Description

The HOYA Vivinex™ Toric IOL (Model XY1A-SP) is a specialized intraocular lens designed for use in cataract surgery, offering advanced solutions for patients with astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens features both UV and blue light filters, ensuring long-term clarity and protection.

Optic and Haptic Design

• Optic Design: The lens boasts a biconvex optic with a square, thin, and textured edge. Its anterior aspheric and posterior toric designs are tailored to enhance visual performance.
• Haptic Design: The textured-rough haptic surface provides enhanced stability, crucial for maintaining the lens position within the eye.

Surface Treatment

Active oxygen processing results in a smooth surface, while the square optic edge design helps reduce posterior capsule opacification (PCO), contributing to clearer vision post-surgery.

Dimensions and Power Range

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

The lens offers a spherical power range from +10.00 to +30.00 diopters in 0.50 D increments. Cylinder power at the IOL plane ranges from 1.00 to 6.00 D, accommodating various levels of astigmatism correction.

A-Constant and Optimized Constants

The nominal A-constant is 118.9, with optimized constants provided for precise surgical outcomes across different calculation formulas.

Injector System

The lens is compatible with the preloaded multiSert™ or Vivinex™ iSert® injector systems, featuring a front injector tip outer diameter of 1.70 mm. The recommended incision size is 2.20 mm, allowing for versatile injection methods, including single-handed push or two-handed screw techniques.

Clinical Performance

The Vivinex™ Toric IOL demonstrates outstanding rotational stability, with a median rotation of 1.1° and 100% of lenses showing ≤5° rotation up to six months post-operation. Its proprietary aspheric optic design partially compensates for corneal spherical aberration, enhancing visual clarity and reducing the impact of coma.

Intended Use

This lens is intended for healthcare professionals to correct astigmatism during cataract surgery. Its design and material properties are supported by laboratory and clinical data, underscoring its clarity and stability.
