IOL Power Calculation for Toric IOLs and How to Battle Astigmatism

Astigmatism, even at low levels (0.75 diopters (D) or more), can significantly affect postoperative uncorrected visual acuity and patient satisfaction. Toric intraocular lenses (IOLs) provide an effective solution when paired with accurate biometry, proper formula use, refined surgical planning, and attention to platform-specific nuances. This chapter reviews practical strategies to optimize toric outcomes in daily practice [1, 2].
