Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a specialized medical device designed to enhance visual outcomes for patients undergoing cataract surgery who also have pre-existing corneal astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional clarity and integrates both UV and blue light filters for comprehensive eye protection.

Advanced Optical Design

• Biconvex, Single-Piece Structure: Features an aspheric anterior surface and a toric posterior surface to effectively correct astigmatism and partially compensate for corneal spherical aberration.
• Precise Alignment: Axis orientation marks on the posterior surface ensure accurate alignment during implantation.

Dimensions and Power

• Optic Diameter: Typically 6.00 mm.
• Overall Length: Ranges from 12.5 mm to 13.00 mm depending on the model.
• Spherical Power Range: From +10.00 D to +30.00 D, with increments of 0.50 D.
• Toric Power Range: From 1.00 D to 6.00 D, tailored to individual patient needs.

Haptic Design for Stability

The lens features a textured haptic surface available in C-loop or anchor-wing designs, enhancing rotational stability. Clinical studies demonstrate remarkable rotational stability, with over 96% of lenses showing ≤5° rotation up to six months post-surgery.

Clinical Performance

• Reduced Posterior Capsule Opacification (PCO): Achieved through active oxygen processing and a square edge design, leading to lower PCO rates and reduced need for Nd:YAG capsulotomy compared to other IOLs.
• Proprietary Aspheric Design: Improves image quality and reduces visual aberrations such as decentration and coma.

Preloaded Injector Systems

The Vivinex™ Toric IOL is compatible with multiSert™ or Vivinex™ iSert® preloaded injector systems, facilitating a seamless implantation process. The injector system features a front tip diameter of 1.70 mm, suitable for a recommended incision size of 2.20 mm, ensuring precise and controlled lens insertion.

Calculation Constants

• Nominal A-Constant: 118.9
• Optimized Constants: Available for various formulas including Haigis, Hoffer Q, Holladay 1, and SRK/T, aiding in accurate lens power calculation.

Intended Use

The HOYA Vivinex™ Toric IOL is intended for healthcare professionals aiming to provide patients with improved visual acuity and long-term stability post-cataract surgery. Its innovative design and material properties make it a reliable choice for achieving excellent clinical outcomes.
