Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL) is expertly crafted to address the needs of patients undergoing cataract surgery who also require correction for corneal astigmatism. Designed with healthcare professionals in mind, this lens offers a range of features that enhance visual outcomes and surgical precision.
Material and Design
- Hydrophobic Acrylic: The lens is made from a glistening-free hydrophobic acrylic material, ensuring long-term optical clarity.
- UV and Blue Light Filter: Provides protection against harmful light exposure.
- Aspheric Optic Design: Includes a biconvex, single-piece lens with an anterior aspheric surface to partially compensate for corneal spherical aberration, enhancing visual quality.
Surface and Haptic Features
- Posterior Toric Surface: Designed for precise astigmatism correction.
- Textured Optic Edge: Features a square, thin, and textured optic edge to minimize posterior capsule opacification (PCO).
- C-Loop Haptic Design: Ensures stable lens positioning with a textured-rough surface.
Dimensions and Power Range
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm (some models may be 12.5 mm)
- Spherical Power Range: +10.00 D to +30.00 D
- Cylinder Power Range: 1.00 D to 6.00 D
Injector System
The lens comes with a preloaded multiSert™ or Vivinex™ iSert® injector system, facilitating a recommended incision size of 2.20 mm for seamless implantation.
Performance Highlights
- Rotational Stability: Over 96% of lenses exhibit rotation of ≤5° post-implantation, ensuring consistent visual outcomes.
- PCO Prevention: Advanced surface treatments and design features significantly reduce PCO incidence, as evidenced by lower clinical scores and Nd:YAG capsulotomy rates.
Clinical Benefits
The HOYA Vivinex™ Toric IOL is a reliable choice for achieving clear, stable vision post-surgery, tailored for patients with cataracts and corneal astigmatism. Its innovative design and material properties contribute to superior performance and patient satisfaction.
