Recruiting studies
- NCT05980117RecruitingPhase 4
Remimazolam sedation for cataract surgery

A study of a new lens for people who had laser eye surgery
This study looks at how well a type of artificial lens (Clareon Vivity) works for people who have had laser eye surgery in the past and now need cataract surgery. It aims to see if this lens gives good vision without glasses.
Ogden, UtahAges Any age - NCT07178639Recruiting
Comparing three eye drops after cataract surgery
This trial tests three different anti-inflammatory eye drops to see which works best for pain and swelling after cataract surgery. You may join if you are scheduled for cataract surgery only, and you can apply the drops yourself or have help.
KolínAges 18 years+ - NCT07135570Recruiting
My Eyes, My Light: Amar Chokh, Amar Alo
This trial is studying people living in Char Fasson, Bangladesh, to see who might have undiagnosed eye problems. It's a local screening program to catch eye issues early.
Char Fasson, BholaAges 35 years+ - NCT07126470Recruiting
Ring for better lens placement in RP cataract surgery
This trial tests whether using a capsular tension ring (a small support ring) during cataract surgery helps keep the artificial lens more stable in people with retinitis pigmentosa (RP) and cataracts. It may reduce lens shifting after surgery.
Guangzhou, GuangdongAges 18 years+ - NCT07084545Recruiting
Cataract surgery lens for people with prior laser vision correction
This trial tests a special lens (CT LUCIA) for people who had laser vision correction in the past and now need cataract surgery. It aims to see how well the lens works in these patients.
Sugar Land, TexasAges 18 years+ - NCT07080229RecruitingPhase 3
Nasal spray for blood pressure during cataract surgery in older adults
This trial tests whether a nasal spray of dexmedetomidine can help control blood pressure in older adults with high blood pressure who are having cataract surgery. It may keep your blood pressure more stable during the procedure.
Ismailia, Ismailia GovernorateAges 65 years+ - 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+ - 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 - 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+ - 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+ - 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 - 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+ - 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+ - 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+ - 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 - NCT06874452RecruitingPhase 4
Anti-anxiety pill for second cataract surgery
This study tests if giving the anti-anxiety pill alprazolam (XANAX) before your second cataract surgery helps reduce anxiety and improve satisfaction with the procedure.
TaipeiAges 18–80 - 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 - NCT06824935Enrolling by invitation
Cataract surgery anesthesia needs study
This study looks at how much anesthesia is needed during outpatient cataract surgery. It may help find the right approach for your comfort and safety.
IstanbulAges 18 years+ - NCT06616506Recruiting
AI for cataracts in high myopia
This trial uses artificial intelligence to study cataracts in people with high myopia (very nearsighted). It aims to improve diagnosis and treatment planning for cataract surgery.
Shanghai, Shanghai MunicipalityAges Any age - NCT06429527Enrolling by invitation
Smartphone app for follow-up after cataract surgery
This trial tests whether checking your vision at home with a smartphone app (WHOeyes) and answering a few questions can safely replace a one-week in-person visit after cataract surgery. If you qualify, you'll help doctors see if app-based follow-up is convenient and reliable.
Guangzhou, GuangdongAges 50–80 - NCT05955846Recruiting
Testing a new cataract lens with a virtual aperture
This trial tests a specific cataract replacement lens to see how safe it is and how well it improves vision. If you have cataracts in both eyes and are good candidate for cataract surgery, this lens may help you see more clearly after surgery.
