Description

The HOYA Vivinex™ Toric IOL (Model XY1AT3) is a specialized intraocular lens designed for use in cataract surgeries requiring toric correction. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional clarity and includes both UV and blue light filters for enhanced eye protection.

Optic Design

• Biconvex Aspheric Optic: Features a sharp, textured edge to minimize posterior capsule opacification (PCO) and ensure stable positioning.
• Toric Design: Provides precise correction of astigmatism, contributing to improved visual outcomes.

Haptic Design

• Textured Surface: Enhances lens stability within the eye, reducing the likelihood of rotation post-surgery.

Dimensions

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

Power Specifications

• Spherical 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, tailored to address varying degrees of astigmatism.

A-Constant

• Nominal Value: 118.9
• Optimized Constants: Available for various calculation formulas, enhancing the accuracy of lens power predictions.

Injector System

The lens is compatible with the preloaded multiSert™ or Vivinex™ iSert® injector systems, facilitating a recommended incision size of 2.20 mm. This design promotes ease of implantation and reduces surgical complexity.

Clinical Performance

• Rotational Stability: Over 96% of lenses exhibit rotation of ≤5°, ensuring consistent visual performance.
• Aspheric Optic Design: Partially compensates for corneal spherical aberration, enhancing visual clarity.

Clinical Evidence

Clinical studies demonstrate significantly lower rates of posterior capsule opacification compared to other lenses, such as AcrySof® IQ. This results in lower Nd:YAG capsulotomy rates, contributing to long-term visual satisfaction.

Calculation Tools

The HOYA Toric Calculator, including the Abulafia–Koch Regression formula, supports precise lens power calculations, accounting for posterior corneal astigmatism.

Intended Use

This lens is intended for healthcare professionals performing cataract surgeries with a need for toric correction. Its design emphasizes high clarity, rotational stability, and ease of implantation, making it a reliable choice for achieving optimal surgical outcomes.

Note: Availability may vary by country, and the lens is intended for professional use only.
