Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL) is expertly crafted to address the needs of patients undergoing cataract surgery who also have pre-existing corneal astigmatism. This advanced lens is designed to provide clear vision by correcting astigmatism, offering significant benefits to both patients and healthcare professionals.

Material and Design

• Material: The lens is made from glistening-free hydrophobic acrylic, ensuring long-term clarity. It includes UV and blue light filters to protect the eye from harmful light exposure.
• Optic Design: Features a biconvex shape with a square, thin, and textured optic edge. The anterior surface is aspheric, while the posterior surface is toric, enhancing visual performance by compensating for corneal spherical aberration.
• Haptic Design: The C-loop design with a textured-rough surface ensures stable positioning within the eye.

Surface Treatments

The lens undergoes active oxygen processing on its posterior surface, resulting in a smooth and regular optic surface. The square edge design is intended to reduce posterior capsule opacification (PCO), a common post-surgery complication.

Rotational Stability

The Vivinex™ Toric IOL demonstrates exceptional rotational stability, with over 96% of lenses rotating 5 degrees or less post-implantation. This stability is crucial for consistent astigmatism correction, maintaining optimal visual outcomes.

Technical Specifications

• Model Numbers: XY1A, XY1A-SP
• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm
• Power Range: +10.00 to +30.00 D in 0.50 D increments
• Cylinder Power: Available in various increments to suit individual patient needs

Delivery System

The lens is preloaded in the multiSert™ or Vivinex™ iSert® injector system, allowing for versatile insertion techniques. The injector tip's outer diameter is 1.70 mm, with a recommended incision size of 2.20 mm, facilitating minimally invasive surgery.

Clinical Benefits

The HOYA Vivinex™ Toric IOL is designed to minimize PCO and offers significantly lower PCO scores compared to other IOLs. Its glistening-free material ensures clarity, while outstanding rotational stability provides reliable astigmatism correction. These features contribute to improved image quality and patient satisfaction.

Intended Use

This lens is intended for use by healthcare professionals during cataract surgery, providing a tailored solution for patients with astigmatism. The precise engineering and innovative design of the HOYA Vivinex™ Toric IOL make it a valuable tool in achieving superior visual outcomes.
