Purpose of review To outline current options for managing astigmatism during cataract surgery and update readers on new techniques for improving the final refractive outcome in these patients. Recent findings Recent studies continue to show the effectiveness of peripheral corneal relaxing incisions (PCRIs) for correcting astigmatism in combination with monofocal, multifocal, and toric intraocular lens (IOL) implants. The options in toric IOLs are expanding. Intraoperative aberrometry is a new tool that can improve the accuracy of PCRIs and toric IOLs. Summary PCRIs and toric IOLs are currently the two main options for astigmatism management during cataract surgery. Refractive outcomes are improved by new techniques, which refine the effectiveness and accuracy of these two options.
