Description

The HOYA TORIC IOL VIVINEX ISERT is an advanced intraocular lens designed specifically for healthcare professionals performing cataract surgery on patients with pre-existing corneal astigmatism. This lens offers precise vision correction through its sophisticated optic and haptic design, ensuring optimal outcomes for patients.

Optic Design

• Biconvex Aspheric Optic: Features an anterior aspheric surface and a posterior toric surface, enhancing visual clarity.
• Integrated Filters: Equipped with UV and blue light filters to protect the eye.
• Textured Edge: The square, thin, textured optic edge includes axis orientation marks for precise alignment.

Material and Stability

Crafted from glistening-free hydrophobic acrylic, the lens provides exceptional clarity and long-term performance. The textured-rough haptic surface, made from the same material, enhances stability within the eye, reducing the risk of lens movement 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: Offers a range at the IOL plane from 1.00 to 6.00 D, tailored for precise astigmatism correction.

Injector System

The lens comes preloaded in the Vivinex™ iSert® or multiSert™ injector system, facilitating a smooth implantation process. The injector system is designed for a recommended incision size of 2.20 mm and offers versatile handling options to suit surgical preferences.

Rotational Stability

With a median rotation of just 1.1°, the lens demonstrates outstanding rotational stability. Clinical data shows that 100% of lenses exhibit ≤5° rotation at various postoperative intervals, ensuring consistent visual outcomes.

Surface Treatment and Clinical Benefits

The lens undergoes active oxygen processing treatment, enhancing surface smoothness and biocompatibility. Its square optic edge design significantly reduces posterior capsule opacification (PCO), leading to lower Nd:YAG capsulotomy rates compared to other IOLs.

Advanced Optic Design

The proprietary aspheric optic design compensates for corneal spherical aberration and improves tolerance to coma, contributing to superior visual performance. Supported by laboratory and clinical data, the lens offers clarity, stability, and biocompatibility.

Calculation Tools

The HOYA Toric Calculator, including the Abulafia-Koch Regression formula, supports precise cylinder power calculation, accounting for posterior corneal astigmatism. This ensures accurate power selection tailored to each patient's needs.

This intraocular lens represents a comprehensive solution for achieving high-quality visual outcomes in cataract surgery, backed by innovative design and robust clinical evidence.
