描述
Inclusion Criteria:
- Adult cataract patients aged 40 years and older scheduled for age related cataract surgery in both eyes.
- Ability to understand and sign an ethics committee-approved informed consent form.
- Willingness and ability to attend all scheduled study visits as required by the protocol.
- Postoperative potential visual acuity of 20/25 or better in each eye, as determined by the investigator.
- Preoperative corneal astigmatism that can be corrected with a T3 or T4 toric IOL, or with a spherical IOL and LRIs or AKs resulting in a predicted postoperative astigmatism of less than 0.5 diopters (D).
- Ability to understand and complete questionnaires.
Exclusion Criteria:
- Women who are pregnant, planning to become pregnant during the study, or breastfeeding.
- Ocular conditions that could confound study results, including moderate to severe corneal pathology, irregular astigmatism, moderate to severe dry eye, preexisting retinal diseases such as macular degeneration or diabetic retinopathy.
- Any form of confirmed glaucomatous damage (ie, mild, moderate, or severe glaucoma).
- Participation in another clinical study that could interfere with the results.
- Systemic conditions that may affect healing or visual outcomes (e.g., uncontrolled diabetes mellitus, certain autoimmune disorders).
- Subjects with nystagmus, strabismus, zonular laxity or dehiscence, and pseudoexfoliation.
- Prior ocular surgery (except for uncomplicated cataract surgery in the fellow eye).
- Participants desiring monovision.
- Any active ocular infection or inflammation (except for routine post-operative inflammation in the fellow eye)
- Psychiatric or cognitive disorders that may impair the ability to comply with study procedures or provide accurate self-assessments.
- RMS total higher-order aberrations (HOAs) >0.70 µm or coma >0.40 µm as measured by tomography or topography with a 4 mm pupil setting.
