Description

The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed for patients undergoing cataract surgery with a need for astigmatism correction. This advanced lens offers healthcare professionals a reliable solution to enhance visual outcomes through its precise engineering and innovative features.

Optic Design

• Biconvex Structure: The lens features a biconvex optic with a square, thin, and textured edge.
• Aspheric Surface: The anterior aspheric surface partially compensates for corneal spherical aberration, improving tolerance to coma.
• Toric Surface: The posterior toric surface aids in astigmatism correction, with axis orientation marks for precise alignment.

Material and Clarity

Crafted from glistening-free hydrophobic acrylic, the lens includes integrated UV and blue light filters. The active oxygen processing enhances clarity and biocompatibility, while the smooth optic surface ensures superior visual quality.

Haptic Design

The textured-rough haptic surface, made from the same acrylic material, provides enhanced stability within the eye. The optic diameter measures 6.00 mm, with an overall length of 13.00 mm.

Power Specifications

• 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 correction.

Optical Constants

The lens offers optimized constants for various calculation formulas, including Haigis, Hoffer Q, Holladay 1, and SRK/T, ensuring accurate power prediction and alignment.

Injector System

The preloaded Vivinex™ iSert® or multiSert™ system facilitates consistent and predictable IOL delivery. With a front injector tip diameter of 1.70 mm, it recommends an incision size of 2.20 mm. The system supports single-handed push and two-handed screw injection for versatile handling.

Clinical Performance

The lens demonstrates exceptional rotational stability, with a median rotation of 1.1° up to six months post-surgery. Its design reduces posterior capsule opacification, leading to lower Nd:YAG capsulotomy rates compared to other IOLs.

Additional Features

• Proprietary Aspheric Optic Design: Enhances image quality and reduces visual disturbances.
• Consistent Delivery: The injector system components, including the tip, slider, rod, and knob, ensure outstanding delivery consistency.

The HOYA TORIC IOL VIVINEX ISERT stands out for its advanced optical performance and reliable delivery, making it a valuable choice for achieving optimal visual outcomes in cataract surgery patients with astigmatism.
