Testing a new cataract lens with a virtual aperture
Part of Eyes & vision clinical trials.
This trial tests a specific cataract replacement lens to see how safe it is and how well it improves vision. If you have cataracts in both eyes and are good candidate for cataract surgery, this lens may help you see more clearly after surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re between 40 and 75 years old and need cataract surgery in both eyes.
- Your current vision with glasses is worse than 20/30, and your surgeon thinks you can reach 20/25 or better after surgery in each eye.
- Your eye surface (cornea) must be fairly regular, with low astigmatism (less than 0.75).
- Your eye measurements (including lens power) must fall within the study’s available lens power range (+16 to +24).
- You must not have had prior corneal or inside-eye surgery, and you must not have certain cornea/eye inflammation or structural problems.
- You can’t want monovision, and you generally can’t have dry-eye treatments (other than artificial tears) or medications that affect vision or pupil size.

This study tests a new type of lens implant that may give you a wider range of clear vision after cataract surgery, potentially reducing your need for glasses. If you have cataracts in both eyes and meet the eye health criteria, this trial could help improve your vision with one surgery.
This study tests two types of intraocular lenses (IOLs) used in cataract surgery to see which one gives better visual function after the operation. It may help you see better at different distances without glasses.
This trial is a registry for people having cataract surgery in both eyes. It collects information on different types of artificial lenses used to improve vision, and follows up to see how well they work.
This study tests a new type of lens implant that gives you a wider range of clear vision after cataract surgery. It uses a special laser to help remove the cataract, and the lens may help you see better at near, far, and in between without glasses.
This study tests whether a small ring placed around the lens implant during cataract surgery helps keep the implant stable for people with high myopia (severe nearsightedness). It could lead to better vision and fewer complications after surgery.
This study compares two types of extended depth of focus (EDOF) lens implants to see how well they improve vision after cataract surgery. It may help people who need both distance and near vision without glasses.
