Description

The HOYA iSert PY-60AD is a monofocal intraocular lens (IOL) specifically designed to enhance visual outcomes for patients undergoing cataract surgery. Crafted by HOYA, this lens features an aspheric, aberration-correcting optic design that aims to provide clear and precise vision.

Material and Design

• Optic Material: Hydrophobic acrylic with yellow tint, comprising 97% soft acrylic.
• Haptic Material: Blue PMMA, chemically bonded, making up 3% of the composition.
• Design: A 3-piece IOL with a sharp optic edge to help reduce posterior capsule opacification (PCO).

The lens includes a modified C-loop haptic configuration with 5° angulation, enhancing stability within the eye. The manufacturing process involves lathe-cutting and tumble polishing, ensuring high-quality finish and performance.

Advanced Features

• UV and Blue Light Filtering: Protects the eye from harmful light exposure.
• Optic Diameter: 6.0 mm
• Overall Length: 12.5 mm

These features contribute to the lens's ability to provide long-term visual clarity and protection.

Preloaded Injector System

The iSert PY-60AD comes fully preloaded in the iSert injector system, simplifying the surgical process by eliminating the need for cleaning and sterilization of reusable injectors. The front injector tip has an outer diameter of 1.89 mm, designed for precise and controlled insertion.

Power Range and A-Constant

• Power Range: +6.00 to +30.00 diopters, available in 0.50 D increments.
• A-Constant: Estimated at 118.4, with optimized constants available for various calculation formulas.

These specifications allow for tailored vision correction to meet individual patient needs.

Intended Use

The lens is intended for placement in the capsular bag during cataract surgery, suitable for adult patients. Handling instructions for preparation and injection are provided to ensure proper use.

Longevity and Safety

With an expected lifetime of 20 years, replacement is generally not required unless medically indicated. While there are no known contraindications for adults, potential adverse events are similar to those associated with other IOLs, such as wound leak, dry eye syndrome, and changes in intraocular pressure.

Global Impact

Since its launch in 2007, over 10 million HOYA IOLs have been implanted worldwide, reflecting the trust and reliability placed in this advanced optical solution. Continuous technical development may lead to design and specification enhancements, further advancing its performance.
