Description
The HOYA Vivinex iSert XY1 Monofocal Preloaded Intraocular Lens (IOL) is a sophisticated solution designed for cataract surgery, offering enhanced visual outcomes through advanced technology. Crafted from glistening-free hydrophobic acrylic, this lens incorporates both UV and blue light filters, ensuring optimal eye protection.
Optic Design
The lens features a proprietary aspheric optic design with two distinct aspheric elements. This biconvex, anterior aspheric design is engineered to reduce spherical aberration and minimize coma, even in cases of decentration. The optic edge is square, thin, and textured with a radius of less than 10.0µm, aimed at reducing posterior capsule opacification (PCO) and dysphotopsia.
Surface and Haptic Design
The smooth, regular optic surface is complemented by a textured-rough haptic surface, enhancing grip and reducing adhesion. The active oxygen posterior surface processing further contributes to a low incidence of PCO.
Dimensions and Power Range
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
- Optical Power Range: +6.00 to +30.00 diopters (in 0.50 D increments)
Optical Constants
- Nominal A-constant: 118.9
- Optimized Constants for Calculation Formulas:
- Haigis: a0 = -1.0459, a1 = 0.2547, a2 = 0.2291
- Hoffer Q: pACD = 5.700
- Holladay 1: sf = 1.928
- SRK/T: A = 119.193
Injector System
The lens is preloaded in the Vivinex iSert (multiSert™) injector system, featuring a front injector tip outer diameter of 1.70 mm. This system is designed for a recommended incision size of 2.20 mm and allows for single-handed push or two-handed screw injection, enhancing surgical precision and ease.
Performance Benefits
The HOYA Vivinex iSert XY1 is renowned for its clarity, with significantly lower PCO rates compared to standard IOLs. It offers improved intermediate visual acuity at 66 cm and high refractive predictability, with 60% of outcomes within 0.25D of target, 87% within 0.50D, and 100% within 0.75D. The design minimizes dysphotopsia and enhances overall visual performance.
Intended Use
This lens is intended for implantation into the capsular bag through the incision wound tunnel, providing a reliable solution for patients with cataracts. Detailed stepwise instructions for preloaded delivery are included in the product documentation, ensuring proper handling by healthcare professionals.
