Presbyopia-correcting lens implants for complex cataracts
Part of Eyes & vision clinical trials.
This study tests special lenses (IOLs) that aim to correct presbyopia (trouble seeing up close) in people with complex cataracts or other eye conditions. It may help if you have a lens that is partially out of place, long-term eye inflammation, a cataract after laser eye surgery, or if you are missing a lens and need a new one.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have one of these eye conditions: a lens that is partially out of place, long-standing quiet inflammation with a cataract, a cataract after previous laser eye surgery for nearsightedness, or no lens in your eye with weak support for a new lens.
- You have not had prior eye surgeries like glaucoma surgery, vitrectomy, or corneal laser surgery (except for the specific laser surgery group).
- You do not have serious eye diseases such as glaucoma, diabetic retinopathy, macular degeneration, or severe corneal scarring.
- Your eye measurements meet certain standards (like pupil size, corneal shape, and expected post-surgery vision) that your doctor will check.
- You are willing to commit to follow-up visits and want to improve your vision at all distances.

Other trials that look related to this one.
This study tests a new type of artificial lens (called an accommodating IOL) that may help your eye focus on objects at different distances after cataract surgery. The lens is implanted during your standard cataract operation.
This study tests a new type of trifocal lens implant to see how well it improves vision at all distances after cataract or lens replacement surgery. It may help you become less dependent on glasses.
This study tests two types of implantable lenses that correct astigmatism (blurry vision from an irregularly shaped cornea). You keep your own natural lens, and the new lens is placed in front of it—no laser or lens removal needed. The goal is to see which lens works better and is safer.
This trial tests a new intraocular lens (IOL), which is an artificial lens placed inside the eye after cataract removal, to see if it is safe and effective for improving vision. It might offer a good option for people who need cataract surgery.
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.
This study tests a new type of artificial lens (intraocular lens, or IOL) that is put in your eye during cataract surgery. The lens is designed to help you see well at all distances, potentially reducing your need for glasses after surgery.
