Description
The HOYA Vivinex™ Toric IOL, available in models XY1A and XY1A-SP, is a specialized intraocular lens designed for use in cataract surgery to correct astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens features advanced optical and haptic designs to enhance visual outcomes and stability.
Optical Design
- Biconvex Shape: The lens incorporates a biconvex shape with a square, thin, and textured optic edge.
- Aspheric and Toric Design: The anterior surface is aspheric, while the posterior surface is toric, complete with axis orientation marks for precise alignment.
- UV and Blue Light Filtering: Integrated filters provide protection against UV and blue light.
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 Range: At the IOL plane, 1.00 to 6.00 D, with specific increments for precise correction.
Haptic Design
The lens features a textured-rough haptic surface, contributing to enhanced stability within the eye post-implantation.
Injector System
Preloaded with the Vivinex™ iSert® (multiSert™) system, the lens allows for a recommended incision size of 2.20 mm, facilitating consistent and easy delivery.
Clinical Performance
- Rotational Stability: Demonstrates exceptional stability with a median rotation of 1.1°, ensuring alignment remains within 5° for the majority of lenses.
- Optical Performance: The proprietary aspheric design compensates for corneal spherical aberration, enhancing image quality.
PCO Prevention
The lens is engineered to reduce posterior capsule opacification through active oxygen processing and a square posterior optic edge, maintaining clarity over time.
