Introduction: With the increasing demand for refractive cataract surgery globally, toric Intraocular Lenses (IOL) have become the preferred choice for surgeons to correct corneal astigmatism of 1D or more during cataract surgery, and to provide patients spectacle free distance vision. They come with its own set of challenges; Inaccurate biometry, underestimating the Posterior corneal astigmatism, wrong axis marking, surgically induced astigmatism, postoperative rotation of these lenses may result in residual cylindrical errors and poor uncorrected visual acuity resulting in patient dissatisfaction. Methods: We reviewed existing literature to identify the challenges associated with patient selection, preoperative evaluation, assessment of Posterior corneal astigmatism, accurate biometry, precise marking of axis, implantation of toric Intraocular Lenses and postoperative lens rotation and measures to optimize the outcome. Results: We present a brief overview of toric IOLs currently available along with newer biometry platforms which take into account the surgically induced astigmatism, Posterior corneal curvature as well as the effective lens position to achieve perfect power calculation. Newer image recognition devices and intraoperative aberrometry not only provides mark less IOL alignment but also aid in planning the incisions, capsulorhexis size and optimal IOL centration. Conclusions: Carefully planned and executed cataract surgery with toric IOL implant can greatly optimize the visual outcome and improve patient’s quality of life.
