Description

The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed to enhance visual outcomes for patients undergoing cataract surgery with pre-existing corneal astigmatism. Available in models XY1A and XY1A-SP, this lens offers advanced features tailored to meet the needs of ophthalmic professionals.

Advanced Optic Design

• Biconvex Structure: The lens features a biconvex optic with a square, thin, and textured edge, providing enhanced stability and precision.
• Aspheric and Toric Design: The anterior aspheric and posterior toric design helps in compensating corneal spherical aberration, improving visual clarity.
• Smooth Surface: A smooth, regular optic surface ensures minimal visual disturbances.

Material and Filtering

• Glistening-Free Acrylic: Made from hydrophobic acrylic material, the lens remains clear and free from glistening.
• UV and Blue Light Filter: Integrated filters protect the eye from harmful UV and blue light.

Haptic Design

• Textured Surface: The haptic design, made from the same acrylic material, features a textured surface for enhanced lens stability within the eye.
• Dimensions: With an optic diameter of 6.00 mm and an overall length of 13.00 mm, the lens is designed for optimal fit.

Power Specifications

• Spherical Power Range: +10.00 to +30.00 D in 0.50 D increments.
• Cylinder Power Range: At the IOL plane, 1.00 to 6.00 D, with precise increments for tailored correction.

Optical Constants

• Nominal A-Constant: 118.9, with optimized constants for various calculation formulas, enhancing surgical planning accuracy.

Injector System

• Preloaded System: The Vivinex™ iSert® or multiSert™ system allows for a seamless implantation process.
• Incision Size: Recommended incision size of 2.20 mm, facilitated by a front injector tip diameter of 1.70 mm.

Clinical Performance

Rotational Stability

• Exceptional Stability: Median rotation of 1.1° ensures the lens remains in position, with 100% of lenses showing ≤5° rotation up to six months post-surgery.

PCO Reduction

• Design Features: Active oxygen processing and a square optic edge reduce posterior capsule opacification, lowering Nd:YAG capsulotomy rates.

Clarity and Biocompatibility

• Long-Term Transparency: The glistening-free material ensures clarity, while high biocompatibility supports long-term success.

Additional Features

• Axis Orientation Marks: For precise alignment during implantation.
• Consistent Delivery: Designed for ease of use, providing outstanding delivery consistency.

Intended Use

This lens is intended for use by healthcare professionals during cataract surgery, offering a reliable solution for patients with astigmatism. Its innovative design and material properties aim to deliver superior visual outcomes and long-term satisfaction.
