Description

The HOYA iSert 251 Monofocal Preloaded Intraocular Lens (IOL) is a sophisticated solution designed for cataract surgery, offering healthcare professionals enhanced precision and ease of use. This lens features an aspheric, aberration-correcting optic design that aims to improve visual sharpness, complemented by integrated UV and blue light filters for added eye protection.

Key Features

• Optic Design: The lens includes a sharp, square optic edge intended to reduce posterior capsule opacification (PCO), contributing to clearer vision post-surgery.
• Material Composition: Crafted from hydrophobic acrylic, both the optic and haptic materials are designed for durability, with the haptic tips chemically bonded with blue PMMA for stability.

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, allowing for tailored vision correction.

Injector System

The lens is delivered using the preloaded iSert injector system, a single-use, dry system that supports microincision techniques with incision sizes ranging from 2.2 to 2.75 mm. The injector features a screw-type plunger for controlled lens delivery, designed to minimize friction and surgically induced astigmatism.

Surgical Efficiency

This system is engineered to enhance surgical efficiency by reducing handling errors and contamination risks. The lens unfolds slowly upon insertion, requiring careful handling, and is self-centralizing within the capsular bag, promoting optimal positioning.

Regulatory Compliance

The HOYA iSert 251 IOL is both FDA approved and CE marked, with a proven track record of over 10 million units implanted worldwide. This extensive history underscores its reliability and effectiveness in improving patient outcomes in cataract surgery.

Handling Instructions

For optimal results, the use of an ophthalmic viscoelastic device (OVD) is recommended during insertion. The typical lens insertion time is approximately 30 seconds, with a stepwise loading and implantation process to ensure precision.

Manufacturing Excellence

Manufactured with meticulous attention to detail, the lens is lathe-cut and pad-polished, featuring a modified C-loop haptic design with 5° angulation for stable positioning within the eye. This design contributes to the lens's long-term performance and patient satisfaction.

The HOYA iSert 251 Monofocal Preloaded IOL represents a blend of advanced optical technology and practical surgical application, making it a valuable asset in modern ophthalmic procedures.
