Eye nerve measurements in nearsighted and farsighted adults
Part of Eyes & vision clinical trials.
This study uses an OCT (a special camera that scans the back of your eye) to measure the thickness of nerve layers in people with nearsightedness (myopia) or farsightedness (hyperopia). It helps doctors understand how different prescriptions affect eye structures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have myopia (nearsightedness, -0.50 or worse) or hyperopia (farsightedness, +0.50 or better)
- You have not had any eye surgery before
- Your eyes are healthy – no glaucoma, retinal disease, or other eye conditions
- You do not have diabetes or high blood pressure that affects your eyes
- You have low astigmatism (less than ±2.00 diopters)

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.
This study examines why some people with nearsightedness see better than others, even with similar eyeglass prescriptions. Researchers will ask you questions and perform eye exams to understand the factors that influence your visual comfort and clarity.
This study uses advanced eye imaging to understand how nearsightedness (myopia) develops in children. It may help researchers find better ways to manage or slow myopia progression.
This study checks eye measurements (like “axial length,” the distance inside the eye) in adults with new-onset nearsightedness who are not using any myopia-control treatment yet. The results may help guide how myopia-control strategies are best applied.
This study uses OCTA, a type of eye scan, to look at the blood vessels in the back of the eye in people who are very nearsighted (high myopia). It aims to understand how high myopia affects the retina's blood supply, which could help with future eye care.
This study uses a special eye imaging technique to map the thickness of the clear front layer of your eye (cornea) in people with nearsightedness or farsightedness. The goal is to better understand how corneal thickness relates to refractive errors and help improve eye care.
