Eligibility criteria

• Inclusion Criteria:
• • Patient presenting for a request for cataract surgery in current practice: phacoemulsification followed by classic implantation of an IOL with small incision size (\< 2.2mm)
• • Calculated power of IOL is between 10.0 and 30.0 diopters (D) in 0.5D steps to target emmetropia (0.0 +/- 0.5D)
• • Patients with corneal astigmatism \> 0.5D and who can receive an implant with a toricity between T2 and T6, i.e. with astigmatism between +0.5D and +2.5D.
• • If both eyes have astigmatism, the eye under study will be the right eye
• • Patient having been informed and not objecting to their participation.
• Exclusion Criteria:
• • Pregnancy or breastfeeding while conducting the study
• • Person under the age of 18

• • Any inflammation of the anterior or posterior segment, whatever its etiology or history of disease, which may lead to an inflammatory reaction
• • Clinically significant corneal pathology (epithelial, stromal, or endothelial that could affect visual outcome)
• • Clinically significant severe dry eye disease that may affect visual calculations and measurements
• • History of refractive surgery
• • Amblyopia or monofixation syndrome
