Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a specialized medical device designed for implantation during cataract surgery. It addresses pre-existing corneal astigmatism, offering a tailored solution for improved visual outcomes. This lens is crafted from glistening-free hydrophobic acrylic material, ensuring long-term clarity and durability.

Advanced Optic Design

• Aspheric Surface: The anterior aspheric surface enhances image quality by compensating for corneal spherical aberration.
• Toric Surface: The posterior toric surface effectively corrects astigmatism.
• Integrated Filters: Includes UV and blue light filters for added eye protection.

Structural Features

• Edge Design: The lens features a square, thin, and textured optic edge with a smooth surface, processed with active oxygen to minimize posterior capsule opacification (PCO).
• Haptic Design: The C-loop haptic design with a textured surface provides enhanced stability. Axis orientation marks ensure precise alignment during implantation.

Dimensions

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm (with some models ranging from 12.5 mm to 13.00 mm)

Power Specifications

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

Injector System

The lens comes with a preloaded multiSert™ or iSert® injector system, allowing for consistent and controlled delivery. The system offers flexible injection options and is designed for a recommended incision size of 2.20 mm.

Optical Constants

• Nominal A-constant: 118.9
• Optimized Constants: Provided for various calculation methods, enhancing surgical precision.

Clinical Performance

• Rotational Stability: Demonstrates outstanding stability with a median rotation of 1.1°, ensuring consistent astigmatism correction.
• Design Benefits: The aspheric optic design reduces PCO formation and is tolerant to optical imperfections like coma.

Indications

This lens is intended for use by healthcare professionals during cataract surgery in patients with astigmatism. Some models may offer additional features like trifocal capabilities for comprehensive vision correction.

The HOYA Vivinex™ Toric IOL stands out for its innovative design and reliable performance, making it a valuable tool in achieving optimal visual outcomes post-surgery.
