Clinical and aberrometric evaluation of a new extended depth-of-focus intraocular lens based on spherical aberration.

Purpose: To compare the refractive, visual, and aberrometric results with a new extended depth-of-focus intraocular lens (EDOF IOL) based on alternating positive and negative spherical aberration in the central 3.0 mm optical zone and an aspheric monofocal IOL of the same platform.

Setting: Ophthalmology, University Hospital of Verona, Italy.

Visual acuity and refraction with a diffractive multifocal toric intraocular lens.

Purpose: To evaluate clinical outcomes and optical performance of the AT Lisa 909M diffractive multifocal toric intraocular lens (IOL).

Setting: Multicenter study.

Design: Cohort study.
