Description

The HOYA Vivinex™ Toric Intraocular Lens (IOL), Model XY1A-SP, is a specialized lens designed to enhance visual outcomes for patients undergoing cataract surgery with pre-existing astigmatism. Crafted from hydrophobic acrylic material, this lens offers glistening-free clarity and incorporates both UV and blue light filters for comprehensive eye protection.

Key Features

• Advanced Optic Design: The lens features a biconvex, single-piece structure with an aspheric anterior surface and a toric posterior surface. This design aims to compensate for corneal spherical aberration, enhancing image quality and reducing visual disturbances.

• Dimensions: With an optic diameter of 6.00 mm and an overall length of 13.00 mm, the lens is engineered for precise fitting and performance.

• Haptic Stability: The C-loop haptic design, complete with textured surfaces and axis orientation marks, ensures exceptional rotational stability. Clinical data indicates that over 96% of these lenses rotate ≤5° post-implantation, maintaining alignment for optimal vision correction.

Performance Benefits

• Reduced Posterior Capsule Opacification (PCO): The lens's smooth surface, active oxygen processing, and square optic edge are designed to minimize PCO, contributing to long-term visual clarity.

• Proprietary Aspheric Optic Design: This feature improves tolerance to coma, providing clearer and sharper vision.

Power Specifications

• Spherical Power Range: Available from +10.00 D to +30.00 D in 0.50 D increments.
• Cylinder Power Range: At the IOL plane, it ranges from 1.00 D to 6.00 D, with specific increments for precise astigmatism correction.

Injector System

The lens comes with the preloaded multiSert™ injector system, offering both single-handed push and two-handed screw injection options. The system's design includes a front injector tip with an outer diameter of 1.70 mm, suitable for a recommended incision size of 2.20 mm, ensuring precise and controlled lens delivery.

Clinical Indications

The HOYA Vivinex™ Toric IOL is intended for use by healthcare professionals in cataract surgeries, specifically targeting the correction of corneal astigmatism. Its innovative features and proven performance make it a reliable choice for achieving desired surgical outcomes.
