Description

The HOYA TORIC IOL XY1AT9, part of the Vivinex™ Toric series, is a specialized intraocular lens designed for precise astigmatism correction during cataract surgery. Crafted from glistening-free hydrophobic acrylic, it features integrated UV and blue light filters, ensuring long-term clarity and protection.

Optic Design

• Biconvex Structure: The lens boasts a biconvex optic with an aspheric anterior surface and a toric posterior surface.
• Edge Design: Its square, thin, and textured optic edge is engineered to partially compensate for corneal spherical aberration, enhancing visual quality.
• Aberration Compensation: Improves tolerance to coma, contributing to superior image quality.

Haptic Design

• Textured Surface: The haptic design includes a textured-rough surface, providing enhanced stability within the eye.
• Active Oxygen Processing: The posterior surface undergoes active oxygen processing, reducing posterior capsule opacification (PCO) for clearer vision post-surgery.

Dimensions

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm

Power Range

• Spherical Power: Available from +10.00 to +30.00 D in 0.50 D increments.
• Cylinder Power: Ranges from 1.00 to 6.00 D at the IOL plane, with precise increments for tailored correction.

Rotational Stability

• Exceptional Stability: Demonstrates a median rotation of 1.1°, with over 96% of lenses rotating ≤5° post-operation.
• Consistent Positioning: Ensures stable postoperative positioning, crucial for effective astigmatism correction.

Injector System

• Preloaded Systems: Compatible with multiSert™ or Vivinex™ iSert® systems.
• Injector Tip Diameter: 1.70 mm, with a recommended incision size of 2.20 mm.
• Flexible Injection: Offers single-handed push or two-handed screw injection options.

Axis Orientation

• Orientation Marks: Axis orientation marks on the posterior surface facilitate accurate alignment during implantation.

Optical Constants

• A-Constant: Nominal A-constant of 118.9, with optimized constants for various calculation formulas, enhancing surgical planning accuracy.

Clinical Benefits

• Reduced PCO: The lens design and material significantly lower PCO and Nd:YAG capsulotomy rates compared to other IOLs.
• Aspheric Optic Design: Provides improved image quality, supported by laboratory and clinical data.
• Biocompatibility: Ensures long-term clarity and stability, making it a reliable choice for ophthalmic surgeons.

The HOYA TORIC IOL XY1AT9 is intended for those seeking precise astigmatism correction with stable postoperative outcomes, offering advanced optical performance and enduring clarity.
