Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a sophisticated solution designed to enhance visual outcomes for patients undergoing cataract surgery with pre-existing astigmatism. Available in models XY1A and XY1A-SP, this lens offers advanced features tailored to meet the precise needs of ophthalmic professionals.

Key Features

• Material and Design: Crafted from glistening-free hydrophobic acrylic, the lens includes both UV and blue light filters. Its biconvex shape and unique aspheric optic design contribute to exceptional visual clarity.

• Optic and Haptic Design: The lens features a square, thin optic edge with anterior aspheric and posterior toric designs. The textured-rough haptic surface enhances rotational stability, crucial for consistent visual performance.

• Surface Treatment: Advanced surface treatments, including active oxygen processing, minimize posterior capsule opacification (PCO), ensuring long-term lens clarity.

Injector System

The preloaded multiSert™ or iSert® injector system offers versatile insertion options, allowing for both single-handed push and two-handed screw techniques. This system facilitates precise implantation through a recommended incision size of 2.20 mm, enhancing surgical efficiency.

Technical Specifications

• Dimensions: Optic diameter of 6.00 mm and an overall length of 13.00 mm.
• Power Range: Spherical power ranges from +10.00 to +30.00 D, with toric correction available in various increments to address specific astigmatic needs.

Clinical Performance

The Vivinex™ Toric IOL demonstrates outstanding rotational stability, with a median rotation of just 1.1° post-implantation. This stability is maintained across diverse ocular conditions, providing reliable visual correction.

Optical Quality

The proprietary aspheric optic design enhances optical quality by compensating for corneal spherical aberration and improving tolerance to optical imperfections. This results in superior long-term clarity and transparency.

Compatibility

Compatible with the HOYA Toric Calculator, the lens supports precise cylinder power calculations using the Abulafia-Koch Regression formula. This compatibility ensures tailored visual outcomes for each patient.

Intended Use

The HOYA Vivinex™ Toric IOL is intended for implantation during cataract surgery, offering a reliable solution for correcting corneal astigmatism. Its innovative design and robust clinical performance make it a valuable asset in achieving optimal visual results.
