Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL) is expertly designed to address the needs of patients undergoing cataract surgery with pre-existing corneal astigmatism. This advanced lens replaces the natural lens, providing clear vision and reducing astigmatism, thereby enhancing overall visual outcomes.
Innovative Material
Crafted from glistening-free hydrophobic acrylic, the Vivinex™ material incorporates integrated UV and blue light filters, offering protection and clarity. This ensures long-term visual quality without the common disturbances associated with other lens materials.
Optic Design
The lens features a biconvex optic with a unique anterior aspheric design, which partially compensates for corneal spherical aberration and improves tolerance to coma. The posterior toric design is specifically tailored for effective astigmatism correction. The optic's smooth surface, achieved through active oxygen processing, and its square, thin, textured edge contribute to reducing posterior capsule opacification (PCO).
Haptic Design
The textured-rough haptic surface enhances lens stability and minimizes adhesion, ensuring precise positioning within the eye. The optic diameter measures 6.00 mm, with an overall length of 13.00 mm, providing a compact and effective solution for a wide range of patients.
Power Ranges
The lens offers a broad range of spherical powers from +10.00 D to +30.00 D, and cylinder powers at the IOL plane from 1.00 D to 6.00 D, allowing for tailored correction. The Gemetric Plus Toric model further enhances visual performance with a trifocal design, providing add powers for near and intermediate vision.
Injector System
The preloaded multiSert™ or iSert® injector system facilitates precise and flexible implantation, accommodating various surgical techniques. The system's design allows for a recommended incision size of 2.20 mm, promoting minimally invasive procedures.
Clinical Performance
Rotational Stability
The Vivinex™ Toric IOL demonstrates exceptional rotational stability, with over 96% of lenses maintaining ≤5° of rotation post-implantation. This stability is crucial for consistent visual outcomes, particularly in eyes with high axial lengths.
Visual Performance
The Gemetric Plus Toric model excels in providing clear vision across all distances and lighting conditions, making it an ideal choice for patients seeking comprehensive visual correction.
Professional Use
Intended for use by healthcare professionals, the HOYA Vivinex™ Toric IOL requires special diagnostic measurements for optimal alignment and performance. Availability may vary by region, and healthcare providers should refer to local regulatory guidelines and the Instructions For Use for detailed indications and contraindications.
