Description

The HOYA iSert PY-60AD is an advanced intraocular lens (IOL) designed to enhance outcomes in cataract surgery. Developed by Hoya Surgical Optics, Inc., this preloaded, aspheric 3-piece lens is crafted for precise placement in the eye's capsular bag, effectively replacing the natural lens.

Key Features

• Material and Design: The lens features a hydrophobic acrylic material that is glistening-free, ensuring clarity and durability. Its aspheric, aberration-correcting monofocal design aims to improve visual quality by reducing optical aberrations.
• Dimensions: With an optic diameter of 6.0 mm and an overall length of 12.5 mm, the lens is engineered for optimal fit and performance.
• Haptic Configuration: The haptics are made from blue PMMA, chemically bonded with a modified C-loop and 5° angulation, providing stability within the eye.

Optical Enhancements

• Color and Composition: The lens is yellow and composed of 97% soft acrylic and 3% PMMA. It includes UV and blue light filters to protect the eye from harmful light exposure.
• Edge Design: A sharp optic edge is incorporated to reduce the likelihood of posterior capsule opacification (PCO), a common post-surgery complication.

Preloaded Injector System

The iSert preloaded injector system is a single-use, disposable tool that facilitates the lens's delivery through a 2.4 mm incision. This system enhances surgical efficiency by eliminating the need for cleaning and sterilizing reusable injectors, thereby reducing cross-contamination risks.

Manufacturing Excellence

The lens is lathe-cut and tumble polished, reflecting high manufacturing standards. Its A-constant is estimated at 118.4, with additional optimized constants available for various calculation formulas.

Clinical Benefits

With over 10 million implants worldwide since its launch in 2007, the hydrophobic acrylic material has a proven track record. The lens is designed for adult patients undergoing cataract surgery, with certain medical conditions requiring special consideration by the surgeon.

Long-Term Use

Expected to last 20 years, the lens typically does not require replacement unless medically indicated. A patient implant card is provided post-surgery for record-keeping.

Potential Considerations

While the lens offers significant benefits, potential adverse events may include wound leak, dry eye syndrome, capsule opacification, corneal complications, infection, and retinal detachment. Specifications and availability may vary by country, and surgeons should consider these factors when planning surgery.
