Trial Summary

What is the purpose of this trial?

This trial is studying the safety and performance of special artificial lenses used in cataract surgery. The study focuses on patients who have already received these lenses. These lenses help improve vision by replacing the eye's cloudy natural lens and focusing light correctly onto the retina.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What makes the Clareon PanOptix and Vivity IOLs unique compared to other vision improvement treatments?

The Clareon PanOptix IOL is unique because it offers an intermediate focal point at 60 cm, which is more comfortable for tasks like using computers and phones, and it uses ENLIGHTEN technology for better light utilization and vision in various lighting conditions. The Clareon Vivity IOL provides extended depth of focus, which helps improve vision at different distances without relying heavily on pupil size. ^{1 2 3 4 5}

Treatment Details

Interventions

• Clareon PanOptix Trifocal IOL - Non Toric (Intraocular Lens)
• Clareon PanOptix Trifocal IOL - Toric (Intraocular Lens)
• Clareon Vivity IOL - Non Toric (Intraocular Lens)
• Clareon Vivity IOL - Toric (Intraocular Lens)

Trial Overview The trial aims to assess the long-term safety and effectiveness of two types of intraocular lenses: Clareon Vivity and PanOptix, including versions designed for astigmatism (Toric). It's a follow-up study focusing on patients who already received these implants.

Participant Groups

Group I: Clareon Vivity IOL - Toric Experimental Treatment 1 Intervention

Implantation with Clareon Vivity IOLs in both eyes 3-6 months prior to enrollment, with at least one of the eyes implanted with a toric Clareon Vivity IOL.

Group II: Clareon Vivity IOL - Non Toric Experimental Treatment 1 Intervention

Implantation with Clareon Vivity IOLs in both eyes 3-6 months prior to enrollment, with at least one of the eyes implanted with a non-toric Clareon Vivity IOL.

Group III: Clareon PanOptix IOL - Toric Experimental Treatment 1 Intervention

Implantation with Clareon PanOptix IOLs in both eyes 3-6 months prior to enrollment, with at least one of the eyes implanted with a toric Clareon PanOptix IOL.

Group IV: Clareon PanOptix IOL - Non Toric Experimental Treatment 1 Intervention

Implantation with Clareon PanOptix IOLs in both eyes 3-6 months prior to enrollment, with at least one of the eyes implanted with a non-toric Clareon PanOptix IOL.

Findings from Research

The AcrySof IQ PanOptix IOL offers a more natural intermediate focal point of 60 cm, enhancing comfort for tasks like using computers, compared to traditional trifocal IOLs with an 80 cm focal point.

Clinical evidence from 12 studies indicates that the PanOptix IOL provides good visual outcomes and high spectacle independence, similar to other multifocal and extended depth of focus IOLs, but individual patient needs must be considered for optimal results.

AcrySof IQ PanOptix Intraocular Lens Versus Extended Depth of Focus Intraocular Lens and Trifocal Intraocular Lens: A Clinical Overview. Sudhir, RR., Dey, A., Bhattacharrya, S., et al.[2019]

In a study of 30 patients undergoing combined 23-gauge microincisional vitrectomy and cataract surgery, the AcrySof toric intraocular lens (IOL) significantly improved uncorrected visual acuity compared to the non-toric IOL at 1, 3, and 6 months post-surgery.

The toric IOL group also had a lower mean absolute residual refractive cylinder, indicating better astigmatism correction, while demonstrating good rotational stability, with 66.7% of lenses remaining within 5° of their intended axis after 6 months.

In a study of 100 eyes from 56 patients, the AcrySof SN60TT toric intraocular lens (IOL) showed comparable higher-order aberrations (HOAs) and optical quality to the non-toric AcrySof SN60AT IOL one year after surgery.

The toric IOL effectively corrected corneal astigmatism with a low residual refractive astigmatism of 0.44 D, indicating stable postoperative alignment and good optical outcomes.
