Description

The HOYA Vivinex™ Toric IOL XY1AT9 is a specialized intraocular lens designed to enhance visual outcomes for patients undergoing cataract surgery with astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional clarity and durability, incorporating both UV and blue light filters for comprehensive eye protection.

Advanced Optic and Haptic Design

• Optic Design: The lens features a biconvex shape with an aspheric anterior and toric posterior design. Its square, thin, and textured optic edge is engineered to minimize visual disturbances and improve lens positioning.
• Haptic Design: The textured-rough haptic surface ensures enhanced stability within the eye, maintaining precise alignment.

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 Range: At the IOL plane from 1.00 to 6.00 D, tailored for effective astigmatism correction.

Exceptional Rotational Stability

Clinical data highlights the lens's outstanding rotational stability, with over 96% of lenses rotating ≤5° up to six months post-surgery. This stability is crucial for consistent visual performance and is supported by active oxygen processing and a smooth IOL surface.

Reduction of Posterior Capsule Opacification

The square optic edge design significantly reduces posterior capsule opacification (PCO), enhancing long-term visual clarity. The aspheric optic design also compensates for corneal spherical aberration, improving visual quality and tolerance to optical imperfections.

Preloaded Injector System

The Vivinex™ Toric IOL XY1AT9 comes with a preloaded multiSert™ or Vivinex™ iSert® injector system. This system features a front injector tip with an outer diameter of 1.70 mm, suitable for a recommended incision size of 2.20 mm. The adjustable insert shield allows for precise insertion, offering both single-handed and two-handed injection options.

Axis Orientation and Calculation Support

Axis orientation marks on the posterior surface aid in accurate alignment during surgery. The lens's power calculation is supported by the HOYA Toric Calculator, utilizing the Abulafia–Koch Regression formula for precise outcomes. Optimized calculation constants further enhance accuracy across various formulas, including Haigis, Hoffer Q, Holladay 1, and SRK/T.

Proven Clinical Performance

The HOYA Vivinex™ Toric IOL XY1AT9 demonstrates significantly lower PCO rates compared to other IOLs, backed by laboratory and clinical studies. Its biocompatibility, clarity, and stability make it a reliable choice for ophthalmic surgeons aiming to achieve superior visual results for their patients.
