Description

The HOYA iSert 251 Monofocal Preloaded Intraocular Lens (IOL) is an advanced solution for cataract surgery, offering precision and ease of use. Designed by HOYA, this lens is crafted from hydrophobic acrylic material, providing excellent optical clarity and durability.

Key Features

• Aspheric Design: The lens features an aspheric, aberration-correcting design that enhances visual outcomes by reducing optical imperfections.
• Integrated Filters: Equipped with UV and blue light filters, it offers protection against harmful light exposure.
• Sharp Optic Edge: The sharp, square optic edge design helps in reducing posterior capsule opacification (PCO), ensuring long-term clarity.

Preloaded Injector System

The iSert 251 comes preloaded in a single-use injector system, allowing for controlled delivery through a microincision. This innovative system minimizes surgical impact and reduces the risk of contamination. The injector is compatible with microincision techniques, with a recommended incision size of 2.2–2.75 mm, and requires no rotation during delivery.

Haptic Design

• Material: The haptics are made from hydrophobic acrylic with blue PMMA tips, chemically bonded for stability.
• Configuration: Featuring a modified C-loop with 5° angulation, the haptics ensure secure positioning within the eye.

Dimensions and Power Range

• 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, accommodating a wide range of visual needs.

Implantation Process

The use of an ophthalmic viscoelastic device (OVD) is required during implantation. The process involves OVD infusion, cover removal, slider advancement, and controlled lens injection into the capsular bag. The system is designed for simplicity and predictability, with implantation recommended within 3 minutes after advancing the slider.

Regulatory Approvals

The HOYA iSert 251 is FDA approved and CE marked, available in regions including the USA, Japan, EMEA, and APAC. With over 10 million iSert lenses implanted worldwide, it boasts a strong track record of success.

Manufacturing Improvements

Past recalls due to trace metallic particulates have been addressed with manufacturing enhancements, ensuring the highest quality standards are maintained. This lens represents a reliable and effective choice for ophthalmic professionals seeking optimal surgical outcomes.
