Description

The HOYA Vivinex iSert XC1 is an advanced intraocular lens (IOL) system designed for use in cataract surgery, providing a reliable replacement for the eye’s natural lens. Developed by HOYA Corporation, this preloaded hydrophobic aspheric lens offers exceptional optical clarity and stability, tailored to meet the precise needs of ophthalmic professionals.

Material and Design

Crafted from glistening-free hydrophobic acrylic, the Vivinex™ material includes a UV filter to enhance visual performance while ensuring safety. The lens is MRI safe at both 1.5 and 3.0 Tesla, broadening its compatibility with various medical imaging requirements.

The lens features a proprietary aspheric optic design, known as Aspheric ABC Design, which incorporates two aspheric elements. This design minimizes spherical aberration and coma, even in cases of IOL decentration, leading to clearer vision outcomes. The optic edge is square, thin, and textured, reducing posterior capsule opacification (PCO) and dysphotopsia, while the smooth optic surface ensures clarity.

Haptic and Injector System

The haptic design shares the same hydrophobic acrylic material, with a textured-rough surface to enhance lens stability and reduce adhesion. The preloaded injector system, Vivinex iSert, includes a uni-directional slider and screw injector with a fixed grip, facilitating precise implantation. The injector tip's outer diameter is 1.70 mm, with a recommended incision size of 2.20 mm.

Specifications

Optimized constants for IOL power calculation include parameters for Haigis, Hoffer Q, Holladay 1, and SRK/T formulas, ensuring precise customization for individual patient needs.

Performance and Biocompatibility

The HOYA Vivinex iSert XC1 demonstrates outstanding optical clarity, with laboratory and clinical data indicating low PCO and Nd:YAG capsulotomy rates. The lens maintains long-term transparency, free from glistening, as evidenced by Grade 0 performance in studies.

The preloaded system is designed for ease of use, providing step-by-step handling instructions for consistent delivery. With no metallic components, the lens offers excellent biocompatibility, ensuring high-quality visual outcomes and patient satisfaction.
