Description

The HOYA iSert 251 Monofocal Preloaded Intraocular Lens (IOL) is expertly designed for use in cataract surgery, offering a reliable replacement for the eye's natural lens. Crafted from hydrophobic acrylic material, this lens features a glistening-free, aspheric optic with an Aspheric Balanced Curve (ABC) design. These attributes enhance visual sharpness and correct aberrations, providing patients with improved visual outcomes.

Advanced Optical Features

• UV and Blue Light Filters: Integrated within the lens, these filters help protect the eye by controlling blue light exposure, with a yellow tint for added effectiveness.
• Biconvex Shape: The lens's biconvex shape is lathe-cut and pad-polished, ensuring high-quality optics.

Precision Haptic Design

The lens includes a modified C-loop haptic design with 5° angulation, made from hydrophobic acrylic with chemically bonded blue PMMA tips. This configuration ensures stable in-the-bag fixation and reduces posterior capsule opacification (PCO) through a 360° sharp, square optic edge.

Dimensions and Power

• 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

Innovative Injector System

Preloaded in the iSert single-use, disposable injector system, the lens allows for controlled and consistent delivery. This system is compatible with microincision cataract surgery (MICS), suitable for incision sizes between 2.2 mm and 2.8 mm. The screw-type plunger mechanism facilitates controlled injection, minimizing friction and surgically induced astigmatism.

Handling and Implantation

The lens requires an ophthalmic viscoelastic device (OVD) for implantation and is designed for easy handling with high predictability. Key steps include OVD infusion, cover removal, slider advancement, and controlled lens injection into the capsular bag, where it self-centralizes.

Regulatory Approvals and Track Record

The HOYA iSert 251 IOL is both FDA approved and CE marked, with availability across the USA, Japan, EMEA, and APAC regions. With over 10 million units implanted worldwide, it boasts a proven track record of safety and effectiveness. Manufacturing improvements have been implemented following a past recall, ensuring continued high standards.

This product's design and performance characteristics make it a trusted choice for ophthalmic professionals seeking reliable outcomes in cataract surgery.
