Description
The HOYA Vivinex™ Toric IOL (Model XY1AT3) is an advanced intraocular lens specifically designed for patients undergoing cataract surgery who also require astigmatism correction. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional optical clarity and long-term performance.
Key Features
-
Optic Design: The lens features a biconvex optic with an aspheric anterior surface and a toric posterior surface. This design helps in reducing spherical aberration, enhancing image quality for clearer vision.
-
Material Benefits: Equipped with UV and blue light filters, the lens provides additional protection for the eye, contributing to overall visual health.
-
Haptic Design: The textured surface of the haptic ensures enhanced stability within the eye, reducing the likelihood of lens rotation post-surgery. Both the optic and haptic are made from Vivinex™ hydrophobic acrylic, ensuring consistent performance.
Dimensions and Power
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
The lens is available in a power range from +10.00 to +30.00 diopters, with cylinder powers at the IOL plane ranging from 1.00 to 6.00 diopters. This range allows for precise customization to meet individual patient needs.
Clinical Performance
Clinical studies highlight the lens's outstanding rotational stability, with over 96% of lenses rotating 5 degrees or less. This stability is crucial for maintaining optimal visual outcomes. The aspheric optic design also aids in compensating for corneal spherical aberration, further improving image quality.
Advanced Features
The lens incorporates active oxygen processing and a smooth, square edge design to significantly reduce posterior capsule opacification (PCO). Clinical results demonstrate lower PCO scores and reduced Nd:YAG capsulotomy rates compared to other leading lenses, such as AcrySof® IQ.
Injector System
The preloaded multiSert™ or Vivinex™ iSert® injector system facilitates easy and precise implantation, recommended for an incision size of 2.20 mm. This system enhances surgical efficiency and outcomes.
Calculation Tools
Compatibility with the HOYA Toric Calculator and support for the Abulafia-Koch Regression formula allow for accurate estimation of posterior corneal astigmatism, aiding surgeons in achieving desired refractive outcomes.
Intended Use
This lens is intended for use by healthcare professionals and may not be available in all countries. Its innovative features and proven clinical benefits make it a leading choice for enhancing visual quality in patients with cataracts and astigmatism.
