CATARACT

This study will develop an artificial intelligence (AI) system to detect common eye diseases like glaucoma, cataracts, and diabetic retinopathy. Researchers will use 15,000 existing eye images from two clinics in Costa Rica, without recruiting new participants. The goal is to cre…

This study tests whether a single anti-VEGF injection given during cataract surgery works as well as three injections (one during surgery and two afterward) to prevent diabetic retinopathy from getting worse. About 166 diabetic adults with non-advanced eye disease will take part.…

This study will compare three different tear substitute eye drops to see which one works best for reducing discomfort after cataract surgery. 300 adults with cataracts will be observed after their surgery. The goal is to find which eye drop provides the most relief from dry eye s…

This study compares two enhanced monofocal intraocular lenses (IOLs) used in cataract surgery to see which provides better vision at intermediate distances, like arm's length. About 30 adults with age-related cataracts will receive one of the two lenses. The goal is to improve vi…

This study tests whether a special lens setting during cataract surgery can improve vision for people with high myopia (severe nearsightedness). 66 adults will get an enhanced lens in both eyes, with one eye set for distance and the other for near vision. Researchers will compare…

This study compares a new trifocal artificial lens to an already approved lens for people having cataract surgery. The goal is to see if the new lens gives better vision at near, middle, and far distances without glasses. About 66 adults with cataracts and low astigmatism will ta…

This study tests a special lens used during cataract surgery to help people see better afterward. About 130 adults with age-related cataracts will get the lens, and doctors will check how accurate their vision becomes. The goal is to make sure the lens is safe and works well.

This study tests a new type of lens (PureSee) placed during combined cataract and cornea transplant surgery. The goal is to see if it helps people see better at arm's length and reduces the need for glasses. Ten adults with both cataracts and Fuchs corneal dystrophy will be follo…

This study tests whether a special lens implant (extended depth of focus) can give better vision and less need for glasses than a standard lens in people with both glaucoma and cataracts. About 74 adults with mild to moderate open-angle glaucoma will receive one lens type in each…

This study compares two eye drop treatments—rebamipide and diquafosol—for managing dry eye disease in people having cataract surgery. About 60 adults with mild to moderate dry eye will use one of the drops for one month before and three months after surgery. The goal is to see if…

This study compares two ways to perform cataract surgery: one that breaks up the lens inside the lens capsule and one that does it above the capsule. The goal is to see which method helps patients see clearly sooner after surgery. About 128 adults aged 50 to 90 with dense catarac…

This study looks at whether giving sedation (medication to help you relax) during cataract surgery improves patient comfort and satisfaction. About 120 adults having routine cataract surgery will be randomly assigned to receive either no sedation, a mild sedative, or a sedative p…

This study will analyze eye images and brain scans from over 200,000 people to find connections between eye features and diseases like stroke or diabetes. Researchers aim to create models that predict brain and body conditions from simple eye exams. The goal is to enable earlier …

This study will check the eyes of 3,000 people in Xinxing County to see how common vision problems like needing glasses or cataracts are, and how well they are being treated. Participants include school children, seniors over 65, and people with diabetes. The goal is to measure a…

This study aims to improve how doctors calculate the correct lens power for cataract surgery. Researchers will use artificial intelligence and different eye imaging techniques to measure lens diameter and predict the best lens position. The goal is to help patients see better aft…

This study looks at whether asking people with cataracts to write down their personal reasons for wanting surgery helps them decide to go through with it. About 268 adults who are eligible for cataract surgery will be split into two groups: one group will do a short writing exerc…

This study will test a new device for eye surgery that removes cataracts and repairs the inside of the eye. About 205 adults will take part to see if the device is safe and works as well as similar tools already in use. The main goal is to check for problems during surgery and ma…

This study looks at why many people in rural Assam who are referred for eye care do not go to the hospital for treatment. Researchers will test a program that includes patient navigation, transport help, and reminders to improve the number of people who complete their hospital vi…

This study looks at whether using a vascular imaging device (a special camera that helps see veins) makes it faster and easier to place an IV in children under 18. About 500 kids having day surgery or procedures outside the operating room will take part. Researchers will compare …
