Eye scan measurements in people with nearsightedness or farsightedness
Part of Eyes & vision clinical trials.
This study uses a simple, painless eye scan (called OCT) to measure the layers at the back of your eyes in people with nearsightedness or farsightedness. The results help doctors better understand normal variations in these measurements for people with different prescriptions.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older
- You need to have either nearsightedness (at least -0.50) or farsightedness (at least +0.50) based on your glasses or contact lens prescription
- Your eyes must be clear enough for a detailed scan (no clouding or other issues that block the scan)
- You cannot have had any prior eye surgeries
- You must not have glaucoma, optic nerve problems, or retinal diseases
- You must not have diabetes or high blood pressure that affects your eyes
- Your eye pressure (measured during the exam) must be below 21

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 looks at how well people with nearsightedness see and what factors affect their visual quality. It may help doctors understand how to improve vision care for people with myopia.
This study tests a new eye scanner that takes detailed pictures of the back of the eye. It may help doctors see eye problems more clearly and could lead to better care.
This study uses a special eye scanner (OCTA) to look at the choroid, a layer of blood vessels behind the retina, in people with high myopia. It will help doctors understand how high myopia affects this part of the eye and may guide future care.
This study uses a special eye scanner to measure the thickness of the clear front layer of the eye (cornea) in people with nearsightedness or farsightedness. The goal is to understand how refractive errors affect corneal thickness, which may help with future treatment planning.
This trial tests whether a special eye scan (OCT) can help guide eye surgery during the operation. It may improve how surgeons see and target the exact eye structures they need to treat.
