Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL), Model XY1AT4, is expertly crafted to enhance visual outcomes for patients undergoing cataract surgery with astigmatism. This advanced lens is made from glistening-free hydrophobic acrylic, ensuring long-term clarity and durability.
Key Features
- Optic Design: The lens features a biconvex optic with an aspheric anterior surface and a toric posterior surface. This design contributes to improved rotational stability and reduced posterior capsule opacification (PCO).
- Light Filtration: Integrated UV and blue light filters provide additional protection for the eye.
- Edge Design: A sharp, square, and textured optic edge further minimizes PCO.
Dimensions and Power
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
- Spherical Power Range: +10.00 to +30.00 D in 0.50 D increments
- Cylinder Power (Toric): Model XY1AT4 (T4) offers 2.25 D at the IOL plane and 1.56 D at the corneal plane
Haptic Design
The textured-rough haptic surface enhances the lens's stability within the eye, ensuring precise positioning.
Injector System
Preloaded in the Vivinex™ iSert® or multiSert™ injector, the lens allows for a recommended incision size of 2.20 mm, facilitating a smooth implantation process.
Clinical Performance
- Rotational Stability: Demonstrated median rotation of 1.1°, with over 96% of lenses rotating ≤5° up to six months post-surgery.
- Aspheric Optic Design: Partially compensates for corneal spherical aberration, enhancing image quality.
- PCO Reduction: Active oxygen processing and smooth, sharp edge design contribute to lower PCO and Nd:YAG capsulotomy rates.
Intended Use
Designed for healthcare professionals, the HOYA Vivinex™ Toric IOL XY1AT4 is intended for implantation during cataract surgery in patients requiring astigmatism correction. Its availability may vary by country, aligning with specific healthcare needs.
This lens represents a significant advancement in intraocular lens technology, offering clarity, stability, and precision for optimal visual rehabilitation.
