Description

The HOYA TORIC IOL, specifically the Vivinex™ Toric models XY1A and XY1A-SP, is a sophisticated intraocular lens designed by Hoya Surgical Optics. This lens is crafted for patients undergoing cataract surgery who also require correction for pre-existing corneal astigmatism.

Key Features

• Material and Design:
  The lens is made from a glistening-free hydrophobic acrylic material, ensuring long-term clarity. It includes both UV and blue light filters for enhanced eye protection. The biconvex optic design features an anterior aspheric surface and a posterior toric surface, aimed at improving image quality by compensating for corneal spherical aberration.

• Haptic Design:
  The C-loop haptic design with a textured surface ensures stable positioning within the eye. The optic diameter measures 6.00 mm, while the overall length is 13.00 mm, providing a secure fit.

• Power Specifications:
  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, with specific increments to match various astigmatism correction needs.

Advanced Features

• Injector System:
  The lens comes preloaded in the multiSert™ or iSert® injector system, allowing for a recommended incision size of 2.20 mm. This system supports both single-handed and two-handed injection techniques, enhancing surgical precision.

• Rotational Stability:
  The lens demonstrates exceptional rotational stability, with over 96% of lenses rotating 5° or less post-implantation. This stability is crucial for maintaining the desired visual outcomes.

Clinical Benefits

The Vivinex™ Toric lens is engineered to reduce postoperative refractive astigmatism and posterior capsule opacification (PCO). Its smooth surface and square optic edge design contribute to these outcomes, providing clearer vision post-surgery.

Intended Use

This intraocular lens is intended for use by healthcare professionals in cataract surgery, offering a reliable solution for patients with astigmatism. The precise engineering and advanced features of the HOYA TORIC IOL make it a valuable tool in achieving optimal visual results for patients.
