Description

The HOYA Vivinex™ Toric IOL (Model XY1AT2) is an advanced intraocular lens designed to address astigmatism correction during cataract or refractive lens exchange surgeries. Crafted by HOYA Surgical Optics, this lens is made from glistening-free hydrophobic acrylic, ensuring long-term clarity and visual performance.

Key Features

• UV and Blue Light Filter: Integrated to protect the eye from harmful light exposure.
• Aspheric Optic Design: Includes a biconvex shape with an anterior aspheric surface and a posterior toric surface for enhanced visual outcomes.
• Optic Edge Design: Features a square, thin, textured edge to minimize posterior capsule opacification (PCO).
• Axis Orientation Markers: Located on the posterior surface for precise alignment.

Haptic Design

The lens includes a textured-rough haptic surface, promoting stability within the eye. Active oxygen processing and a square edge design further reduce PCO, enhancing post-surgical clarity.

Dimensions and Power Range

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm
• Spherical Power Range: +10.00 to +30.00 D in 0.50 D increments
• Cylinder Power at IOL Plane: 1.00 to 6.00 D (T2 to T9)

Rotational Stability

The lens demonstrates exceptional rotational stability, with over 96% of lenses rotating ≤5º at follow-up. This stability is supported by clinical studies, ensuring consistent visual outcomes.

Injector System

The preloaded multiSert™ or iSert® injector system offers versatility with single-handed push and two-handed screw injection options. It features an adjustable insert shield and a recommended incision size of 2.20 mm.

Clinical Performance

The proprietary aspheric optic design partially compensates for corneal spherical aberration, contributing to effective astigmatism correction. Clinical data highlights significantly lower PCO scores and Nd:YAG capsulotomy rates compared to other IOLs.

Visual Acuity Outcomes

• Postoperative Refractive Cylinder: Reduced to –0.14 ± 0.22 D (mean ± SD)
• Visual Acuity (logMAR, mean ± SD):
• Monocular UDVA (4 m): 0.11 ± 0.12
• Binocular UDVA (4 m): 0.05 ± 0.11
• Monocular CDVA (4 m): 0.05 ± 0.08
• Binocular CDVA (4 m): 0.02 ± 0.09

Additional Benefits

Designed for use in standard and duet procedures, the HOYA Vivinex™ Toric IOL maintains rotational stability and optical quality, even when used with supplementary IOLs. This makes it a versatile choice for achieving optimal visual outcomes in diverse surgical settings.
