Assessment of Visual and Refractive Results, and Rotational Stability of the TECNIS® Eyhance Toric II 1-piece Posterior Chamber Lens in Patients With Astigmatism Undergoing Cataract Surgery: a Prospective Cohort Study - STATE

Cataract surgery is one of the most common procedures performed worldwide. Astigmatism is the most common refractive disorder in adults, hence there is a high prevalence of preexisting astigmatism in cataract patients. Access to astigmatism correction during cataract surgery allows for improved visual outcomes for patients. Toric intraocular lenses (IOLs) are the procedure of choice to correct corneal astigmatism of one diopter or more in cases undergoing cataract surgery. Rotational stability is a key factor for successful outcomes with toric IOLs. Postoperative toric IOL misalignment is the major factor responsible for suboptimal visual outcomes after toric IOL implantation. The TECNIS® Eyhance Toric II 1-piece posterior chamber lens is a new toric IOL which is FDA approved and CE marked. Marketed by Johnson & Johnson Vision, it is indicated for the visual correction of aphakia and pre-existing corneal astigmatism of one diopter or greater in adult patients with or without presbyopia in whom a cataractous lens has been removed by phacoemulsification and who desire reduction in residual refractive cylinder. No study assessing the early rotational stability of the TECNIS® Eyhance Toric II IOL has been published yet.
