Comparing Rotational Stability Over Time Between Four Monofocal Toric Intraocular Lenses.

Purpose: To evaluate the rotational stability of four different monofocal toric intraocular lenses (IOLs) from surgery to 4-6 months postoperative.

Methods: This was a subset of data from a prospective multi-center randomized clinical study. High resolution retro-illuminated images of eyes implanted with four different toric IOLs were obtained immediately after surgery, and at 1 day, 1 week, 1 month and 4-6 months after surgery.

Comparison of Visual Acuity Outcomes of Enhanced Monofocal Versus Standard Monofocal Intraocular Lenses from a Randomized, Multicenter, Active-Controlled Trial.

Purpose: To compare visual performance of the Vivinex Impress enhanced monofocal intraocular lens (IOL) (HOYA Surgical Optics) with the Acrysof IQ monofocal IOL (Alcon Laboratories, Inc).

Methods: In this multicenter, active-controlled trial, participants were randomized 2:1 to bilateral implantation with the enhanced monofocal (test) or standard monofocal (control) IOL and examined through 12 months postoperatively for visual acuities, refractive outcomes, defocus curves, and pupil diameters.

Results: Ninety-eight test and 46 control participants completed testing for the first implanted eye.

Customizing Clinical Outcomes with Implantation of Two Diffractive Trifocal IOLs of Identical Design but Differing Light Distributions to the Far, Intermediate and Near Foci.

Purpose: To evaluate clinical outcomes after bilateral or contralateral implantation of the Gemetric™ (G) and Gemetric™ Plus (GPlus) diffractive trifocal intraocular lenses (IOLs).

Methods: This was a prospective, randomized, multi-center open-label study comparing clinical results and subjective patient responses around 6 months after implantation of the study lenses (toric and non-toric) in three different groups (bilateral G, bilateral GPlus and contralateral G/GPlus implantation). Results included the manifest refraction, uncorrected and distance corrected monocular and binocular visual acuity (VA) at distance, intermediate and near; the defocus curve; contrast sensitivity; and patient reported outcomes regarding spectacle independence, satisfaction and visual disturbances.
