Description

The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed for patients undergoing cataract surgery who also require astigmatism correction. Available in models XY1A and XY1A-SP, this lens offers advanced features tailored to enhance visual outcomes and surgical precision.

Advanced Optic Design

• Biconvex Optic: Features a thin, textured edge with an anterior aspheric design to partially compensate for corneal spherical aberration, improving image quality.
• Posterior Toric Design: Enhances visual clarity and reduces optical aberrations.

Material and Filtering

• Hydrophobic Acrylic: Constructed from glistening-free Vivinex™ material.
• Integrated Filters: Includes UV and blue light filters to protect the eye.

Haptic Design

• Textured Surface: Provides enhanced stability post-implantation.
• Dimensions: Optic diameter of 6.00 mm and overall length of 13.00 mm.

Power Specifications

• Spherical Power Range: +10.00 to +30.00 diopters in 0.50 D increments.
• Toric Power Range: Cylinder power at IOL plane from 1.00 to 6.00 D, with precise increments for tailored correction.

Rotational Stability

• High Stability: Median rotation of 1.1° with 100% of lenses showing ≤5° rotation up to six months post-surgery.
• Consistent Performance: Over 96% of lenses maintain stability even in eyes with high axial lengths.

Posterior Capsule Opacification (PCO) Resistance

• Design Features: Active oxygen processing and a square optic edge reduce PCO.
• Clinical Outcomes: Lower PCO and Nd:YAG capsulotomy rates compared to other IOLs.

Injector System

• Preloaded Systems: Vivinex™ iSert® or multiSert™ systems with a front injector tip diameter of 1.70 mm.
• Incision Size: Recommended at 2.20 mm, supporting both single-handed and two-handed injection techniques.

Optical Constants

• Nominal A-constant: 118.9, with optimized constants for various calculation formulas such as Haigis and SRK/T.

Clinical Benefits

• Image Quality: Proprietary aspheric design enhances image quality and tolerance to optical aberrations.
• Long-term Clarity: Glistening-free material ensures clarity.
• PCO Resistance: Supported by clinical data for reduced PCO incidence.

Intended Use

This lens is intended for implantation by healthcare professionals during cataract surgery, providing reliable astigmatism correction and long-term visual benefits. For comprehensive usage instructions, refer to the official Instructions For Use.
