Description

The HOYA TORIC IOL VIVINEX ISERT is an advanced intraocular lens designed specifically for patients undergoing cataract surgery with astigmatism. This lens offers a range of features that enhance visual clarity and stability, making it a reliable choice for ophthalmic professionals.

Key Features

• Material: The lens is crafted from glistening-free hydrophobic acrylic, providing exceptional clarity. It includes integrated UV and blue light filters to protect the eye.

• Optic Design: The biconvex optic features an aspheric anterior surface and a toric posterior surface. Its square, thin, and textured optic edge is designed to reduce posterior capsule opacification (PCO).

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

Dimensions

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm

Power Specifications

• Spherical Power Range: +10.00 to +30.00 D in 0.50 D increments
• Cylinder Power (IOL Plane): 1.00 to 6.00 D (T2 to T9)

Rotational Stability

The lens demonstrates excellent rotational stability, with a median rotation of 1.1° and 100% of lenses showing ≤5° rotation up to six months post-implantation.

Surface Treatment

Active oxygen processing is used to create a smooth surface, further reducing PCO. The lens also features axis orientation marks on the posterior surface for precise alignment.

Delivery System

The lens comes preloaded in the Vivinex™ iSert® or multiSert™ injector system, allowing for a recommended incision size of 2.20 mm. The injector system offers both single-handed and two-handed injection options, providing flexibility during surgery.

Optimized Constants

These constants are crucial for accurate IOL power calculations, including:

• Nominal A-constant: 118.9
• Haigis: a0 = 0.8733, a1 = 0.2093, a2 = 0.2277
• Hoffer Q: pACD = 5.693

Clinical Performance

Clinical studies highlight the lens's rotational stability, with over 96% of lenses rotating ≤5° post-implantation. The proprietary aspheric optic design compensates for corneal spherical aberration, enhancing visual outcomes.

Conclusion

The HOYA TORIC IOL VIVINEX ISERT is engineered to provide superior visual outcomes for cataract patients with astigmatism, offering advanced features that ensure clarity, stability, and ease of implantation.
