Description

The HOYA TORIC IOL VIVINEX ISERT is a specialized intraocular lens designed for patients undergoing cataract surgery who also require astigmatism correction. This lens offers a sophisticated solution to enhance visual clarity by addressing pre-existing corneal astigmatism, making it a valuable tool for ophthalmic professionals.

Advanced Optic Design

• Aspheric Anterior Surface: The lens features a proprietary aspheric optic on the anterior surface, which helps to partially compensate for corneal spherical aberration and improve tolerance to coma.
• Toric Posterior Surface: The posterior surface is designed with a toric configuration to provide precise astigmatism correction.
• Biconvex Shape: The biconvex optic includes a square, thin, and textured edge to enhance performance.

Material and Filtering

Crafted from Vivinex™ glistening-free hydrophobic acrylic, the lens integrates UV and blue light filters to protect the eye. This material choice ensures long-term clarity and reduces visual disturbances.

Haptic Design

The lens includes a textured-rough haptic surface, promoting enhanced stability within the eye. With an optic diameter of 6.00 mm and an overall length of 13.00 mm, it is designed for optimal fit and performance.

Power Specifications

• Spherical Power Range: +10.00 to +30.00 D in 0.50 D increments.
• Cylinder Power (IOL Plane): 1.00 to 6.00 D (T2 to T9) with specific increments.
• Cylinder Power (Corneal Plane): 0.69 to 4.17 D with detailed increment specifications.

Optical Constants

The lens's nominal A-constant is 118.9, with optimized constants provided for various calculation formulas, including Haigis, Hoffer Q, Holladay 1, and SRK/T.

Injector System

The preloaded Vivinex™ iSert® or multiSert™ injector system facilitates implantation with a front injector tip outer diameter of 1.70 mm, recommending an incision size of 2.20 mm.

Clinical Benefits

The lens demonstrates outstanding rotational stability, with a median rotation of 1.1° and 100% of lenses maintaining ≤5° rotation at follow-up visits up to six months. Its design includes features to reduce posterior capsule opacification (PCO), such as active oxygen processing, a smooth surface, and a square optic edge.

Biocompatibility

Clinically proven to have low PCO rates, the lens's biocompatible design minimizes PCO formation, ensuring long-term clarity. The HOYA Toric Calculator is available for precise cylinder power calculation, utilizing the Abulafia-Koch Regression formula.

Professional Use

This product is intended for healthcare professionals, with availability varying by country. The HOYA TORIC IOL VIVINEX ISERT represents a high-quality option for achieving optimal visual outcomes in cataract surgery patients with astigmatism.
