Visual Performance Differences Between Clareon PanOptix and a Comparable Multifocal Intraocular Lens
This is a two-part, multi-center, investigator-initiated clinical study comparing visual outcomes and patient satisfaction in subjects receiving bilateral implantation of either the Clareon PanOptix intraocular lens (IOL) or a comparable multifocal IOL. The study includes a retrospective/prospective pilot phase and a prospective, randomized comparison phase.
⁃ Stage 1: IIT Pilot
• Willing and able to understand and sign informed consent.
• Adult patients previously diagnosed with age-related cataracts bilaterally.
• Previous bilateral age-related cataract removal and with bilateral implantation of the Clareon PanOptix/ Clareon PanOptix Toric (T3-T4) or Comparable Multifocal Intraocular Lens (equivalent to T3-T4) closest to 2.5-5-months after implantation and \>2 weeks post YAG (if done) that were targeted for emmetropia.
• Best monocular corrected distance visual acuity was expected to be 0.1 logMAR (Snellen 20/25) or better in both eyes pre-operatively as determined by surgeon.
• Normal ocular findings aside from cataract.
⁃ Stage 2: Comparison
• Willing and able to understand and sign informed consent.
• Adult patient diagnosed with age-related cataracts bilaterally.
• Planned bilateral cataract removal by femtosecond laser-assisted phacoemulsification with bilateral implantation of the Clareon PanOptix/Clareon PanOptix Toric (T3-T4) or Comparable Multifocal Intraocular Lens (equivalent to T3-T4).
• Best monocular corrected distance visual acuity expected to be 0.1 logMAR (Snellen 20/25) or better in both eyes postoperatively as determined by surgeon.
• Residual astigmatism expected to be ≤ 0.50 diopters in both eyes postoperatively as determined by surgeon (after using either toric IOL or arcuate incision with laser).
• Normal ocular findings aside from cataract.
