Description
The HOYA Vivinex iSert XY1 Monofocal Preloaded Intraocular Lens (IOL) is a sophisticated solution designed for cataract surgery, offering exceptional clarity and stability. Crafted from glistening-free hydrophobic acrylic, this lens incorporates UV and blue light filters to protect the eye while enhancing visual performance.
Optic Design
The lens features a proprietary aspheric optic with two aspheric elements, effectively reducing spherical aberration and minimizing coma, even when decentered. Its square, thin, and textured optic edge is engineered to reduce posterior capsule opacification (PCO), ensuring long-term clarity. The smooth optic surface undergoes active oxygen processing treatment, further enhancing clarity and reducing PCO.
Haptic Design
The textured-rough haptic surface of the lens provides improved stability within the capsular bag, reducing adhesion and ensuring precise positioning. With an optic diameter of 6.00 mm and an overall length of 13.00 mm, the lens is available in a power range from +6.00 to +30.00 diopters, in 0.50 D increments.
Optical Constants
- Nominal A-constant: 118.9
- Optimized constants for various formulas:
- Haigis
- Hoffer Q
- Holladay 1
- SRK/T
These constants ensure accurate lens power calculations tailored to individual patient needs.
Delivery System
The preloaded Vivinex iSert or multiSert™ injector system facilitates consistent and predictable lens delivery. With a front injector tip outer diameter of 1.70 mm, it is recommended for an incision size of 2.20 mm. The system offers flexible delivery options, including single-handed push or two-handed screw injection.
Clinical Performance
Clinical studies demonstrate the lens's glistening-free performance, with significantly lower PCO and Nd:YAG capsulotomy rates compared to other lenses. The advanced optic design improves off-axis image quality by reducing coma, providing superior visual outcomes.
Intended Use
This lens is intended for use by healthcare professionals and is designed to replace the natural lens in patients undergoing cataract surgery. For comprehensive indications and contraindications, healthcare providers should refer to the Instructions For Use.
