Brief Summary
Title: Visual Outcomes in Patients Contralaterally Implanted with PanOptix Pro and Clareon Vivity Compared to Bilateral Implantation of PanOptix Pro Sponsor: Brian Shafer, MD, Shafer Vision Institute Objective: To compare visual outcomes and patient-reported satisfaction in cataract patients receiving either: Contralateral implantation (PanOptix Pro in one eye, Clareon Vivity in the other) Bilateral PanOptix Pro implants Key hypotheses: Contralateral implantation is non-inferior for binocular best-corrected distance visual acuity (BCDVA) at 4 m. Contralateral implantation yields superior visual disturbance outcomes (less halo, glare, starburst). Design: Prospective, randomized, double-masked, two-arm, multicenter study N = 346 subjects (173 per arm) 5 surgeons across 4 sites All patients undergo bilateral phacoemulsification aiming for emmetropia Randomized 1:1 to: Arm 1: PanOptix Pro (dominant eye) + Clareon Vivity (non-dominant eye) Arm 2: Bilateral PanOptix Pro Surgical Details: Femtosecond laser optional Second eye surgery ≤4 weeks after first Toric IOLs or arcuate incisions for residual astigmatism ≤0.50 D Biometry with ARGOS, IOLMaster 700, or Lenstar Toric alignment with ORA, Callisto, etc. Assessments: Visual acuity at 4 m, 66 cm, 40 cm, 33 cm in photopic and mesopic conditions Defocus curves, contrast sensitivity (with/without glare) Manifest refraction Patient-reported outcomes via IOLSAT and QUVID questionnaires Masking: subjects and assessors unaware of IOL assignments Endpoints (at 3 months): Primary: Binocular BCDVA (4 m) Secondary: DCIVA, DCNVA, UDVA, UIVA, UNVA, defocus curves, refractive outcomes, visual disturbance scores Exploratory: Mesopic VA, low contrast VA, contrast sensitivity, satisfaction scores Eligibility Criteria: Adults with bilateral age-related cataracts Plan for bilateral phacoemulsification Expected postop monocular BCDVA ≤0.1 logMAR (20/25) Residual astigmatism ≤0.50 D Exclusions include corneal pathology, macular disease, glaucoma, prior ocular surgery, amblyopia, severe dry eye, high HOA (\>0.6 um), monovision preference, active infection/inflammation, pregnancy Statistics: Non-inferiority margin: 0.1 logMAR Superiority testing for visual disturbances Step-down testing hierarchy for primary and secondary outcomes Sample size powered for 80% at α=0.05, accounting for 10% dropout Two-proportion Z-tests for dysphotopsia rates Safety Monitoring: Adverse Events (AEs) and Serious Adverse Events (SAEs) captured Definitions, severity grading, and reporting procedures specified Protocol deviations documented and reported per IRB requirements Data Handling: Data anonymized via subject numbers Stored securely (locked cabinets, password-protected systems) Study registered at ClinicalTrials.gov Visit Schedule: Screening: Consent, eligibility, history 1st \& 2nd Eye Surgery Visits 3-Month Post-Op Visit: Comprehensive visual assessments, questionnaires, AE review

Outcome Measures
Primary Outcomes (1)
Binocular Best-Corrected Distance Visual Acuity (BCDVA) at 4 meters
Binocular BCDVA measured in logMAR under photopic conditions (85 cd/m²) at 4 m using standardized ETDRS charts with the M\&S Clinical Trial Suite (CTS). Non-inferiority margin of 0.1 logMAR between treatment arms.
3 months post-operative visit
Study Arms (2)
Contralateral PanOptix Pro and Clareon Vivity
EXPERIMENTALSubjects randomized to this arm will receive bilateral cataract surgery with contralateral implantation: Alcon Clareon PanOptix Pro or PanOptix Pro Toric IOL in one eye and Alcon Clareon Vivity or Vivity Toric IOL in the fellow eye. The Vivity IOL will be implanted in the dominant eye, with all surgeries targeting emmetropia. Residual astigmatism will be managed to ≤0.50 diopters using toric IOLs or arcuate incisions as needed.
Bilateral PanOptix Pro
ACTIVE COMPARATORSubjects randomized to this arm will receive bilateral cataract surgery with implantation of Alcon Clareon PanOptix Pro or PanOptix Pro Toric IOLs in both eyes. All eyes will be targeted for emmetropia, and residual astigmatism will be controlled to ≤0.50 diopters using toric IOLs or arcuate incisions as appropriate.
Interventions
Bilateral cataract surgery with contralateral implantation: Alcon Clareon PanOptix Pro (or PanOptix Pro Toric) intraocular lens in one eye and Alcon Clareon Vivity (or Vivity Toric) intraocular lens i
Bilateral cataract surgery with implantation of Alcon Clareon PanOptix Pro (or PanOptix Pro Toric) intraocular lenses in both eyes. All surgeries target emmetropia with residual astigmatism ≤0.50 diopters using toric IOLs or arcuate incisions as needed.
Eligibility Criteria
You may qualify if:
- Bilateral diagnosis of age-related cataracts.
- Planned bilateral cataract removal by phacoemulsification with either:
- Contralateral implantation of Clareon PanOptix Pro/PanOptix Pro Toric in one eye and Clareon Vivity/Vivity Toric in the fellow eye, or
- Bilateral implantation of Clareon PanOptix Pro/PanOptix Pro Toric.
- Expected best monocular corrected distance visual acuity (BCDVA) of 0.1 logMAR (Snellen 20/25) or better in both eyes postoperatively, as determined by the surgeon.
- Residual astigmatism expected to be ≤0.50 diopters in both eyes postoperatively (using toric IOLs or arcuate incisions as needed).
- Normal ocular findings aside from cataracts.
You may not qualify if:
- Preexisting macular disease or other retinal degenerative disease expected to cause vision loss.
- Glaucoma.
- Severe dry eye disease.
- Nystagmus or strabismus.
- Zonular laxity or dehiscence, pseudoexfoliation.
- Any condition (in the investigator's opinion) that may affect study endpoints.
- Previous history of any ocular surgery, including corneal refractive surgery.
- Subjects desiring monovision.
- History of amblyopia or monofixation syndrome with poor stereoscopic vision.
- Total corneal higher-order aberrations (HOA) greater than 0.6 microns.
- Any planned simultaneous or combined procedures at the time of cataract surgery (e.g., MIGS).
- Participation in another clinical study that could interfere with study results.
- Any active ocular infection or inflammation.
- Pregnant, breastfeeding, or planning to become pregnant during the study (as determined by verbal inquiry).
