Who can join

Age: 40 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• 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.

You may not qualify if…

• 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.
