Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a specialized lens designed for patients undergoing cataract surgery who also require correction for pre-existing corneal astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional clarity and long-term visual performance.

Key Features

• Rotational Stability: Engineered for high rotational stability, ensuring consistent astigmatism correction.
• Optic Design: Features a biconvex optic with an anterior aspheric surface and a posterior toric surface to enhance image quality and reduce optical aberrations.
• Surface Treatment: Active oxygen processing provides a smooth surface and square optic edge, significantly reducing posterior capsule opacification (PCO).

Light Filtering

The lens incorporates UV and blue light filtering, protecting the eye from harmful light exposure while maintaining visual clarity.

Haptic Design

• Configuration: C-loop configuration with a textured-rough surface for enhanced stability within the eye.
• Dimensions: Optic diameter of 6.00 mm and an overall length of 13.00 mm.

Power Range

• Spherical Power: Available from +10.00 to +30.00 diopters (D) in 0.50 D increments.
• Cylinder Power: Ranges from 1.00 to 6.00 D at the IOL plane, with precise increments for tailored correction.

Optical Constants

Provides optimized constants for various formulas including Haigis, Hoffer Q, Holladay 1, and SRK/T, ensuring accurate lens power calculations.

Injector System

Delivered via the preloaded multiSert™ or iSert® injector system, allowing for a recommended incision size of 2.20 mm. The system offers single-handed push and two-handed screw injection options for consistent and precise implantation.

Clinical Benefits

• Image Quality: Aspheric optic design improves image quality and reduces aberrations.
• PCO Reduction: Square optic edge design minimizes PCO, leading to lower Nd:YAG capsulotomy rates compared to other IOLs.

Intended Use

This lens is intended for use by healthcare professionals during cataract surgery, providing significant visual benefits for patients with astigmatism. Availability may vary by country, and healthcare providers should refer to the Instructions For Use for full indications and contraindications.
