Capsular Tension Rings in Intraocular Lens Rotation

\*\*Patients must be able to get care at Nellis Air Force Base (a military installation) in order to participate in this study\*\* Inclusion Criteria: * Active duty and DoD beneficiaries aged 30 years or older undergoing cataract surgery * Corneal astigmatism ≥ 1.0 D and a surgical plan that includes a toric intraocular lens for astigmatism correction. (The lens used will be the TECNIS IOL. It will be used on label) * No observed zonular or capsular problems prior to, or at the time of, capsular tension ring insertion Exclusion Criteria: * Patients undergoing cataract surgery who do not have corneal astigmatism ≥1.0 D. * Any observed zonular or capsular problems prior to, or at the time of, capsular tension ring insertion. * Pre-existing ocular conditions, including:Pre-existing ocular conditions, including: * Pseudoexfoliation syndrome in one or both eyes * Prior incisional ocular surgery * Lens subluxation * Poor dilation or inability to position at the slit lamp (making postoperative outcome measurements difficult or impossible) * Plans for extensive travel or to move away during the postoperative evaluation period * Other conditions that would influence the capsule or lens positioning * Surgical plan to include other procedures at the time of initial cataract surgery, such as Limbal Relaxing Incisions (LRIs), Micro-Incisional Glaucoma Surgery (MIGS), etc.
