Comparing two eye scanners for measuring vision quality
Part of Eyes & vision clinical trials.
This study compares two different eye-mapping technologies to see which one better measures tiny optical imperfections (called higher-order aberrations) in the cornea. This could help doctors choose the most accurate tool for planning vision correction procedures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a refractive error between +6 and -8 diopters with astigmatism up to -6 diopters.
- You do not have diabetes or other systemic diseases that could affect your eyes.
- You do not have keratoconus or suspected keratoconus, and you are not amblyopic (lazy eye).
- Your best corrected vision (with glasses or contacts) is at least 20/25.
- You have no glaucoma, and you have not had prior eye surgery or trauma.

This study uses a special eye scanner to compare the front part of the eye in people with keratoconus, people with high myopia and astigmatism, and people with normal corneas. It aims to better understand the differences, which may help improve diagnosis and treatment.
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 study tests whether a special eye scan called OCT can better identify causes of irregular cornea shape. Results may help doctors sort out different cornea problems so treatment choices, like certain procedures, can be more targeted.
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 trial tests two different devices that measure your eyes before cataract surgery to see which one helps doctors choose the best lens implant. The goal is to get your vision as close to perfect as possible after surgery.
This study compares two eye measurement devices to see if they give similar results in people with healthy eyes, keratoconus (a cone-shaped cornea), daily contact lens use, dry eye, or after laser eye surgery. Participating may help ensure these devices are accurate for different patients.
