Description

The HOYA iSert PY-60AD is an advanced aspheric, monofocal intraocular lens (IOL) designed to enhance visual outcomes for patients undergoing cataract surgery. Manufactured by HOYA Surgical Optics, Inc., this lens is crafted from hydrophobic acrylic with a unique design that includes a yellow optic and blue PMMA haptics, providing a robust and reliable structure.

Key Features

• Aberration-Correcting Design: The aspheric optic design of the HOYA iSert PY-60AD aims to correct aberrations, offering clearer and sharper vision post-surgery.
• UV and Blue Light Filtering: Equipped with filters for UV and blue light, this lens helps protect the eye from potential light-induced damage.
• Sharp Optic Edge: The lens features a sharp optic edge intended to reduce posterior capsule opacification (PCO), a common post-surgical complication.

Innovative Delivery System

The fully preloaded iSert delivery system is a standout feature, simplifying the surgical process by eliminating the need for cleaning and sterilizing reusable injectors. This single-use device is designed for seamless implantation, enhancing surgical efficiency and reducing potential contamination risks.

Dimensions and Specifications

• Optic Diameter: 6.0 mm
• Overall Length: 12.5 mm
• Power Range: Available from +6.00 to +30.00 diopters in 0.50 D increments, allowing customization to individual patient needs.

Placement and Longevity

Intended for placement in the capsular bag of the eye, the HOYA iSert PY-60AD is lathe-cut and tumble polished for precision. Its modified C-loop haptic configuration with 5° angulation ensures stable positioning within the eye. With an expected lifetime of 20 years, this lens offers long-term performance, requiring replacement only if medically indicated.

Regulatory and Clinical Background

CE marked (CE 0123), the HOYA iSert PY-60AD has been in use since 2007, with over 10 million implants worldwide. It boasts a strong safety profile, though potential adverse events such as wound leak, dry eye syndrome, and changes in intraocular pressure should be considered by healthcare professionals.

Calculation Constants

The lens provides estimated A-constants and additional optimized constants for various calculation formulas, supporting precise surgical planning and implantation outcomes.

Clinical Considerations

While there are no known contraindications for adults, certain medical conditions may require special consideration by the surgeon. Awareness of potential adverse events such as retinal detachment, macular degeneration, and infection is crucial for informed surgical decision-making.

The HOYA iSert PY-60AD represents a sophisticated option in intraocular lens technology, offering tailored visual correction and ease of use for ophthalmic surgeons worldwide.
