Description
The HOYA TORIC IOL VIVINEX ISERT is an advanced intraocular lens designed to enhance visual outcomes for patients undergoing cataract surgery with astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens incorporates a UV and blue light filter to protect the eye while providing exceptional clarity.
Optic and Haptic Design
The lens features a biconvex optic with an aspheric anterior surface and a toric posterior surface, engineered to improve image quality and reduce visual aberrations. Its square, thin, and textured optic edge, along with a smooth surface, helps in minimizing posterior capsule opacification (PCO). The textured-rough haptic surface enhances the lens's rotational stability, ensuring precise alignment within the eye.
Preloaded Injector System
Available with the Vivinex™ iSert® and multiSert™ preloaded injectors, the system offers both single-handed push and two-handed screw injection options. This design allows for consistent and predictable lens delivery, with an adjustable insert shield for precise insertion depth.
Rotational Stability
The HOYA TORIC IOL VIVINEX ISERT demonstrates remarkable rotational stability, with clinical data showing a median rotation of just 1.1° and 100% of lenses maintaining ≤5° rotation up to six months post-surgery. This stability is crucial for patients with high axial lengths, ensuring long-term visual performance.
Technical Specifications
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
- Power Range: +10.00 to +30.00 diopters in 0.50 D increments
- Cylinder Power (IOL Plane): 1.00 to 6.00 D
The lens is designed to partially compensate for corneal spherical aberration, enhancing visual clarity and tolerance to optical imperfections such as coma.
Clinical Benefits
Clinical studies highlight the lens's low incidence of PCO and consistent clarity, making it a reliable choice for ophthalmic surgeons. The recommended incision size of 2.20 mm and the injector tip diameter of 1.70 mm facilitate a minimally invasive surgical approach.
Intended Use
This lens is intended for use by healthcare professionals, with detailed instructions and specifications available in the official Instructions For Use. As with all medical devices, ongoing technical development may lead to design and specification changes.
The HOYA TORIC IOL VIVINEX ISERT represents a significant advancement in intraocular lens technology, offering tailored solutions for patients seeking improved visual outcomes after cataract surgery.
