Description

The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed for patients undergoing cataract surgery who also require astigmatism correction. This advanced lens offers a range of features tailored to enhance visual outcomes and surgical precision.

Advanced Optic Design

• Biconvex Structure: The lens features a biconvex optic with a square, thin, and textured edge.
• Aspheric and Toric Surfaces: The anterior surface is aspheric, while the posterior surface is toric, aiding in the correction of corneal spherical aberration and improving tolerance to optical imperfections.
• Axis Orientation Marks: These are located on the posterior surface for precise alignment.

Material and Filtering

• Glistening-Free Acrylic: Made from hydrophobic acrylic material, ensuring long-term clarity.
• UV and Blue Light Filters: Integrated filters provide additional protection for the eye.

Haptic Design

• Textured Surface: The haptic design includes a textured-rough surface for enhanced stability post-implantation.
• Consistent Material: Both the optic and haptic are made from the same acrylic material.

Dimensions and Power Range

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm
• Spherical Power: Ranges from +10.00 to +30.00 diopters in 0.50 D increments.
• Toric Power: Cylinder power at the IOL plane ranges from 1.00 to 6.00 D.

Rotational Stability

The lens demonstrates exceptional rotational stability, with a median rotation of 1.1°. Clinical results show that over 96% of lenses rotate ≤5° post-implantation, ensuring consistent astigmatism correction.

Injector System

The lens is preloaded in the Vivinex™ iSert® or multiSert™ injector system, allowing for:

• Single-Handed or Two-Handed Injection: The multiSert™ system provides flexibility.
• Small Incision Compatibility: Recommended incision size is 2.20 mm, with a front injector tip diameter of 1.70 mm.

Optical Constants

The lens supports various calculation formulas with specific optical constants, enhancing precision in surgical planning. It is compatible with the HOYA Toric Calculator, which uses advanced regression formulas for accurate power calculations.

Clinical Benefits

• High Rotational Stability: Proven in clinical settings for consistent performance.
• Reduced Posterior Capsule Opacification: The square edge design minimizes PCO, leading to lower Nd:YAG capsulotomy rates compared to other lenses.
• Biocompatibility: Confirmed through clinical studies, ensuring long-term clarity and performance.

Intended Use

The HOYA TORIC IOL VIVINEX ISERT is intended for implantation by healthcare professionals during cataract surgery, providing reliable astigmatism correction and improved visual outcomes for patients.
