Description

The HOYA Vivinex™ Toric IOL is a specialized intraocular lens designed to enhance vision clarity for patients undergoing cataract surgery with astigmatism. Available in models XY1A and XY1A-SP, this lens offers advanced features tailored for optimal performance and patient satisfaction.

Key Features

• Material: Crafted from glistening-free hydrophobic acrylic, the lens includes UV and blue light filters to protect eye health.
• Optic Design: The biconvex optic with an aspheric anterior surface and toric posterior surface ensures precise vision correction.
• Edge Design: A square, thin, textured optic edge reduces visual disturbances.
• Haptic Design: Textured-rough haptic surfaces provide enhanced lens stability within the eye.

Dimensions

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

Power Specifications

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

Rotational Stability

The lens demonstrates exceptional rotational stability, with over 96% maintaining a rotation of ≤5° post-implantation. This stability is crucial for consistent visual outcomes.

Optical Constants

• Nominal A-constant: 118.9
• Haigis, Hoffer Q, Holladay 1, and SRK/T formulas: Provided for accurate power calculation.

Injector System

The lens is preloaded in the Vivinex™ iSert® or multiSert™ injector system, facilitating a smooth implantation process. The recommended incision size is 2.20 mm.

Clinical Benefits

• Glistening-Free: Laboratory tests confirm minimal glistening formation, ensuring long-term clarity.
• PCO Reduction: Design features significantly lower posterior capsule opacification rates, reducing the need for Nd:YAG capsulotomy.
• Image Quality: The aspheric optic design enhances image quality by compensating for corneal spherical aberration.

Intended Use

This lens is intended for use by healthcare professionals to correct astigmatism during cataract surgery. It is designed for long-term transparency and stability, with specific features that may vary by region.

Additional Information

For precise cylinder power calculation, the HOYA Toric Calculator is recommended. It accounts for posterior corneal astigmatism, enhancing the accuracy of visual correction. Healthcare providers should refer to official documentation for comprehensive indications and contraindications.
