Toric intraocular lenses: advancements in astigmatism correction.

PURPOSE OF REVIEW: Toric intraocular lenses (IOL) predictably correct corneal astigmatism and are an important part of the cataract and refractive surgeon's toolbox.

RECENT FINDINGS: Advances in toric IOL technology, preoperative biometry, IOL power calculations, and IOL alignment have resulted in excellent visual outcomes and achievement of spectacle independence. Despite these advancements, the primary challenges faced in toric IOL use remain choosing the optimal IOL toricity and properly aligning the IOL.

SUMMARY: Toric IOL are an effective way to correct corneal astigmatism, and advancements in lens selection and design have improved their functionality for patients. This review summarizes these advances and reports on upcoming technologies.
