Description

The HOYA TORIC IOL VIVINEX ISERT is an advanced intraocular lens designed to enhance visual outcomes for cataract surgery patients with astigmatism. This lens is crafted from glistening-free hydrophobic acrylic, ensuring clarity and longevity. Its integrated UV and blue light filters provide additional protection for the eye.

Optic Design

• Biconvex Shape: Features an aspheric anterior surface and a toric posterior surface.
• Edge Design: The square, thin, and textured optic edge reduces posterior capsule opacification (PCO).
• Proprietary Aspheric Optic: Partially compensates for corneal spherical aberration and improves tolerance to coma, enhancing image quality.

Haptic Design

• Textured Surface: The haptic design includes a textured-rough surface, promoting enhanced stability within the eye.

Dimensions

• Optic Diameter: 6.00 mm
• Overall Length: 13.00 mm

Power Specifications

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

Optical Constants

• Nominal A-Constant: 118.9
• Optimized Constants: Various configurations for Haigis, Hoffer Q, Holladay 1, and SRK/T formulas.

Injector System

The lens is preloaded in the Vivinex iSert® or multiSert™ system, featuring a front injector tip with an outer diameter of 1.70 mm. The recommended incision size is 2.20 mm, facilitating ease of insertion.

Surface Treatment

• Active Oxygen Processing: Ensures a smooth, regular IOL surface.
• Square Optic Edge: Designed to minimize PCO.

Rotational Stability

• Median Rotation: Between 1.1° to 1.54° with 100% of lenses rotating ≤5° at follow-ups up to 6 months.
• High Stability: Over 96% of lenses maintain rotation ≤5°, even in eyes with high axial lengths.

Clinical Benefits

• Clarity: Proven glistening-free clarity with low PCO incidence.
• Design: Proprietary aspheric optic for improved image quality.
• Target Audience: Intended for healthcare professionals treating cataract surgery patients with astigmatism.

Additional Features

The HOYA Toric Calculator supports cylinder power calculation, utilizing the Abulafia-Koch Regression formula for posterior corneal astigmatism estimation. The lens is CE marked (CE 0483), indicating compliance with European health, safety, and environmental protection standards.
