Description
The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed for patients undergoing cataract surgery with astigmatism. This lens offers advanced features to enhance visual outcomes and surgical precision.
Optic Design
- Biconvex Structure: The lens features a biconvex optic with a square, thin, and textured edge.
- Aspheric and Toric Surfaces: An anterior aspheric surface and a posterior toric surface help in minimizing posterior capsule opacification (PCO).
- Proprietary Design: The aspheric optic design compensates for corneal spherical aberration and improves tolerance to coma, enhancing visual clarity.
Material and Filters
- Glistening-Free Acrylic: Made from Vivinex™ hydrophobic acrylic, ensuring long-term clarity.
- UV and Blue Light Filters: Integrated filters provide additional protection for the eye.
Haptic Design
- Textured Surface: The haptic design features a textured-rough surface for enhanced rotational stability.
- Material Consistency: Made from the same material as the optic, ensuring compatibility and performance.
Dimensions
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
Power Specifications
- Spherical Power Range: +10.00 to +30.00 diopters (D) in 0.50 D increments.
- Cylinder Power Range: At the IOL plane, 1.00 to 6.00 D; at the corneal plane, 0.69 to 4.17 D.
Optical Constants
- A-Constant: Nominal value of 118.9.
- Optimized Constants: Provided for various calculation formulas including Haigis, Hoffer Q, Holladay 1, and SRK/T.
Injector System
- Preloaded System: Available with Vivinex™ iSert® or multiSert™ injector systems.
- Incision Size: Recommended size of 2.20 mm, supporting single- or two-handed injection.
Rotational Stability
- Minimal Rotation: Median rotation of 1.1° with 100% of lenses having ≤5° rotation up to 6 months post-surgery.
- High Stability: Over 96% of lenses maintain stability, even in eyes with high axial lengths.
Surface Treatment
- Active Oxygen Processing: Provides a smooth surface and square optic edge to reduce PCO.
Clinical Performance
- Lower PCO Rates: Demonstrates lower PCO and Nd:YAG capsulotomy rates compared to other IOLs.
- High Clarity and Biocompatibility: Ensures long-term performance and patient satisfaction.
Additional Features
- Axis Orientation Marks: Located on the posterior surface for precise alignment during surgery.
- Professional Use: Specifically designed for healthcare professionals treating cataract surgery patients with astigmatism.
