Description

The HOYA Vivinex™ Toric IOL is an advanced intraocular lens specifically designed to address astigmatism during cataract surgery. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional clarity and durability. Its aspheric, monofocal design ensures precise vision correction, replacing the eye's natural lens to reduce distortion and enhance visual outcomes.

Key Features

• Optic Design: The lens features a biconvex optic with a square, thin, and textured edge. Its anterior aspheric surface and posterior toric surface are engineered to improve visual clarity and reduce aberrations.

• Material Benefits: Integrated with UV and blue light filters, the lens material protects the eye while maintaining transparency. The unique surface treatment with active oxygen processing provides a smooth finish, minimizing posterior capsule opacification (PCO).

• Haptic Design: The textured-rough haptic surface enhances lens stability within the eye, crucial for maintaining proper alignment and rotational stability.

Dimensions and Power

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm
• Spherical Power Range: +10.00 D to +30.00 D in 0.50 D increments
• Cylinder Power: Ranges from 1.00 D to 6.00 D at the IOL plane, with specific increments for precise astigmatism correction.

Rotational Stability

The HOYA Vivinex™ Toric IOL demonstrates outstanding rotational stability, with a median rotation between 1.1° and 1.54°. Clinical results show that over 96% of lenses remain within 5° of rotation post-implantation, ensuring consistent visual performance.

Clinical Performance

Clinical studies highlight the lens's low PCO rates and reduced Nd:YAG capsulotomy incidence compared to other IOLs. These attributes contribute to long-term visual clarity and patient satisfaction.

Optical Calculation Constants

• Nominal A-constant: 118.9
• Haigis, Hoffer Q, Holladay 1, and SRK/T constants are provided for precise optical calculations, aiding surgeons in achieving optimal refractive outcomes.

Injector System

The lens is preloaded in the multiSert™ or iSert® injector system, allowing for a recommended incision size of 2.20 mm. This system supports both single-handed and two-handed injection techniques, offering flexibility and precision during implantation.

Intended Use

The HOYA Vivinex™ Toric IOL is intended for patients undergoing cataract surgery who require astigmatism correction. Its monofocal nature provides optimal vision at a specific distance, typically enhancing distance vision. Proper diagnostic measurements are essential for effective astigmatism correction.

Conclusion

With its innovative design and proven clinical performance, the HOYA Vivinex™ Toric IOL stands out as a reliable choice for eye care professionals seeking to enhance surgical outcomes and patient satisfaction.
