Description
The HOYA Vivinex iSert XY1 is an advanced intraocular lens (IOL) system designed specifically for cataract surgery. Manufactured by HOYA Corporation, this preloaded lens system offers significant benefits for both patients and healthcare professionals.
Material and Design
Crafted from glistening-free hydrophobic acrylic, the lens incorporates UV and blue light filters, providing essential protection for the eye. The proprietary aspheric optic design features two distinct aspheric elements, enhancing visual clarity. The lens has a square, thin, and textured optic edge with a radius of less than 10.0µm, along with a smooth and regular optic surface.
Haptic Features
The haptic design includes a textured-rough surface, improving grip within the capsular bag and reducing adhesion to the optic surface. This design ensures stable positioning of the lens post-implantation.
Dimensions and Power Range
The optic diameter measures 6.00 mm, with 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, accommodating a wide variety of patient needs.
Delivery System
The Vivinex iSert® injector system is preloaded, featuring a front injector tip with an outer diameter of 1.70 mm. It allows for a recommended incision size of 2.20 mm, though it can be as small as 2.0 mm. The uni-directional slider and screw injector with a fixed grip facilitate precise and easy implantation.
Special Features
The lens undergoes active oxygen processing treatment, resulting in a smooth surface and square optic edge that significantly reduces posterior capsule opacification (PCO). It is designed to minimize glistening, with clinical studies showing a Grade 0 glistening level in long-term follow-ups. The lens is MRI safe at 1.5 and 3.0 Tesla, containing no metallic components.
Clinical Performance
Clinical trials have demonstrated lower PCO scores and Nd:YAG capsulotomy rates compared to other lenses, such as the AcrySof IQ SN60WF. This performance ensures long-term clarity and reduced need for additional surgical interventions.
Intended Use
Intended for use by healthcare professionals, the HOYA Vivinex iSert XY1 replaces the eye’s natural lens during cataract surgery. Its design and specifications may evolve due to ongoing technical development, and availability may vary based on local approvals.
For comprehensive indications and contraindications, healthcare providers should refer to the Instructions For Use. This innovative lens system represents a significant advancement in cataract surgery, offering enhanced visual outcomes and ease of use.
