- NCT06539637RecruitingEarly Phase 1
Ketorolac levels in eye fluid during cataract and vitrectomy surgery
This study looks at how much of the drug ketorolac (a pain and inflammation medicine) gets into the fluid inside your eye when it's given as eye drops during combined cataract and vitrectomy surgery. It may help doctors understand if using another drug called phenylephrine alongside it changes those levels.

StrasbourgAges 18 years+ - NCT06659419Recruiting
Cataract surgery registry using Centurion machines
This study collects information from people who had routine cataract surgery with a specific machine (Centurion). It helps doctors learn more about how these surgeries go and improve care.
ParisAges Any age - NCT06681688RecruitingPhase 1/Phase 2
Comparing two approaches to prevent cataract surgery complications
This study compares two ways to prevent complications after cataract surgery. One group gets a special combination of eye drops and a steroid injection before surgery, and the other group gets standard care. The goal is to see which approach leads to fewer problems after surgery.
Venice, FloridaAges 18 years+ - NCT06712758Recruiting
Cataract surgery with new technique for glaucoma patients
This trial tests a newer, gentler cataract surgery method in people who have both glaucoma and cataracts. It aims to lower eye pressure safely during the procedure.
GeelAges Any age - NCT06781970Recruiting
Vitamin C for eye cell protection during cataract surgery
This trial tests whether taking vitamin C before and after cataract surgery can help protect the inner layer of the eye. It is for people aged 60 or older with hard, age-related cataracts who are having phacoemulsification surgery.
Jakarta, DKI JakartaAges 60 years+ - NCT06826417Recruiting
Anxiety and satisfaction in cataract surgery patients
This study looks at how anxiety before cataract surgery affects your satisfaction after the operation. It also tests if a common anti-anxiety medicine (XANAX) can help anxious patients feel more comfortable during surgery.
Taipei, TaiwanAges 18–80 - NCT06886373RecruitingPhase 4
Systane drops before and after cataract surgery for dry eye
This study tests whether using Systane COMPLETE eyedrops before and after cataract surgery helps improve dry eye symptoms and eye comfort. It is for people who were in a previous related trial or are new cataract patients with dry eye.
TaipeiAges 20–85 - NCT06922084RecruitingPhase 4
Comparing three types of artificial lens implants for cataract surgery
This study tests different artificial lens implants (called intraocular lenses or IOLs) to see which gives the best vision after cataract surgery. If you have cataracts in both eyes and need surgery, you may be able to join.
Plymouth Meeting, PennsylvaniaAges 40 years+ - NCT06966167Recruiting
Laser vs. standard cataract surgery in Fuchs' dystrophy
This study compares two types of cataract surgery in people with Fuchs' dystrophy: one using a laser and the standard method. It looks at which approach gives better results for the cornea and vision.
Shanghai, Shanghai MunicipalityAges 40 years+ - NCT06979752Recruiting
Testing a new cannula for glaucoma-cataract surgery
This trial tests whether a special cannula can help protect the eye during combined surgery for pseudoexfoliative glaucoma (a type of glaucoma with flaky deposits) and cataracts. It may offer better results than standard irrigation.
AvranchesAges 18 years+ - NCT06990074Recruiting
Study of the Polaris System for cataract surgery
This trial tests a new system called Polaris for removing cataracts and implanting a lens. It is for people with age-related cataracts who are healthy enough for routine cataract surgery.
San Salvador, San Salvador DepartmentAges 40–75 - NCT06997874RecruitingPhase 3
Surgery Comparison for Retinal Detachment Without Prior Cataract Surgery
This trial compares two types of surgery for people with a retinal detachment who still have their natural lens (no prior cataract surgery). One group gets vitrectomy alone; the other gets vitrectomy plus the lens removed at the same time. The goal is to see which approach leads to better outcomes.
AylesburyAges 50 years+ - NCT07030946Recruiting
Video education to reduce anxiety before cataract surgery
This study tests whether watching educational videos before cataract surgery can help reduce anxiety and improve how well patients understand their care. It is for people having their first cataract surgery who are comfortable using digital devices.
Keelung, KeelungAges 18 years+ - NCT07036367RecruitingPhase 4
Melatonin before cataract surgery for older adults
This trial is testing whether a melatonin tablet placed under the tongue before surgery can help older adults feel calmer and more comfortable during cataract surgery. Melatonin is a natural sleep hormone that may reduce anxiety without the side effects of common sedatives.
Cairo, EgyptAges 60 years+ - NCT07052825Recruiting
Testing a ring for lens stability in nearsighted cataract patients
This study tests whether a small ring placed around the lens implant during cataract surgery helps keep the implant stable for people with high myopia (severe nearsightedness). It could lead to better vision and fewer complications after surgery.
Shanghai, Shanghai MunicipalityAges 18–90 - NCT07074431Recruiting
Comparing two methods for cataract surgery
This trial compares a new high-frequency pulsed vacuum technology to standard cataract surgery (phacoemulsification) for treating cataracts in both eyes. It aims to see which method works better and is safer for people with mild to moderate cataracts.
AmiensAges 18 years+ - NCT07080229RecruitingPhase 3
Nasal spray for blood pressure during cataract surgery in older adults
