Description
The HOYA Vivinex™ Toric IOL (Model XY1AT4) is a specialized intraocular lens designed to enhance visual outcomes for patients undergoing cataract surgery with astigmatism. Crafted from hydrophobic acrylic material, this lens offers exceptional clarity by being glistening-free and includes UV and blue light filtering properties.
Optic Design
- Biconvex Shape: Features a square, thin, and textured edge for optimal performance.
- Aspheric Anterior Surface: Enhances image quality by compensating for corneal spherical aberration.
- Toric Posterior Surface: Provides precise astigmatism correction.
Dimensions
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
Power Specifications
- Spherical Power Range: +10.00 to +30.00 D in 0.50 D increments.
- Cylinder Power at IOL Plane: 1.00 to 6.00 D, offering detailed increments for tailored correction.
Haptic Design
The lens includes a textured-rough haptic surface, ensuring enhanced stability within the eye. This design contributes to the lens's outstanding rotational stability, with clinical studies showing minimal rotation post-implantation.
Advanced Features
- Active Oxygen Processing: Applied to the posterior surface to reduce posterior capsule opacification (PCO).
- Square Edge Design: Further minimizes PCO, leading to lower Nd:YAG capsulotomy rates compared to other IOLs.
Injector System
The lens comes preloaded with the multiSert™ or Vivinex™ iSert® injector system, facilitating a smooth surgical procedure. The injector system is designed for a recommended incision size of 2.20 mm, promoting ease of use and precision.
Clinical Benefits
- Rotational Stability: Median rotation of 1.1º with over 96% of lenses rotating ≤5° post-implantation.
- Image Quality: Enhanced by the aspheric optic design.
Compatibility
Compatible with the HOYA Toric Calculator, this lens allows for precise cylinder power calculation, ensuring tailored visual correction for each patient.
Intended Use
The HOYA Vivinex™ Toric IOL XY1AT4 is intended for use by healthcare professionals in cataract surgeries for patients with astigmatism. Its availability may vary by country, aligning with local medical regulations.
This lens represents a sophisticated solution for achieving superior visual outcomes, combining advanced material technology with innovative design features.
