Visual and refractive outcomes following implantation of a new trifocal intraocular lens.

Background: Independence from all optical aids, and freedom from unwanted symptoms, following cataract and lens surgery remains the ultimate goal of both patient and surgeon. The development of trifocal IOL technology provides an ever-increasing range of options. The purpose of our study is to understand the predictability, safety and efficacy of a new trifocal intraocular lens (IOL) following cataract or refractive lens exchange (RLE) surgery.

Evaluation of Toric Intraocular Lenses in Patients With Low Degrees of Astigmatism.

Purpose: This study aimed to describe the efficacy of toric intraocular lenses (IOLs) in patients with low degrees of corneal astigmatism.

Design: Retrospective case series was undertaken.

Methods: Patients with low amounts of corneal astigmatism who were treated with either a toric monofocal lens (SN6AT2 Toric, n = 76) or a toric multifocal lens (SND1T2 +3.
