Description

The HOYA iSert 251 Monofocal Intraocular Lens (IOL) is a sophisticated solution designed to enhance visual outcomes in cataract surgery. This one-piece, aspheric lens is crafted from hydrophobic acrylic, providing exceptional optical clarity and durability. Its advanced design includes an aberration-correcting optic and a Balanced Curve (ABC) feature, ensuring sharp and clear visual images.

Preloaded Injector System

The lens comes preloaded in a single-use injector system, streamlining the implantation process. This design minimizes handling errors and reduces the risk of contamination, making the procedure more efficient and predictable. The injector system is compatible with microincision techniques, requiring an incision size of just 2.2 to 2.4 mm.

Optical Features

• UV and Blue Light Filters: The lens includes integrated UV and blue light filters, offering additional protection to the eye.
• Square Optic Edge: Designed to minimize posterior capsule opacification (PCO), enhancing long-term visual clarity.

Haptic Design

The IOL features a modified C-loop haptic configuration with blue PMMA tips, providing stable positioning within the eye. The haptics are angulated at 5°, contributing to controlled unfolding and secure placement.

Dimensions and Power Range

• Optic Diameter: 6.0 mm
• Overall Length: 12.5 mm
• Power Range: +6.00 to +30.00 diopters in 0.50 D increments, accommodating a wide range of visual needs.

Manufacturing Excellence

Manufactured with precision, the lens is lathe-cut and pad-polished, ensuring high-quality performance. The A-constant nominal value is 118.4, with optimized constants available for various ophthalmic formulas, aiding in accurate lens power calculations.

Proven Track Record

With over 10 million IOLs implanted worldwide, the HOYA iSert 251 boasts a proven track record of success. It is FDA approved and CE marked, available across major regions including the USA, Japan, EMEA, and APAC.

Safety and Precautions

Prospective users should be aware of a past precautionary recall due to trace metallic particulates affecting units manufactured between October 2011 and January 2013. HOYA has since implemented manufacturing improvements to address these concerns.

This intraocular lens represents a blend of innovation and reliability, offering surgeons a trusted tool for achieving optimal surgical outcomes.
