Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL) is expertly crafted to address astigmatism correction during cataract surgery. This advanced lens is constructed from glistening-free hydrophobic acrylic, ensuring exceptional clarity and long-term performance.
Key Features
- Aspheric and Toric Optic Design: Enhances visual outcomes by partially compensating for corneal spherical aberration and increasing tolerance to coma.
- High Rotational Stability: Engineered to maintain precise positioning, reducing the likelihood of visual disturbances post-surgery.
- Reduced Posterior Capsule Opacification (PCO): Features such as a smooth surface and square optic edge significantly lower PCO incidence, as supported by clinical trials.
Dimensions and Power Range
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
- Spherical Power Range: +10.00 to +30.00 D
- Cylinder Power Range: 1.00 to 6.00 D at the IOL plane
Haptic Design
The lens includes a textured-rough haptic surface with axis orientation marks, enhancing stability and alignment within the eye.
Light Filtration
Equipped with UV and blue light filters, the lens provides additional protection for ocular health.
Injector System
Available with the preloaded multiSert™ or iSert® injector systems, allowing for versatile and precise implantation through a recommended incision size of 2.20 mm.
Optical Constants
- Nominal A-constant: 118.9
- Optimized Constants: Tailored for various calculation methods, ensuring accurate lens power prediction.
Clinical Performance
Demonstrates proven rotational stability with a median rotation of 1.1°, and maintains clarity with lower PCO scores compared to other lenses. The HOYA Toric Calculator supports precise cylinder power calculation, enhancing surgical outcomes.
Indications
Intended for patients undergoing cataract or refractive lens extraction surgery with corneal astigmatism. Not recommended for individuals with specific ocular conditions such as severe dry eye or irregular astigmatism.
This lens exemplifies HOYA's commitment to innovative ophthalmic solutions, providing consistent and predictable visual results for patients worldwide.
