Description

The HOYA TORIC IOL XY1AT3, also known as Vivinex™ Toric IOL, is a specialized intraocular lens designed for use in cataract surgery to correct astigmatism. Crafted from hydrophobic acrylic material, this lens offers a glistening-free experience and includes both UV and blue light filters, enhancing visual clarity and protection.

Optic Design

• Biconvex Shape: The lens features a biconvex shape with an aspheric anterior design and a toric posterior design.
• Sharp Optic Edge: Its square, thin, and textured optic edge is engineered to reduce posterior capsule opacification (PCO), contributing to long-term visual outcomes.

Surface Treatment

The lens undergoes active oxygen processing treatment, resulting in a smooth and regular surface. This advanced treatment helps maintain lens clarity and performance over time.

Haptic Design

The textured-rough haptic surface of the lens enhances stability within the eye, ensuring precise positioning. With an optic diameter of 6.00 mm and an overall length of 13.00 mm, the lens is designed for optimal fit and function.

Power Range

The spherical power ranges from +10.00 to +30.00 diopters in 0.50 D increments, while the cylinder power at the IOL plane ranges from 1.00 to 6.00 D. This extensive range allows for tailored correction to meet individual patient needs.

Injector System

The preloaded multiSert™ (iSert®) injector system facilitates seamless implantation, with a front injector tip outer diameter of 1.70 mm and a recommended incision size of 2.20 mm.

Clinical Performance

• Rotational Stability: The lens demonstrates outstanding rotational stability, with over 96% of lenses rotating ≤5° at follow-up visits.
• Aspheric Optic Design: This design partially compensates for corneal spherical aberration, enhancing visual quality.
• PCO Reduction: The active oxygen processing and square edge design significantly reduce PCO scores and Nd:YAG capsulotomy rates compared to other lenses.

Compatibility

The HOYA TORIC IOL XY1AT3 is compatible with the HOYA Toric Calculator and supports the Abulafia–Koch Regression formula for posterior corneal astigmatism. This compatibility aids healthcare professionals in achieving precise surgical outcomes.

Intended Use

Intended for use by healthcare professionals, this lens is a sophisticated tool in cataract surgery, offering reliable correction for astigmatism. Availability may vary by country, aligning with local medical regulations.
