Chandigarh, Punjab HaryanaAges Any age - NCT07460557Recruiting
Link between jaw shape and vision
This study looks at how the shape of your jaw and face might relate to your eyesight. Healthy young adults aged 21 to 25 are needed to see if there is a connection.
ZagrebAges 21–25 - NCT05856786Recruiting
Study how eye focusing surgery changes OCT measurements
This study looks at how refractive (vision-focusing) surgery affects OCT test images inside the eye. It may help doctors measure and track eye changes more accurately after surgery.
Omaha, NebraskaAges 19 years+ - NCT07176429Enrolling by invitation
Comparing two light adjustable lenses after cataract surgery
This study compares how well two types of light adjustable lenses (LAL and LAL Plus) help you see at different distances after cataract surgery, compared to a standard lens. It aims to see if the light adjustable lens can reduce the need for glasses.
Valencia, CaliforniaAges 18 years+ - NCT07746804Recruiting
School program to prevent nearsightedness in children
This study tests a school-based program to help prevent nearsightedness (myopia) in children who are not yet nearsighted but have a higher risk of developing it. It uses a simple, non-invasive method called auricular acupressure, which involves placing small seeds on the ear, to see if it can keep eyes healthy and reduce the chance of needing glasses.
Shanghai, Shanghai MunicipalityAges 6–11 - NCT07746752Recruiting
School program to prevent nearsightedness in kids with good eye reserve
This study tests whether a school-based program can help prevent nearsightedness (myopia) in children who currently have good distance vision and enough 'eye reserve' (hyperopic reserve) to potentially avoid becoming nearsighted. It focuses on early elementary students to see if simple activities can keep their eyes healthy.
Shanghai, Shanghai MunicipalityAges 6–11 - NCT07746778Recruiting
School program to slow nearsightedness in children
This study tests whether a school-based program can help slow the progression of nearsightedness (myopia) in children who are either already nearsighted or at risk of becoming nearsighted. It may help reduce the need for stronger glasses in the future.
Shanghai, Shanghai MunicipalityAges 6–11 - NCT07490444RecruitingPhase 2
Better glasses for children with Down syndrome
This trial tests a new way to make eyeglass prescriptions for children with Down syndrome, ages 5 to 12. The goal is to see if it improves their vision.
Columbus, OhioAges 5–12 - NCT03030755Recruiting
Imaging test and personalized modeling for keratoconus
This trial uses special eye imaging to measure how your cornea (the eye’s clear front surface) changes, and then builds a personalized model for you. It may help doctors plan safer, more tailored treatment for keratoconus—especially if you’re considering LASIK.
Cleveland, OhioAges 16–80 - NCT03455478Recruiting
Study of adult vision health in Shanghai residents
