Description
The HOYA TORIC IOL, including models such as Vivinex™ Toric XY1A, XY1A-SP, and NS60YT, is a specialized intraocular lens designed to correct astigmatism during cataract surgery. Crafted from hydrophobic acrylic, this lens offers a glistening-free experience, providing long-term clarity. It incorporates both UV and blue light filters to enhance visual protection.
Optic Design
- Biconvex Optic: Features a square, thin, and textured edge.
- Aspheric Anterior Surface: Partially compensates for corneal spherical aberration.
- Toric Posterior Surface: Specifically designed for astigmatism correction.
- Smooth Surface: Includes axis orientation marks for precise alignment.
Haptic Design
The lens boasts a textured-rough haptic surface, available in C-loop or anchor wing-haptic designs, depending on the model. Some models feature PMMA-modified haptics, enhancing stability within the eye.
Dimensions
- Optic Diameter: 6.00 mm
- Overall Length: Ranges from 12.5 mm to 13.00 mm
Power Range
- Spherical Power: +10.00 D to +30.00 D, in 0.50 D increments (some models start at +6.00 D).
- Cylinder Power at IOL Plane: 1.00 D to 6.00 D, with specific increments for precise correction.
Injector System
Equipped with a preloaded multiSert™ or Vivinex™ iSert® injector system, the lens allows for a recommended incision size of 2.20 mm. The system includes an adjustable insert shield for precise insertion.
Key Features
- Proprietary Aspheric Optic Design: Enhances image quality and tolerance to coma.
- Surface and Edge Design: Reduces posterior capsule opacification (PCO).
- Rotational Stability: Demonstrates outstanding stability with minimal rotation post-implantation.
Clinical Performance
The HOYA TORIC IOL has shown effective astigmatism correction, stable visual outcomes, and a significant reduction in postoperative refractive astigmatism. It is designed for healthcare professionals treating patients with cataracts and pre-existing corneal astigmatism, ensuring precise delivery and stable positioning within the capsular bag.
Indications
This lens is intended for use by healthcare professionals, offering a reliable solution for patients with cataracts and corneal astigmatism, aiming to provide clear and stable visual results.
