Description

The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed for implantation during cataract surgery. It addresses pre-existing corneal astigmatism in adult patients, providing a tailored solution for improved visual outcomes. This lens is intended for use by healthcare professionals and is delivered through the Vivinex™ iSert® or multiSert™ preloaded injector system.

Advanced Optic Design

• Biconvex Optic: Features a square, thin, and textured edge for enhanced performance.
• Aspheric Anterior Surface: Improves image quality and compensates for corneal spherical aberration.
• Posterior Toric Design: Corrects astigmatism effectively, with axis orientation marks for precise alignment.

Material and Filtering

Crafted from glistening-free hydrophobic acrylic, the lens includes integrated UV and blue light filters, ensuring optical clarity and protection.

Haptic Design

The lens haptics share the same hydrophobic acrylic material and feature a textured surface, promoting stability within the eye.

Dimensions

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm

Power Specifications

• Spherical Power: Ranges from +10.00 to +30.00 diopters in 0.50 D increments.
• Cylinder Power: At the IOL plane, ranges from 1.00 to 6.00 D, with specific increments for precise correction.

Optical Constants

Includes nominal A-constant and optimized constants for accurate lens power calculation across various formulas.

Injector System

The preloaded system features a front injector tip with an outer diameter of 1.70 mm, recommending an incision size of 2.20 mm for optimal insertion.

Clinical Performance

• Rotational Stability: Demonstrates minimal rotation post-surgery, maintaining alignment within 5° for the majority of lenses.
• Optical Clarity: The material remains glistening-free, enhancing visual quality.

Posterior Capsule Opacification (PCO) Reduction

The lens design includes active oxygen processing and a square optic edge, significantly reducing PCO and related interventions compared to other IOLs.

Image Quality

Proprietary aspheric optic design enhances tolerance to optical aberrations, providing superior image quality.

Indications

Suitable for adult cataract patients with regular corneal astigmatism greater than 0.75 D. It is intended for implantation in the capsular bag during surgery by experienced ophthalmic surgeons.

Additional Features

Cylinder power calculation is supported by the HOYA Toric Calculator, utilizing advanced regression formulas for precise outcomes. For comprehensive indications and contraindications, practitioners should refer to the Instructions For Use.
