Description

The HOYA Toric Intraocular Lens (IOL) is a specialized medical device designed to enhance visual outcomes for cataract patients with pre-existing corneal astigmatism. Crafted from hydrophobic acrylic material, this lens offers exceptional clarity by being glistening-free and incorporates UV and blue light filtering for added eye protection.

Design Features

• Optic Design: The lens features a biconvex, single-piece structure with a square, thin, and textured optic edge. Its anterior aspheric surface partially compensates for corneal spherical aberration, while the posterior toric surface effectively corrects astigmatism.
• Haptic Design: Equipped with C-loop haptics, the lens ensures stable positioning within the eye. Some models include PMMA-modified haptics for enhanced stability.

Dimensions and Power

• Optic Diameter: 6.00 mm
• Overall Length: Ranges from 12.5 mm to 13.00 mm
• Spherical Power Range: +10.00 D to +30.00 D in 0.50 D increments
• Cylinder Power Range: At the IOL plane, 1.00 D to 6.00 D, with specific increments for precise correction

Implantation System

The lens is compatible with the preloaded multiSert™ or iSert® injector system, facilitating a smooth implantation process. The recommended incision size is 2.20 mm, aligning with the front injector tip's outer diameter of 1.70 mm.

Performance Highlights

• Rotational Stability: Clinical studies indicate that over 96% of these lenses rotate ≤5° post-implantation, with a median rotation of just 1.1° up to six months after surgery.
• Posterior Capsule Opacification (PCO): The lens design significantly reduces PCO, with lower scores and Nd:YAG capsulotomy rates compared to other IOLs.
• Optical Quality: Proprietary aspheric optic design enhances image quality and reduces coma, ensuring long-term visual clarity.

Surgical Considerations

For optimal results, precise alignment to the intended axis is crucial. The lens's tacky surface aids adherence to the posterior capsule, minimizing postoperative rotation. Thorough removal of viscoelastic substances during surgery is recommended to maintain lens position.

Intended Audience

This intraocular lens is intended for use by healthcare professionals specializing in cataract surgery, providing a reliable solution for patients with corneal astigmatism. Its advanced features aim to deliver superior visual outcomes, making it a valuable addition to ophthalmic surgical practices.
