New laser technique aims to sharpen both near and far vision in one go
NCT ID NCT07512089
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This study tests if a newer laser method (PRESBYOND laser blended vision) is better than standard monovision LASIK for treating presbyopia, which makes it hard to see up close as you age. About 100 adults aged 40 to 55 will be randomly assigned to one of the two surgeries. They will have their vision checked over 6 months to see which method gives clearer sight at all distances.
