Description

The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed for cataract surgery, offering precise astigmatism correction. Crafted from glistening-free hydrophobic acrylic, it features both UV and blue light filters, ensuring optimal visual clarity and protection.

Optic and Haptic Design

• Optic Design: The lens boasts a biconvex shape with an aspheric anterior surface and a toric posterior surface. Its square, thin, and textured optic edge enhances performance.
• Haptic Design: The textured-rough haptic surface provides enhanced stability, crucial for maintaining lens position post-surgery.

Dimensions and Power Range

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

Rotational Stability

The lens demonstrates exceptional rotational stability, with over 96% of lenses rotating ≤5° post-implantation. This stability is maintained even in eyes with high axial lengths, ensuring consistent visual outcomes.

Optical Constants

For accurate IOL power calculation, the lens provides specific optical constants, including:

• Nominal A-constant: 118.9
• Haigis, Hoffer Q, Holladay 1, and SRK/T parameters

Injector System

The preloaded Vivinex™ iSert® or multiSert™ system allows for versatile injection methods, accommodating both single-handed and two-handed techniques. The recommended incision size is 2.20 mm, facilitated by the front injector tip's outer diameter of 1.70 mm.

Surface and Edge Technology

Active oxygen processing ensures a smooth IOL surface, while the square optic edge design reduces posterior capsule opacification (PCO). These features contribute to the lens's long-term clarity and performance.

Clinical Performance

The lens's proprietary aspheric optic design compensates for corneal spherical aberration, enhancing visual quality. It also shows reduced PCO compared to other IOLs, leading to lower Nd:YAG capsulotomy rates.

Professional Use

Designed for healthcare professionals, the HOYA TORIC IOL VIVINEX ISERT offers outstanding delivery consistency and predictability in cataract surgeries. Specifications may vary due to ongoing technical developments, and availability can differ by region. For comprehensive usage guidelines, refer to the Instructions For Use.
