Multicenter Retrospective Analysis of Intraoperative Aberrometer Measurements and Associated Visual Outcomes with a...

Area of Science:

• Ophthalmology
• Refractive Surgery
• Intraocular Lenses

Background:

• Clareon monofocal intraocular lenses (IOLs) are widely used for vision correction.
• Intraoperative aberrometry (IA) offers real-time refractive data during cataract surgery.
• Assessing real-world performance of IOLs with IA is crucial for optimizing surgical outcomes.

Purpose of the Study:

• To evaluate the real-world effectiveness of Clareon monofocal non-Toric and Toric IOLs.
• To assess the performance of intraoperative aberrometry (WaveTec ORA System) in conjunction with these IOLs.

Main Methods:

• Retrospective analysis of anonymized data from a multicenter US study.
• Included patients implanted with Clareon ultraviolet-absorbing (UVA) monofocal or monofocal Toric IOLs.
• Utilized WaveTec ORA System data and postoperative corrected distance visual acuity (CDVA) at 1 month to 3 years.

Main Results:

• 98.4% of eyes achieved CDVA of 20/40 or better.
• 93.9% of emmetropia-targeted eyes achieved uncorrected distance visual acuity (UDVA) of 20/40 or better.
• Mean residual refractive cylinder was 0.40 D for Toric IOLs; mean prediction error was -0.10 D.

Conclusions:

• Clareon UVA IOLs combined with WaveTec ORA IA achieve high rates of good visual acuity.
• ORA may optimize IOL power calculation and axis positioning, leading to improved refractive outcomes.
• Minimal residual refractive error and enhanced target accuracy were observed.
