Comparing different intraocular lenses for cataract surgery
Official title: A Prospective, Randomized, Subject and Vision-assessor Masked, Multicenter Study Comparing Bilateral Clareon PanOptix, Bilateral Clareon PanOptix Pro, and Mixed Clareon PanOptix Pro/Vivity Intraocular Lens Implantation in Cataract Subjects
Run by Berkeley Eye Center · NCT06922084 · Data updated 2026-11-12
This study is testing three different types of lenses used in cataract surgery to see which one helps people see better after the procedure.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 40 and older who are scheduled for cataract surgery in both eyes and meet specific visual acuity and astigmatism criteria.
✕Probably not a fit
Patients with significant ocular conditions or those who are pregnant or breastfeeding may not benefit from this study.

What this trial studies
This study is a prospective, randomized, multicenter trial that evaluates the effectiveness of three types of intraocular lenses: Clareon PanOptix, Clareon PanOptix Pro, and a mix of Clareon PanOptix Pro/Vivity in patients undergoing cataract surgery. The study is designed in two stages, with the first stage involving initial enrollment across three arms, followed by a head-to-head comparison based on the data collected. Participants will be masked to the treatment they receive, and the study aims to assess visual outcomes post-surgery.
Why it matters
Potential benefit: If successful, this study could provide insights into the best intraocular lens options for improved visual outcomes in cataract patients.
How similar studies have gone: Other studies have explored various intraocular lenses, but this specific comparison of these three types is novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Adult cataract patients aged 40 years and older scheduled for age related cataract surgery in both eyes. * Ability to understand and sign an ethics committee-approved informed consent form. * Willingness and ability to attend all scheduled study visits as required by the protocol. * Postoperative potential visual acuity of 20/25 or better in each eye, as determined by the investigator. * Preoperative corneal astigmatism that can be corrected with a T3 or T4 toric IOL, or with a spherical IOL and LRIs or AKs resulting in a predicted postoperative astigmatism of less than 0.5 diopters (D). * Ability to understand and complete questionnaires. Exclusion Criteria: * Women who are pregnant, planning to become pregnant during the study, or breastfeeding. * Ocular conditions that could confound study results, including moderate to severe corneal pathology, irregular astigmatism, moderate to severe dry eye, preexisting retinal diseases such as macular degeneration or diabetic retinopathy. * Any form of confirmed glaucomatous damage (ie, mild, moderate, or severe glaucoma). * Participation in another clinical study that could interfere with the results. * Systemic conditions that may affect healing or visual outcomes (e.g., uncontrolled diabetes mellitus, certain autoimmune disorders). * Subjects with nystagmus, strabismus, zonular laxity or dehiscence, and pseudoexfoliation. * Prior ocular surgery (except for uncomplicated cataract surgery in the fellow eye). * Participants desiring monovision. * Any active ocular infection or inflammation (except for routine post-operative inflammation in the fellow eye) * Psychiatric or cognitive disorders that may impair the ability to comply with study procedures or provide accurate self-assessments. * RMS total higher-order aberrations (HOAs) \>0.70 µm or coma \>0.40 µm as measured by tomography or topography with a 4 mm pupil setting.
