Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a specialized lens designed for patients undergoing cataract surgery who also require astigmatism correction. Crafted from hydrophobic acrylic, this lens offers exceptional clarity with its glistening-free material, ensuring optimal visual outcomes.
Advanced Optic Design
- Biconvex, Single-Piece Lens: Features an anterior aspheric surface to partially compensate for corneal spherical aberration, enhancing visual quality.
- Posterior Toric Surface: Specifically tailored for effective astigmatism correction.
- Square, Thin, Textured Optic Edge: Provides a smooth, regular optic surface with axis orientation marks for precise alignment.
Material and Filtering
- UV and Blue Light Filter: Protects the eye while maintaining clarity.
- Glistening-Free Vivinex™ Material: Ensures long-term transparency and performance.
Haptic Design
- C-Loop Haptic Design: Includes a textured-rough surface for enhanced lens stability post-implantation.
- Dimensions: Optic diameter of 6.00 mm and an overall length ranging from 12.5 mm to 13.00 mm.
Power Specifications
- Spherical Power: Ranges from +10.00 D to +30.00 D in 0.50 D increments.
- Cylinder Power: IOL plane power from 1.00 D to 6.00 D, with specific increments for precise correction.
Injector System
The lens comes with a preloaded multiSert™ or iSert® injector system, facilitating a recommended incision size of 2.20 mm for seamless implantation.
Clinical Performance
- High Rotational Stability: Over 96% of lenses rotate ≤5° post-implantation, ensuring consistent visual correction.
- Low Incidence of Posterior Capsule Opacification (PCO): Achieved through active oxygen processing and a smooth lens surface.
Special Features
Select models offer trifocal capabilities, providing clear vision across near, intermediate, and distance ranges, with a diffractive zone for multifocality.
Intended Use
Designed for healthcare professionals, the HOYA Vivinex™ Toric IOL aims to deliver stable, high-quality vision correction, minimizing posterior capsule opacification for patients with cataracts and corneal astigmatism.
