Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL), Model XY1A-SP, is a specialized lens designed for patients undergoing cataract surgery who also have pre-existing corneal astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional clarity and durability, featuring both UV and blue light filtering properties.

Optical Design

• Aspheric and Toric Surfaces: The lens includes a biconvex optic with an aspheric anterior surface and a toric posterior surface, enhancing visual performance by compensating for corneal spherical aberrations.
• Edge Design: A square, thin, and textured optic edge helps reduce posterior capsule opacification (PCO), contributing to long-term visual clarity.

Stability and Performance

• Haptic Design: The C-loop haptic configuration with a textured-rough surface ensures high rotational stability, with over 96% of lenses maintaining a rotation of ≤5° post-implantation.
• Dimensions: The optic diameter is 6.00 mm, with an overall length of 13.00 mm, suitable for precise implantation.

Power Range

• Spherical Power: Available from +10.00 to +30.00 D in 0.50 D increments.
• Cylindrical Power: Ranges from 1.00 to 6.00 D, tailored to correct astigmatism effectively.

Surface Treatment

Active oxygen processing provides a smooth lens surface, while the square optic edge design further minimizes PCO. Clinical studies indicate significantly lower PCO scores and reduced Nd:YAG capsulotomy rates compared to other IOLs.

Injector System

The lens is compatible with the preloaded multiSert™ or Vivinex™ iSert® injector systems, allowing for versatile single-handed or two-handed injection methods. The recommended incision size is 2.20 mm, facilitating a minimally invasive procedure.

Clinical Benefits

• Astigmatism Correction: The lens is engineered to significantly reduce postoperative refractive astigmatism, maintaining long-term correction and visual acuity.
• Glistening-Free Material: Laboratory testing confirms the glistening-free quality, ensuring consistent visual performance.

Indications

The HOYA Vivinex™ Toric IOL is intended for use by healthcare professionals in cataract surgery, providing a reliable solution for patients with corneal astigmatism. For comprehensive usage instructions, healthcare providers should refer to the official Instructions For Use.
