The study is a prospective, subject-blinded investigation of whether implanting capsular tension rings with intraocular lenses affects rotational stability of the lens. Lens Selection: The patients will undergo standard of care preoperative measurements and planning. The surgeon will evaluate preoperative measurements and use lens calculations, as well as a discussion with the patient, to identify whether a toric lens will be used and to determine the IOL power, cylinder, and target axis (standard of care). Preoperative measurements will be taken using IOL-Master 700, with the addition of the Pentacam and automatic keratometry as needed (standard of care). The toric lens used will be the TECNIS IOL. It will be used on label (standard of care). Randomization: Each eye undergoing cataract surgery will be randomized into a control or treatment group. If both eyes meet enrollment criteria, then each eye will be randomized independently. Control group: toric IOL only Treatment group: toric IOL plus capsular tension ring
