The main goal of a presbyopic patient is to reduce dependence on optical aids and improve both distance and near vision as well as the range of clear vision. Several studies report good safety, predictability, and efficacy outcomes in the implantation with monofocal, toric and multifocal intraocular lenses (IOLs) after refractive lens exchange (RLE). Patients with hybrid spherical IOLs show good distance and near visual acuity with some restrictions at intermediate distances, and visual complaints regarding glare and haloes. Aspheric IOLs were designed to introduce negative spherical aberration to compensate for the positive spherical aberration of the cornea. These new IOL designs with aspheric profiles were developed with the goal of reducing unwanted visual phenomena associated with multifocal IOL performance. Preliminary reports show good distance and near vision as well as functional intermediate vision. The purpose of this study was to assess the efficacy, safety, and predictability in patients who had undergone bilateral implantation of the AcrySof® ReSTOR® SN6AD3 IOL in the capsular bag after RLE.
