Corneal astigmatism occurs due to the inequality of the corneal curvatures and needs to be addressed to achieve spectacle independence and optimal vision. Corneal astigmatism can be calculated by corneal topography, corneal tomography, keratometry, and intraoperative aberrometry. Toric intraocular lenses (IOLs) are considered the most predictive way of correcting corneal astigmatism in a patient undergoing cataract surgery, as they may correct astigmatism as low as 0.75 diopters. Monofocal and multifocal toric IOLs are available and are chosen based on the patient’s expectations. Toric IOLs are unsuitable for patients with pre-existing posterior segment pathology, zonular instability, and irregular astigmatism. The most common concern is the postoperative misalignment of the IOL, which can be prevented by washing the viscoelastic from the anterior chamber and the capsular bag to avoid postoperative rotation. This activity reviews the indications of toric IOLs and highlights the role of ophthalmologists, optometrists, and paramedical staff in evaluating and treating corneal astigmatism.
