Официальное название
Visual Performance Differences Between Clareon PanOptix and a Comparable Multifocal Intraocular Lens
Обзор
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.

Критерии участия
Критерии включения
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.

- Previous history of any ocular surgery including corneal refractive surgery.
- Participants desiring monovision.
- History of amblyopia or monofixation syndrome with poor stereoscopic vision.
- Total corneal HOA greater than 0.6um, coma less than 0.3um at 4mm-5mm scan depending on pre- op photopic topography.
- Any planned simultaneous/combined procedures at time of cataract surgery (e.g. MIGs).
- Participation in another clinical study that could interfere with the results.
- Any active ocular infection or inflammation.
