This trial compares two surgical techniques to treat cataracts present since birth in children, to see which approach works better. It may help your child by improving surgical outcomes and recovery.
Guangzhou, GuangdongAges 1 month–18 years - NCT03455478Recruiting
Study of adult vision health in Shanghai residents
This study looks at the eye health of adults who live in Shanghai. It may help researchers understand vision problems in the local population and improve future eye care.
Shanghai, Shanghai MunicipalityAges 18–100 - NCT06053554Recruiting
Comparing two cataract surgery methods for pseudoexfoliation
This study compares two different surgical methods for placing a new artificial lens (IOL) during cataract surgery in people with pseudoexfoliation syndrome. It aims to find which method works best for these patients.
ViennaAges 60–100 - NCT07825337Recruiting
Futuristic headset to help surgeons see during eye surgery
This study tests whether a futuristic headset that projects digital information can help surgeons see better during eye surgery. You may be able to participate if you are having a standard eye procedure and have no other eye problems that could make surgery riskier.
Brentwood, New YorkAges 18–90 - NCT07796178RecruitingPhase 4
Dry eye relief and comfort after cataract surgery
This study tests a treatment called Lacrifill to see if it helps reduce dry eye symptoms after cataract surgery. You would receive the treatment after your surgery to see if it improves comfort and eye health.
Pittsburg, KansasAges 18–80 - NCT07740590Recruiting
Comparing artificial lenses for cataract surgery and quality of life
This study compares different types of artificial lenses (IOLs) placed during cataract surgery to see which helps your eyes adapt and improves your quality of life best. It is for people having cataract surgery on both eyes who have very little natural corneal curve (astigmatism).
ChengduAges 18–100 - NCT06625749Recruiting
AccuraSee lens implant to improve near vision after cataract surgery
This trial tests an artificial lens (AccuraSee IOPCL) placed inside your eye to help you see better up close and at intermediate distances after having cataract surgery. It is for people who still need reading glasses and have a specific type of monofocal lens already in their eye.
Cleveland, OhioAges 22 years+ - NCT06624826Recruiting
Extended depth of focus lens for cataract surgery
This study tests a new type of lens implant that helps you see clearly at multiple distances after cataract surgery. It compares two ways to set the lens: one aiming for perfect distance vision in both eyes, and another that leaves one eye slightly nearsighted to improve reading vision.
Vienna, AustriaAges 21–105 - NCT07693829Recruiting
Smart bed-exit alert for cataract surgery patients
This trial tests a smart bed-exit alert device to help detect when patients get out of bed before eye surgery. It aims to improve safety in the operating room.
TaipeiAges 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 - 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+ - 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+ - 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+ - NCT07610226Recruiting
Cataract Surgery Lens for Prior Myopic Eye Surgery
This study tests a special intraocular lens (an artificial lens implanted during cataract surgery) designed for patients who had prior myopic refractive surgery (LASIK or PRK to correct nearsightedness). The goal is to achieve the best possible vision correction after cataract removal.
Greensboro, North CarolinaAges 18 years+ - NCT06201455Recruiting
Glaucoma surgery study for people with controlled eye pressure and cataracts
This study tests a new surgery that combines cataract removal with a glaucoma procedure to lower eye pressure in people with primary open-angle glaucoma. It's for people whose eye pressure is controlled with 1 to 4 medications but who also have significant cataracts.
Guangzhou, GuangdongAges 40–85 - NCT06754358RecruitingPhase 1
Comparing two laser systems for cataract surgery
This study compares two types of femtosecond lasers used during cataract surgery. It is for people of Chinese Han ethnicity who are 40 or older and have age-related cataracts.
Hangzhou, ZhejiangAges 40 years+ - 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 - NCT07471295RecruitingPhase 4
Study of a toric lens for cataract with astigmatism
This study tests a special lens implant (toric lens) for people having cataract surgery who also have astigmatism. The lens corrects both the cataract and the astigmatism, potentially giving you clearer distance vision without glasses.
Prague, PragueAges 18 years+ - 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+ - NCT06801678Recruiting
Comparing two eye measurement devices for cataract surgery
This trial tests two different devices that measure your eyes before cataract surgery to see which one helps doctors choose the best lens implant. The goal is to get your vision as close to perfect as possible after surgery.
