About this trial
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.
Eligibility criteria
Qualifiers
Adults aged 18 years or older with age-related cataract scheduled for phacoemulsification cataract surgery.
Presence of regular corneal astigmatism requiring toric intraocular lens implantation.
Eligible for implantation of one of the three study toric intraocular lenses based on preoperative evaluation.
Ability to understand the study procedures and provide written informed consent.
Disqualifiers
History of prior ocular surgery in the study eye.
History of ocular trauma in the study eye.
Irregular corneal astigmatism or corneal pathology affecting reliable biometric measurement.
Intraoperative complications, including anterior capsular tear or posterior capsular rupture.
