Real-World Visual Outcomes and Rotational Stability of a Monofocal Toric Intraocular Lens

Area of Science:

• Ophthalmology
• Biomedical Engineering

Background:

• Cataract surgery is a common procedure to restore vision.
• Toric intraocular lenses (IOLs) are used to correct astigmatism during cataract surgery.
• The Clareon aspheric monofocal toric IOL with the AutonoMe delivery system is a newer option for patients.

Purpose of the Study:

• To evaluate the real-world visual outcomes (distance and intermediate acuity) of the Clareon aspheric monofocal toric IOL.
• To assess the rotational stability of the IOL post-implantation.
• To document any adverse events associated with the IOL and delivery system.

Main Methods:

• A retrospective review of surgical charts from January 2021 to October 2023.
• Inclusion of adult patients who received Clareon aspheric monofocal toric IOLs (CNA0T2-CNA0T6).
• Data collection included visual acuity (CDVA, UIVA, DCIVA), residual astigmatism, and IOL rotation up to one month postoperative.

Main Results:

• Excellent corrected distance visual acuity (CDVA) of -0.01 ± 0.07 logMAR at one month.
• Functional intermediate visual acuity (UIVA: 0.22 ± 0.14 logMAR, DCIVA: 0.24 ± 0.12 logMAR).
• Minimal absolute IOL rotation (1.02 ± 1.21°) and very low residual astigmatism (<0.01D).

Conclusions:

• The Clareon aspheric monofocal toric IOL demonstrates excellent visual outcomes for distance vision and astigmatism correction.
• The IOL provides functional intermediate visual acuity with high rotational stability.
• The study reported minimal adverse events, indicating a favorable safety profile.
