Laser eye surgery outcomes for age-related close-up vision
Part of Eyes & vision clinical trials.
This study is testing how well a specific laser eye surgery called PRESBYOND improves vision in people with presbyopia (age-related difficulty seeing close up). It helps see if the procedure is effective and safe for patients aged 45 to 65.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 45 and 65 years old.
- You are scheduled for LASIK surgery on both eyes using the PRESBYOND laser treatment.
- Before surgery, your vision with glasses or contacts must be at least 20/20 in each eye.
- You need to stop wearing contact lenses: for at least 1 month if you wear hard contacts and 1 week if you wear soft contacts before the pre-surgery checkup.
- Your cornea (the clear front part of your eye) must be healthy and thick enough (at least 250 microns remaining after surgery).
- You must not have certain eye conditions (like mixed astigmatism, irregular astigmatism, or significant dry eye) or have had prior eye surgery (like LASIK, PRK, or SMILE).

This trial tests a new treatment called the VIS Opti-K™ System to help people with presbyopia (age-related trouble seeing up close) see better without glasses. It uses a special lens to improve near vision in one eye while keeping distance vision clear.
This study compares two laser eye surgery approaches for people over 40 who need reading glasses. Both methods use LASIK to reduce or eliminate your need for glasses, but they work differently—one eye may be set for distance and one for close-up (monovision), or both eyes may be adjusted for mixed vision (blended vision).
This study tests a new light-based treatment for presbyopia (age-related trouble focusing on close objects) and near vision correction. It may help reduce the need for reading glasses by reshaping the cornea, the clear front part of the eye.
This trial tests a new laser device (called TENEO 317 Model 2) for correcting nearsightedness (myopia) with or without astigmatism. The treatment is a type of laser eye surgery that reshapes the cornea so you can see clearly without glasses or contacts.
This study tests a new laser (called TENEO 317 Model 2) for vision correction. If you're already scheduled for LASIK to fix nearsightedness or farsightedness (with or without astigmatism), you may be eligible. The study checks if this new laser is safe and works well.
This study looks at how different types of LASIK affect the quality of vision for people with mild to moderate nearsightedness. It aims to help patients understand which procedure might give them the best visual outcomes.
