Description

The HOYA Toric Intraocular Lens (IOL) is a specialized medical device designed for implantation during cataract surgery. Its primary function is to correct pre-existing corneal astigmatism, providing patients with improved visual outcomes. This lens is crafted from hydrophobic acrylic material, known for its glistening-free clarity, and includes UV and blue light filtering properties.

Design Features

• Optic Design: The lens features a biconvex, single-piece design with an aspheric anterior surface and a toric posterior surface. This design helps in partially compensating for corneal spherical aberration, enhancing visual quality.
• Haptic Design: The C-loop haptic design, with textured surfaces, ensures stable positioning within the eye. Some models include PMMA-modified haptics for additional stability.

Dimensions and Power

• Optic Diameter: Typically 6.00 mm.
• Overall Length: Varies between 12.5 mm and 13.00 mm depending on the model.
• Spherical Power Range: From +6.00 D to +30.00 D.
• Cylinder Power Range: At the IOL plane, from 1.00 D to 6.00 D, tailored to individual patient needs.

Advanced Injector System

The lens is available with a preloaded multiSert™ injector system, facilitating a smooth implantation process through a recommended incision size of 2.20 mm. This system enhances surgical efficiency and precision.

Clinical Performance

Rotational Stability

• Over 96% of lenses exhibit rotation of 5° or less post-implantation, ensuring consistent astigmatism correction.
• Mean axis rotation is minimal, contributing to reliable visual outcomes.

Visual Outcomes

• Significant reduction in postoperative refractive astigmatism, with many patients achieving uncorrected distance visual acuity of 20/40 or better.
• The lens design effectively minimizes posterior capsule opacification (PCO), reducing the need for additional corrective procedures.

Additional Model Features

Some models, like the Vivinex Gemetric Plus Toric, offer trifocal capabilities, providing clear vision at near, intermediate, and distance ranges. These models include a diffractive zone and axis orientation marks for enhanced performance in various lighting conditions.

Intended Use

The HOYA Toric IOL is intended for healthcare professionals managing patients with cataracts and corneal astigmatism. Comprehensive handling and maintenance guidelines are provided in the Instructions For Use, ensuring optimal outcomes and device longevity.
