Description

The HOYA iSert PY-60AD is an advanced intraocular lens (IOL) designed for use in cataract surgery, offering significant enhancements in visual clarity and performance. Manufactured by HOYA Surgical Optics, Inc., this lens is intended for implantation in the capsular bag of the eye, providing a monofocal solution to restore vision.

Key Features

• Aspheric Optic Design: The lens features an aspheric, aberration-correcting optic that enhances visual outcomes by reducing optical imperfections. This design includes a sharp optic edge aimed at minimizing posterior capsule opacification (PCO), a common post-surgery complication.

• Material Composition: The optic is made from hydrophobic acrylic with a yellow tint, incorporating a UV filter and blue light filter for added protection. The haptics are crafted from blue PMMA and are chemically bonded to the optic, ensuring stability and durability.

• 3-Piece Configuration: The lens includes modified C-loop haptics with a 5° angulation, contributing to secure placement within the eye.

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 for precise customization to patient needs.

Manufacturing Excellence

The lens is crafted using advanced techniques such as lathe-cutting and tumble polishing, ensuring high-quality surface finish and optical precision. The estimated A-constant is 118.4, with optimized constants available for various calculation formulas, aiding in accurate surgical planning.

Delivery System

The HOYA iSert PY-60AD comes with a fully preloaded iSert injector system, designed for single-use. This system simplifies the implantation process, enhancing surgical efficiency and reducing the risk of contamination. Key preparation steps include OVD infusion and precise operation of the injector's slider and knob.

Longevity and Global Reach

With over 10 million IOLs implanted worldwide since 2007, HOYA lenses are renowned for their reliability and long-term performance. The expected lifetime of the lens is approximately 20 years, with replacement typically unnecessary unless medically indicated.

Safety Considerations

While there are no known contraindications for adults, certain medical conditions may require special consideration by the surgeon. Potential adverse events are similar to those associated with other IOLs and include issues such as wound leak, dry eye syndrome, and changes in intraocular pressure. However, no significant trends in complaints have been identified, and no corrective actions have been deemed necessary.

This comprehensive design and delivery approach make the HOYA iSert PY-60AD a trusted choice for ophthalmic professionals seeking to achieve optimal outcomes in cataract surgery. Its innovative features and proven track record underscore its role in advancing patient vision care.
