Description

The HOYA Vivinex iSert XY1 Monofocal preloaded IOL is an advanced intraocular lens designed for use in cataract surgery. Manufactured by HOYA Surgical Optics, this lens features a glistening-free hydrophobic acrylic material, providing exceptional clarity and durability. Its design includes both UV and blue light filters, enhancing eye protection post-surgery.

Optic Design

• Aspheric Biconvex Optic: The lens incorporates a proprietary aspheric design with dual aspheric elements, reducing coma and improving image quality even off-axis.
• Edge Design: A square, thin, and textured optic edge minimizes posterior capsule opacification (PCO) and dysphotopsia, while partially compensating for corneal spherical aberration.

Haptic Design

The lens features a textured-rough haptic surface, promoting stability and reducing adhesion within the capsular bag. This design contributes to the lens's consistent performance and long-term positioning.

Surface Treatment

Active oxygen processing is applied to the lens surface, resulting in a smooth finish and low incidence of PCO. This treatment enhances the lens's longevity and visual outcomes.

Preloaded Injector System

The Vivinex iSert (multiSert™) preloaded delivery system allows for precise, single-use implantation. With a front injector tip diameter of 1.70 mm, it is ideal for micro-incision cataract surgery, recommending an incision size of 2.20 mm.

Technical Specifications

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm
• Power Range: +6.00 D to +30.00 D in 0.50 D increments
• Nominal A-Constant: 118.9

Optimized constants are available for various calculation formulas, ensuring accurate lens power selection.

Clinical Performance

The Vivinex iSert XY1 demonstrates high refractive predictability and significantly lower PCO and Nd:YAG capsulotomy rates compared to standard aspheric IOLs. It enhances intermediate vision, offering improved binocular visual acuity at 66 cm. The lens is designed for healthcare professionals, ensuring ease of use, consistent delivery, and stable positioning in the capsular bag.

Indications

This intraocular lens is intended to replace the eye’s natural lens during cataract surgery, providing a lifetime solution. For comprehensive indications and contraindications, healthcare providers should refer to the Instructions For Use.
