Summary

This study compares two different materials used in multifocal lenses for cataract surgery. 40 people will receive one type of lens in each eye. The goal is to see which lens provides better contrast sensitivity (ability to see differences in light and dark) 3 months after surgery. This is a small, early-stage study that may help improve lens choices for future patients.

Inclusion Criteria: * Patients ≥ 18 years of age * Patients presenting for cataract surgery in routine clinical practice and eligible for multifocal IOL implantation (toric and non-toric) * Patients with grade 2/3 cataract density and comparable visual acuity in both eyes * Patient with a pregnancy test (negative pregnancy test), if applicable * Patient with signed consent to participate in the study * Patient affiliated to a social security scheme or entitled beneficiary Exclusion Criteria: * Children \< 18 years of age * Pregnancy or breast-feeding in progress or planned during the study. * History of anterior (cornea, anterior chamber, sulcus) or posterior (uveal, vitreoretinal) segment pathology, including retinal vascular occlusive disease, retinal detachment or peripheral retinal laser photocoagulation, AMD, glaucoma. * Any inflammation of the anterior or posterior segment, whatever the etiology, and/or history of any disease with intraocular inflammatory repercussions. * Clinically significant corneal pathology (epithelial, stromal and/or endothelial) that could have an impact on visual results. * Clinically significant moderate or severe dry eye that could affect study measurements. * History of intraocular or corneal surgery (refractive or trauma-related). * Presence or history of amblyopia or monofixation syndrome. * Subjects with conditions that increase the risk of zonular disruption during the phacoemulsification procedure that may affect the centration or postoperative orientation of the IOL. * Any other planned eye surgery, including, but not limited to, limbal relaxing incision (LRI)/astigmatic keratotomy and laser refractive surgery (LASIK). * Irregular astigmatism identified by corneal topography * Patients under guardianship, curatorship or safeguard of justice, as well as pregnant or breast-feeding women (article L1121-5 of the CSP).1.1 * Patient under AME
