Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL), Model XY1A-SP, is a specialized lens designed for patients undergoing cataract surgery who also require correction for corneal astigmatism. This advanced lens offers several key features that enhance visual outcomes and surgical performance.
Key Features
- Material and Design:
- Made from glistening-free hydrophobic acrylic, the lens provides exceptional clarity and durability.
-
Equipped with UV and blue light filters to protect the eye from harmful light exposure.
-
Optic Design:
- The biconvex, single-piece optic includes an anterior aspheric surface to partially compensate for corneal spherical aberration, improving visual quality.
- The posterior toric surface is specifically engineered for effective astigmatism correction.
-
Features such as a square, thin optic edge and axis orientation marks aid in precise alignment and reduce posterior capsule opacification (PCO).
-
Haptic Design:
- The C-loop haptic with a textured surface enhances the lens's rotational stability within the eye.
Dimensions
- Optic diameter: 6.00 mm
- Overall length: 13.00 mm
- Injector tip outer diameter: 1.70 mm
- Recommended incision size: 2.20 mm
Power Ranges
- Spherical power ranges from +10.00 D to +30.00 D in 0.50 D increments.
- Cylinder power at the IOL plane ranges from 1.00 D to 6.00 D, providing tailored correction for various levels of astigmatism.
Injector System
The preloaded multiSert™ injector system allows for versatile and precise lens delivery, offering both single-handed and two-handed injection options. This system enhances surgical efficiency and accuracy.
Clinical Performance
- Rotational Stability:
-
Demonstrates excellent stability with over 96% of lenses rotating ≤5° post-implantation.
-
PCO Resistance:
- The lens's design and material significantly reduce PCO, leading to lower Nd:YAG capsulotomy rates compared to other lenses.
Intended Use
The HOYA Vivinex™ Toric IOL is intended for healthcare professionals to implant in patients with cataracts and corneal astigmatism, ensuring improved visual outcomes and long-term satisfaction. Its innovative features make it a reliable choice for achieving clear, stable vision post-surgery.
