Brief Summary:
Multifocal lens allow most patients to be spectacle-free after cataract surgery. Most studies published up-to-date have focused on visual acuity, but not on patient-reported outcomes. Since some patients with very good postoperative visual acuity report being very uncomfortable after surgery, the aim of this study is to evaluate if patient satisfaction is correlated with other outcomes, such as low-contrast visual acuity, contrast sensitivity, photic phenomena and ability to tolerate defocus. Patients who have undergone surgery with bilateral multifocal intraocular lens implantation will be carefully evaluated 3 months after surgery to try to determine the factors that correlate with patient reported outcomes as evaluated with the Catquest SF-9 questionnaire.
