ABSTRACTPurpose: To compare the near visual acuity sharpness between the monofocal and multifocal lens.
Method: Comparative, prospective, longitudinal and experimental clinic trial, divided in two groups: Groupo one: 11 patients with silicon monofocal lens S140 and the second group 11 patients with Amo-Array silicon multifocal. We included patients older than 40 years old, males and females submitted to cataract surgery with phacoemulsification and IOL implantation. All patients were evaluated near and far visual acuity pre and postoperative, contrast sensitivity, topography and specular microscopy.
Results: The mean age was very similar in both groups. There was no difference at one month in far visual acuity: Group one 20/50 to 20/30 and group two 20/30 to 20/25. There was statistical significant difference in near visual acuity: Group I J6 and J3 in group II. Contrast sensitivity and endothelial cell lost were similar in both groups.
Conclusions: Most patients with multifocal lens had an acceptable far and near vision; nevertheless we need longer follow up and more patients to have more accurate results.
