Description

The HOYA Vivinex iSert XC1 is an advanced intraocular lens (IOL) designed for use in cataract surgery. Crafted by HOYA Corporation, this lens features a glistening-free hydrophobic acrylic material, ensuring clear vision without unwanted reflections. The model XC1 includes a UV filter and is free of metallic components, making it safe for MRI procedures at 1.5 and 3.0 Tesla.

Optic Design

The lens incorporates HOYA's proprietary aspheric optic design, known as "ABC Design," which includes two aspheric elements. This design reduces spherical aberration and minimizes coma, even if the lens is decentered. The optic edge is square, thin, and textured with a radius of less than 10.0μm, which helps reduce posterior capsule opacification (PCO) and dysphotopsia. The smooth and regular optic surface further enhances visual outcomes.

Haptic Design

The haptic design features a textured-rough surface that improves stability and grip, preventing sticking when folded. This design contributes to the overall stability of the lens once implanted.

Surface Treatment

Active oxygen processing on the posterior surface of the lens is employed to reduce PCO, enhancing long-term clarity.

Delivery System

The Vivinex iSert XC1 comes with a preloaded injector system, either Vivinex iSert® or multiSert™, featuring an ergonomic design. The system includes a precision tip, irreversible slider, and screw mechanism for controlled and reproducible lens delivery. The front injector tip has an outer diameter of 1.70 mm, with a recommended incision size of 2.20 mm, which can be as low as 2.0 mm.

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)

Performance

The Vivinex iSert XC1 demonstrates exceptional glistening resistance, with laboratory and clinical studies showing a Grade 0 performance. It also boasts low PCO rates, with effective long-term PCO inhibition, as evidenced in both animal and human studies. Compared to other lenses like AcrySof IQ, it has significantly lower PCO and Nd:YAG capsulotomy rates.

Optical Quality

The lens provides high image quality and clarity, partially compensating for corneal spherical aberration and offering greater tolerance to coma than standard aspheric designs. These features ensure consistent optical performance and longevity, designed to last a lifetime.

Intended Use

The HOYA Vivinex iSert XC1 is intended for implantation by healthcare professionals during cataract surgery, offering a reliable solution for enhancing visual outcomes. Design and specifications may evolve with ongoing technical development.
