Modification in Cortical Activation in Pseudophakic Patients With Visual Difficulties After a Multifocal Implantation

Modification in Cortical Activation by Functional Magnetic Resonance Imaging (fMRI) in Pseudophakic Patients With Visual Difficulties After a Multifocal Implantation

This study will highlight differences in cortical activation between asymptomatic and symptomatic patients.

Inclusion Criteria:

• Cataract surgery with an bilateral multifocal lens implant Restor

Symptomatic patients :

• Symptomatic bilateral visual difficulties for 3 months or more after the intervention which impact the daily activity

Asymptomatic patients :

• No visual complaint for 3 months or more after the intervention

Exclusion Criteria:

• Patients with ophthalmology disorders
• Contra indication for fMRI
