To succeed with a toric IOL, you must align the lens with the appropriate steep meridian of astigmatism. Cataract surgery has evolved from a high-risk medical procedure that once required a hospital stay to the most commonly performed refractive procedure worldwide.

Its ubiquity has given surgeons ample opportunity to refine the outcomes with great precision. Advancements in pre-and intraoperative diagnostic testing and surgical techniques, as well as increased availability of premium intraocular lens (IOL) implants, have escalated patient expectations, thus mandating consistently accurate management of pre-existing astigmatism in order to deliver on expectations. When planning astigmatism correction, consider the magnitude and axis of…
