Description
The HOYA Vivinex™ Toric Intraocular Lens (IOL) is a specialized lens designed for patients undergoing cataract surgery who also have pre-existing corneal astigmatism. Crafted from glistening-free hydrophobic acrylic, this lens offers exceptional clarity and includes UV and blue light filtering for enhanced eye protection.
Key Features
- Rotational Stability: Engineered for high rotational stability to ensure precise alignment and optimal visual outcomes.
- Reduced Opacification: Features a design that minimizes posterior capsule opacification (PCO), maintaining long-term clarity.
- Advanced Optic Design: The aspheric anterior surface and toric posterior surface work together to correct astigmatism and improve visual acuity.
Dimensions and Power
- Optic Diameter: 6.00 mm
- Overall Length: Typically 13.00 mm, with some models ranging from 12.5 mm to 13.00 mm.
- Spherical Power Range: +10.00 D to +30.00 D in 0.50 D increments.
- Cylinder Power Range: From 1.00 D to 6.00 D, tailored to meet various astigmatic needs.
Haptic Design
The lens includes a textured-rough haptic surface with a C-loop design, enhancing stability within the eye. Some models feature PMMA-modified haptics for additional support.
Injector System
Preloaded with the multiSert™ or iSert® injector system, the lens allows for a recommended incision size of 2.20 mm. The system supports both single-handed and two-handed injection techniques, providing flexibility during surgery.
Clinical Performance
- High Rotational Stability: Median rotation of 1.1° with 100% of lenses maintaining ≤5° rotation up to six months post-surgery.
- Glistening-Free Clarity: Supported by both laboratory and clinical data.
- Lower PCO Rates: Demonstrated through multiple randomized trials, leading to improved uncorrected visual acuity and patient satisfaction.
Indications for Use
This lens is intended for healthcare professionals to implant during cataract surgery in patients with corneal astigmatism. Proper preoperative assessment, accurate axis marking, and alignment are crucial for achieving the best outcomes.
Handling Notes
Postoperative care should include monitoring the alignment of the IOL to ensure continued visual performance. The HOYA Vivinex™ Toric IOL represents a sophisticated solution for enhancing visual clarity and reducing astigmatic challenges in cataract patients.
