Hypothesis

What are the risk factors for photic phenomena in eyes with two types of presbyopia-corrected intraocular lenses?

Conclusion

The study found that the Synergy group experienced stronger photic phenomena compared to the PanOptix group, particularly in cases with larger pupil diameters.

Supporting Evidence

  • The Synergy group showed larger and stronger halos and starbursts compared to the PanOptix group.
  • Postoperative halo brightness was positively correlated with corneal coma aberration in the PanOptix group.
  • The study used a quantitative assessment method for photic phenomena using the PPT.

Takeaway

This study looked at how different types of eye lenses affect light effects after surgery, finding that one type causes more noticeable light effects than the other, especially in people with larger pupils.

Methodology

Patients with PanOptix and Synergy IOLs underwent the Photic Phenomena Test (PPT) between 1 and 3 months after cataract surgery to assess photic phenomena.

Potential Biases

Potential bias due to the exclusion of patients with certain eye conditions and the subjective nature of patient-reported outcomes.

Limitations

The study did not investigate the long-term risk of photic phenomena and relied on pupil diameter at the time of PPT measurement post-surgery.

Participant Demographics

The PanOptix group had a mean age of 65.7 years, while the Synergy group had a mean age of 61.9 years.
