Capsular Tension Rings in Intraocular Lens Rotation

Intervention. Toric IOL + CTR. Whether the subject receives 14, 14A, or 14C is an either or scenario depending on the eye's axial length and is a single intervention: Axial length \> 28.0 mm: CTR model 14A Axial length 24.0-28.0 mm: CTR model 14C Axial length \< 24.0 mm: CTR model 14 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).

Control. Toric IOL only. Standard of care cataract surgery without placement of a capsular tension ring. 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).
