Guangzhou, GuangdongAges 50–80 - NCT07347379Enrolling by invitation
Long-term follow-up for people with the light adjustable lens
This study checks how well the light adjustable lens (a special artificial lens used in cataract surgery that can be adjusted after it's placed in the eye) holds up over time in people who already have it.
San Antonio, TexasAges Any age - NCT06600945Recruiting
Comparing two muscle relaxants for cataract surgery
This trial tests if adding magnesium sulfate to a standard muscle relaxant (atracurium) improves local anesthesia for cataract surgery. It may help patients stay comfortable during the procedure.
MinyaAges 20–80 - 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 - NCT05822089Recruiting
Comparing two cataract lens types in the same person
This study compares two different cataract (intraocular) lens options in each eye of the same person. It aims to see which lens gives better distance vision after standard cataract surgery.
ViennaAges 50–100 - NCT05797298Recruiting
Toric lens implant surgery for cataracts
This trial studies implanting a special “toric” lens to improve vision for people with cataracts. It may help reduce the need for glasses for some people, depending on their eye measurements.
Shanghai, ChinaAges Any age - NCT07006428Recruiting
Comparing two types of multifocal lens implants for cataract surgery
This trial compares the Clareon PanOptix lens with another similar multifocal lens to see which provides better vision after cataract surgery. It has two stages: one for people who already had the lenses implanted, and one for those who are planning to have cataract surgery.
Torrance, CaliforniaAges Any age - 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 - 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 - NCT07036510RecruitingPhase 1/Phase 2
Safety and effectiveness of a timolol eye implant for glaucoma patients having cataract surgery
This trial tests a sustained-release implant that delivers timolol, a medicine to lower eye pressure, for people with glaucoma or high eye pressure who are also having cataract surgery. The implant is placed during surgery and may provide long-term pressure control without daily eye drops.
