Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a specialized medical device designed for patients undergoing cataract surgery who also require astigmatism correction. Crafted from hydrophobic acrylic, this lens offers exceptional clarity by being glistening-free and incorporates both UV and blue light filters for enhanced eye protection.

Advanced Optic Design

• Biconvex, Single-Piece Lens: The lens features a biconvex, single-piece design with a square, thin, and textured optic edge.
• Aspheric and Toric Surfaces: Its anterior aspheric surface compensates for corneal spherical aberration, while the posterior toric surface provides precise astigmatism correction.

Dimensions and Power Range

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm (with some models ranging from 12.5 to 13.00 mm)
• Spherical Power: Ranges from +10.00 D to +30.00 D
• Cylinder Power: At the IOL plane, ranges from 1.00 D to 6.00 D, with specific increments for precise correction

Haptic Design for Stability

The lens includes a textured-rough haptic surface with a C-loop design, ensuring stable positioning within the eye. Some models feature PMMA-modified haptics for additional stability.

Injector System

The preloaded multiSert™ or Vivinex™ iSert® injector system facilitates precise implantation, with a recommended incision size of 2.20 mm.

Clinical Performance

• Rotational Stability: Over 96% of lenses demonstrate minimal rotation (≤5°) post-implantation, ensuring consistent visual outcomes.
• Posterior Capsule Opacification (PCO) Prevention: The lens design significantly reduces PCO, maintaining long-term clarity.

Optical Quality

The aspheric optic design enhances image quality and tolerance to optical aberrations, providing patients with superior visual outcomes. The lens material maintains Grade 0 clarity, contributing to its outstanding optical performance.

Intended Use

This intraocular lens is intended for healthcare professionals to implant during cataract surgery in patients with pre-existing corneal astigmatism. Some models may offer additional features such as trifocal capabilities and diffractive zones for comprehensive vision correction across various distances.

Additional Features

Axis orientation marks are included for precise alignment, and the lens design may incorporate advanced features for specific models, such as the Vivinex Gemetric Plus Toric.

For comprehensive details on indications and contraindications, healthcare professionals should refer to the Instructions For Use provided with the lens.
