Description
The HOYA iSert 251 Monofocal Preloaded Intraocular Lens (IOL) is expertly designed for use in cataract surgery, offering advanced features tailored for ophthalmic professionals. This one-piece, aspheric lens is crafted from hydrophobic acrylic material, ensuring a glistening-free experience and enhanced visual clarity. Its innovative design includes integrated UV and blue light filters, providing essential protection for ocular health.
Advanced Lens Design
- Optic Diameter: 6.0 mm
- Overall Length: 12.5 mm
- Power Range: +6.00 to +30.00 diopters, in 0.50 D increments
The lens features a sharp, square optic edge to minimize posterior capsule opacification (PCO), while the Aspheric Balanced Curve (ABC) design enhances visual sharpness through aberration correction. The modified C-loop haptic configuration with chemically bonded blue PMMA tips ensures stable positioning within the eye.
Precision Manufacturing
Manufactured through a precise lathe-cut and pad-polished process, the lens offers reliable performance. The nominal A-constant of 118.4, along with optimized constants for various calculation formulas, supports accurate surgical outcomes.
Innovative Injector System
The fully preloaded, single-use iSert injector system is designed for microincision cataract surgery (MICS), compatible with incisions ranging from 2.2 to 2.75 mm. The screw-type plunger allows for controlled lens delivery, with bevel down insertion requiring no rotation. This system reduces contamination risk and eliminates the need for post-operative sterilization.
Handling and Implantation
The lens requires an ophthalmic viscoelastic device (OVD) for implantation, with recommended injection within three minutes after slider advancement. The stepwise handling process is designed to minimize friction, incision size, and surgically induced astigmatism, streamlining the surgical workflow.
Regulatory Approval and Track Record
With FDA approval and CE marking, the HOYA iSert 251 has a proven track record, with over 10 million units implanted worldwide. Its long-term clinical use underscores the reliability and effectiveness of the hydrophobic acrylic material, making it a trusted choice for healthcare professionals.
Streamlined Surgical Workflow
This single-use, disposable system is engineered to enhance the efficiency of cataract surgery, from preparation to insertion, reducing cross-contamination risks and supporting optimal surgical outcomes. The HOYA iSert 251 Monofocal Preloaded IOL stands as a testament to innovation and precision in ophthalmic care.
