Comparing standard lens implants for very nearsighted cataract patients
Part of Eyes & vision clinical trials.
This trial tests two types of artificial lenses (IOLs) in people with high nearsightedness and cataracts. It looks at which lens works better for vision recovery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 40 and 70 years old.
- Your eye is very long (more than 26 mm) due to high nearsightedness.
- You are able to understand instructions and return for all follow-up visits.
- You do not have moderate or severe dry eye.
- You do not have age-related macular degeneration from high nearsightedness.
- You have not had any eye surgery before and have no other eye diseases or complications.

Other trials that look related to this one.
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.
This study compares two types of multifocal intraocular lenses (IOLs) used during cataract surgery to improve vision at multiple distances. It is for people with cataracts in both eyes who have not had previous eye surgery.
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 advanced intraocular lenses (IOLs), the Tecnis PureSee and the Comfort Z-EDOF, placed during cataract surgery. The goal is to see which lens gives better all-around vision, with the dominant eye corrected for distance and the non-dominant eye slightly under-corrected to help with reading.
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 trial tests new enhanced monofocal intraocular lenses (special lens implants) to see if they improve vision after cataract surgery. It is for people with age-related cataracts in both eyes who are otherwise healthy.
