Abstract

Astigmatism management is one of the two main objectives for refractive cataract surgery and toric intraocular lens (IOL) implants are the main intraoperative cornerstone modality for the treatment of astigmatism. This chapter focuses on many key topics, such as how to determine if a toric IOL is suitable and indicated (the magnitude and the axis of astigmatism), how to determine surgically induced astigmatism, how to help those surgeons who still do not integrate posterior corneal astigmatism when they use toric IOLs, the advantages and disadvantages of direct measurement of posterior corneal astigmatism, the roles of femtosecond laser and intraoperative aberrometry related to toric IOL implantation, the reasons for toric IOL rotation and detailed discussions about how to prevent and manage misalignments, and toric IOL selection criteria for the beginners.

Key words
