Comparing two types of trifocal lenses for cataract surgery
Part of Eyes & vision clinical trials.
This study compares two different trifocal toric intraocular lenses (special lenses that correct both near, far, and astigmatism) used during cataract surgery. Researchers want to see which lens gives better results for people with cataracts and astigmatism.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 21 years or older
- You have been diagnosed with a cataract
- You have regular astigmatism between 0.75 and 4.5 diopters (measured before surgery)
- You have not had any previous eye surgery (like for cataracts or cornea)
- You are not pregnant or breastfeeding (if you could become pregnant, you must use effective birth control during the study)

Other trials that look related to this one.
This study compares five different advanced lenses (that give a range of focus) with a standard single-focus lens for cataract surgery. It aims to see which lens provides the best overall vision.
This study compares three types of toric lenses (lenses that correct both cataracts and astigmatism) to see how well they stay in place after surgery. It may help you choose the best lens for your cataract surgery.
This study compares two types of artificial lenses placed during cataract surgery to see which one gives better vision for people with cataracts and astigmatism. You will receive the same type of lens in both eyes.
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 different artificial lens implants (called intraocular lenses or IOLs) to see which gives the best vision after cataract surgery. If you have cataracts in both eyes and need surgery, you may be able to join.
This study tests a special lens implant (toric lens) for people having cataract surgery who also have astigmatism. The lens corrects both the cataract and the astigmatism, potentially giving you clearer distance vision without glasses.
