Visual Quality, Patient Satisfaction, and Photic Phenomena With a Diffractive Intraocular Lens and Its New Evolved...

Area of Science:

• Ophthalmology
• Biomaterials Science

Background:

• Intraocular lenses (IOLs) are crucial for vision restoration after cataract surgery.
• Diffractive IOLs offer spectacle independence but can cause photic phenomena.
• Evaluating IOL material impact on visual outcomes and patient experience is essential.

Purpose of the Study:

• To compare visual quality, patient satisfaction, and photic phenomena between two similar diffractive IOLs made from different materials.
• To assess long-term outcomes (3 and 12 months) following implantation of AcrySof PanOptix IOL versus Clareon Pan-Optix IOL.
• To investigate the effect of IOL material on posterior capsule opacification and glistening.

Main Methods:

• Retrospective observational study involving 59 patients implanted with either AcrySof PanOptix or Clareon Pan-Optix IOL.
• Binocular contrast sensitivity measured at 3 and 12 months post-surgery.
• Patient-reported outcomes included dysphotopsias, night driving difficulties, spectacle independence, and satisfaction (Catquest 9-SF).

Main Results:

• Both IOL groups demonstrated stable contrast sensitivity and reduced halos/night driving issues by 12 months.
• High and comparable patient satisfaction rates (>85% spectacle independence) were observed in both groups.
• Posterior capsule opacification rates were similar; Clareon IOL showed significantly less glistening (90% vs 64%).

Conclusions:

• Both AcrySof and Clareon PanOptix diffractive IOLs provide excellent visual outcomes and patient satisfaction up to 12 months.
• The Clareon IOL material appears to maintain IOL transparency better, with reduced glistening.
• These findings support the use of both IOLs, with potential advantages for the Clareon material in long-term clarity.
