Better light, better sight: new study on Post-Surgery vision
NCT ID NCT07077967
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how different types of artificial lighting affect how well people see after having presbyopia (age-related blurry near vision) corrected with special extended-depth-of-focus lens implants. Researchers will measure the minimum light needed for clear distance vision in 100 adults aged 45 to 75. The goal is to create better lighting guidelines for people with these lenses.
