Study summary

The primary purpose of this study is to compare the Clareon/Clareon Toric Intraocular Lenses (IOLs) to the Eyhance/Eyhance Toric IOLs in binocular Best Corrected Distance Visual Acuity (BCDVA) at 3 months postoperative.

Read the detailed description

This study will enroll adults 22 years of age and older diagnosed with cataracts in both eyes with planned bilateral cataract removal by routine small incision phacoemulsification surgery. Subjects will attend up to 7 scheduled visits: A screening visit, two operative visits, and four post-operative visits. The expected individual duration of participation in the study is 3 months.

Eligibility criteria

Key Inclusion Criteria:

  • Planned bilateral cataract removal by routine small incision phacoemulsification surgery;
  • Planned implantation of either test or comparator IOL (per randomization) in at least one eye with approximately 1.00 - 3.00 diopter (D) of preoperative corneal astigmatism;
  • Predicted postoperative astigmatism of ≤ 0.5 D in both operative eyes based on a Toric calculator;
  • Other protocol-specified inclusion criteria may apply.

Key Exclusion Criteria:

  • Any disease or pathology, other than cataract, that (in the investigator's opinion) may reduce potential Best Corrected Distance Visual Acuity (BCDVA) to a level worse than 0.2 logarithm minimum angle of resolution (logMAR);
  • (in the investigator's opinion) corneal pathology, dry-eye or ocular surface disease that would adversely affect a) the biometry measures and/or toric calculations and b) the visual outcome;
  • History of previous intraocular or corneal surgery (including laser-assisted in situ keratomileusis (LASIK));
  • Any other planned ocular surgical procedures including but not limited to limbal relaxing incision (LRI), astigmatic keratotomy, LASIK, and retinal laser treatment within the study time frame;
  • Other protocol-specified exclusion criteria may apply.

Interventions

  • DeviceClareon IOL

    Alcon Clareon Aspheric Hydrophobic Acrylic IOL for the visual correction of aphakia in adult patients in whom a cataractous lens has been removed.

What researchers measure

Primary outcomes

  1. Mean Binocular Best-corrected Distance Visual Acuity (BCDVA) at 4 Meters Under Bright Lighting Conditions

    Visual acuity was tested at a distance of 4 meters using a refraction chart and the correction obtained from a manifest refraction. BCDVA was measured in logarithm minimum angle of resolution (logMAR) units, with 0.00 logMar equating to 20/20 Snellen, which is considered normal distance eyesight. A lower logMAR value (more negative value) indicates better eyesight. This was a subject based assessment, and subject assigned a single score for both eyes.

    Time frame: Month 3 postoperative visit

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2022 to primary completion in Oct 2023, 12 months.

Results were first posted in Oct 2024, 1 year after primary completion.

Of 190 industry-sponsored interventional studies with no phase under Cataract, half reached primary completion within 16 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 28. This study's 12 months is below that.

Counting every sponsor, half of 490 studies reached it within 17 months; a quarter within 9 and three quarters within 28.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 30, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
