Description
The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed to enhance visual outcomes for patients undergoing cataract surgery with astigmatism. This lens is crafted from glistening-free hydrophobic acrylic, ensuring long-term optical clarity and integrating both UV and blue light filters for comprehensive eye protection.
Optical Design
- Biconvex Structure: Features a biconvex optic with an anterior aspheric surface and a posterior toric surface.
- Edge Design: The sharp, textured optic edge is engineered to reduce posterior capsule opacification (PCO).
- Aspheric Optic Design: Proprietary design partially compensates for corneal spherical aberration, improving tolerance to coma.
Stability and Precision
- Haptic Design: The lens includes textured-rough haptic surfaces made from the same acrylic material, enhancing rotational stability.
- Dimensions: Optic diameter is 6.00 mm with an overall length of 13.00 mm.
- Power Ranges: Spherical power ranges from +10.00 to +30.00 diopters, with cylinder power tailored for precise astigmatism correction.
Injector System
The lens comes preloaded in the Vivinex™ iSert® or multiSert™ injector system, facilitating a recommended incision size of 2.20 mm. The multiSert™ system offers versatile injection methods, allowing for single-handed or two-handed operation.
Clinical Performance
- Rotational Stability: Demonstrates exceptional stability with median rotation at 1.1°, ensuring precise alignment.
- PCO Reduction: Active oxygen processing and a smooth IOL surface contribute to reduced PCO formation.
Compatibility and Indications
- Toric Calculator: Compatible with the HOYA Toric Calculator, utilizing the Abulafia–Koch Regression formula for accurate astigmatic effect estimation.
- Patient Suitability: Ideal for patients with cataracts and pre-existing corneal astigmatism, suitable for microincision cataract surgery.
This lens is designed to provide high biocompatibility, clarity, and precise visual correction, making it a valuable option for enhancing post-surgical visual outcomes. The advanced features and reliable performance of the HOYA TORIC IOL VIVINEX ISERT support its role in achieving optimal patient satisfaction in cataract surgery.
