Summary

This prospective comparative cohort study evaluates and compares postoperative rotational stability and time-course dynamics of three commercially available toric intraocular lenses (TECNIS Toric II \[ZCU\], AcrySof IQ Toric, and AT TORBI 709M) after phacoemulsification cataract surgery. Rotation is quantified by registering postoperative retroillumination photographs to the end-of-surgery baseline using iris/scleral landmarks, with follow-up at postoperative day 1, day 3, week 1, week 2, month 1, and month 3. Associations between rotational outcomes and ocular biometric parameters are analyzed using linear mixed-effects models to inform individualized IOL selection and perioperative management.
