Comparison of Visual Outcomes of Two Trifocal IOLs.

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Optometry

Background:

• Cataract surgery is a common procedure to restore vision.
• Trifocal intraocular lenses (IOLs) aim to provide clear vision at multiple distances, reducing spectacle dependence.
• Comparing the visual performance of different trifocal IOL models is crucial for clinical decision-making.

Purpose of the Study:

• To compare the visual outcomes of bilateral implantation of two commercially available trifocal intraocular lenses (IOLs): AcrySof IQ PanOptix and AcrivaUD Trinova.
• To evaluate distance, intermediate, and near visual acuities, as well as other visual quality parameters.

Main Methods:

• A single-center, randomized trial involving 71 adult patients (142 eyes).
• Patients were randomized 1:1 to receive either PanOptix or Trinova IOL implantation in both eyes.
• Visual acuities, defocus curves, refractive outcomes, contrast sensitivity, and patient satisfaction were assessed at 3 months post-implantation.

Main Results:

• The PanOptix IOL group showed significantly better distance-corrected intermediate visual acuity (P = .0304).
• Uncorrected intermediate and near visual acuities were significantly better in the PanOptix IOL group (both P < .001).
• No significant differences were observed in other outcomes, and no adverse events were reported.

Conclusions:

• The PanOptix IOL offers superior intermediate and near visual performance compared to the Trinova IOL.
• This suggests the PanOptix IOL is a favorable choice for patients desiring spectacle independence.
• Further research may explore long-term outcomes and patient-reported quality of vision.
