Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a specialized lens designed to correct astigmatism during cataract surgery. Crafted from hydrophobic acrylic, this lens offers glistening-free clarity, ensuring long-term visual quality. Its design includes a UV and blue light filter, providing additional protection for the eye.
Optic Design
- Biconvex, Single-Piece Lens: Features an anterior aspheric surface to partially compensate for corneal spherical aberration, enhancing visual outcomes.
- Posterior Toric Surface: Aids in precise astigmatism correction.
- Textured Optic Edge: The square, thin edge design helps reduce posterior capsule opacification.
- Axis Orientation Marks: Located on the posterior for accurate alignment.
Haptic Design
- C-Loop Design: Ensures stable positioning within the eye.
- Textured-Rough Surface: Enhances stability, reducing lens movement post-implantation.
Dimensions
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
Power Range
- Spherical Power: +10.00 D to +30.00 D in 0.50 D increments.
- Cylinder Power (IOL Plane): 1.00 D to 6.00 D, tailored for precise astigmatism correction.
Injector System
The lens is compatible with the preloaded multiSert™ or Vivinex™ iSert® injector system, facilitating a recommended incision size of 2.20 mm for seamless implantation.
Clinical Performance
- Rotational Stability: Over 96% of lenses rotate ≤5° post-implantation, ensuring consistent visual outcomes.
- Reduced Posterior Capsule Opacification: Achieved through active oxygen processing and a smooth lens surface.
Intended Use
Designed for healthcare professionals, the Vivinex™ Toric IOL is intended for adult patients undergoing cataract surgery with pre-existing corneal astigmatism. Its advanced design aims to significantly reduce postoperative refractive astigmatism, enhancing overall visual clarity.
Additional Notes
Clinical studies highlight lower posterior capsule opacification scores and reduced Nd:YAG capsulotomy rates compared to other IOLs, underscoring its effectiveness and reliability. The lens specifications may evolve with ongoing development, maintaining its position at the forefront of intraocular lens technology.
