Description
The HOYA Vivinex iSert XC1 is a sophisticated intraocular lens (IOL) designed for use in cataract surgery. Crafted by HOYA, this lens is preloaded and single-piece, featuring an aspheric design that enhances visual outcomes by reducing spherical aberration. Its unique Vivinex™ material is glistening-free and hydrophobic, equipped with a UV filter to ensure long-term clarity and protection.
Optic and Edge Design
The lens boasts a proprietary aspheric optic design with dual aspheric elements, minimizing coma even in cases of IOL decentration. Its square, thin, and textured optic edge is engineered to reduce posterior capsule opacification (PCO) and dysphotopsia, with a radius of curvature less than 10.0 µm. The posterior surface undergoes active oxygen processing, creating a smooth and regular optic surface that further diminishes PCO.
Haptic and Stability Features
The textured-rough haptic surface of the Vivinex iSert XC1 enhances stability within the capsular bag while reducing adhesion. This design contributes to the lens's overall performance and longevity, making it a reliable choice for ophthalmic professionals.
Preloaded Injector System
The lens comes with the Vivinex iSert® injector system, featuring a 1.70 mm injector tip outer diameter. The system includes a uni-directional slider and screw injector with a fixed grip, recommended for an incision size of 2.20 mm. This comprehensive system includes an injector tip, slider, rod, and injector knob, ensuring precise and consistent delivery.
Technical Specifications
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
- Power Range: +6.00 to +30.00 diopters (in 0.50 D increments)
- A-Constant (Nominal): 118.9
Optimized constants for IOL power calculation are provided for various formulas, including Haigis, Hoffer Q, Holladay 1, and SRK/T, allowing for tailored surgical planning.
MRI Compatibility
The lens contains no metallic components, making it safe for use in MRI environments at 1.5 and 3.0 Tesla. This feature adds to its versatility and appeal in diverse clinical settings.
Clinical Performance
Clinically, the HOYA Vivinex iSert XC1 demonstrates exceptional performance with low PCO rates and minimal Nd:YAG capsulotomy rates compared to other IOLs. It is designed for long-term optical clarity and stability, intended for lifetime implantation. The lens is supplied in a preloaded system, facilitating consistent and simple delivery.
Professional Use
This intraocular lens is intended for use by healthcare professionals, with design and specifications subject to change due to ongoing technical development. For comprehensive indications and contraindications, professionals are advised to consult the official Instructions For Use.
