Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL), Model XY1A-SP, is a specialized lens designed for use in cataract surgery, offering precise correction for patients with pre-existing corneal astigmatism. Manufactured by Hoya Surgical Optics, this lens is crafted from glistening-free hydrophobic acrylic, ensuring long-term optical clarity.
Key Features
- UV and Blue Light Filtering: Provides protection for the eye, enhancing visual comfort.
- Advanced Optic Design: Features a biconvex shape with a square, thin, textured edge. The anterior aspheric surface enhances image quality by partially compensating for corneal spherical aberration.
- Toric Surface: The posterior toric surface aids in precise astigmatism correction.
Haptic Design
- Textured-Rough Surface: Ensures enhanced stability within the eye.
- C-Loop Configuration: Contributes to the secure positioning of the lens.
Dimensions
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
Power Range
- Spherical Power: +10.00 to +30.00 diopters (D) in 0.50 D increments.
- Cylinder Power: Ranges from 1.00 to 6.00 D at the IOL plane, with specific increments for precise customization.
Rotational Stability
The lens demonstrates exceptional rotational stability, with over 96% of lenses rotating ≤5° post-implantation. This stability is crucial for consistent astigmatism correction.
Surface Processing
- Active Oxygen Processing: Applied to the posterior surface for a smooth, regular optic surface.
- Square Edge Design: Reduces posterior capsule opacification (PCO), maintaining lens clarity.
Injector System
The lens comes with a preloaded multiSert™ injector system, allowing for versatile and precise implantation through a recommended incision size of 2.20 mm.
Clinical Benefits
- High Rotational Stability: Ensures effective astigmatism correction.
- Proprietary Aspheric Optic Design: Enhances image quality.
- Reduced PCO Rates: Compared to some other IOLs, leading to fewer Nd:YAG capsulotomies.
Indications
The HOYA Vivinex™ Toric IOL is intended for healthcare professionals performing cataract surgery in patients with corneal astigmatism. It is primarily a monofocal toric lens, with some models offering additional capabilities.
