Description

The HOYA iSert 251 Monofocal Preloaded Intraocular Lens (IOL) is a sophisticated solution designed to enhance cataract surgery outcomes. This single-use, disposable system is meticulously engineered to streamline the surgical process, offering a seamless transition from lens preparation to insertion. By minimizing the risk of cross-contamination and eliminating the need for postoperative sterilization, it ensures a safer, more efficient surgical environment.

Advanced Optic Design

• Aspheric, Aberration-Correcting Optic: Provides sharp, clear visual images.
• Balanced Curve (ABC): Enhances visual clarity.
• Square, Sharp Optic Edge: Helps reduce posterior capsule opacification (PCO).
• Glistening-Free Material: Ensures long-term clarity.

Material and Haptic Design

Crafted from hydrophobic acrylic, the lens features a yellow, blue-blocking filter to protect against UV and blue light. The modified C-loop haptic design, with integrated blue PMMA tips, offers stability with a 5° angulation, ensuring precise positioning within the eye.

Dimensions and Power Range

• Optic Diameter: 6.0 mm
• Overall Length: 12.5 mm
• Power Range: +6.00 D to +30.00 D in 0.50 D increments

These specifications allow for tailored visual correction, accommodating a wide range of patient needs.

Preloaded Injector System

The iSert injector system is designed for implantation through a 2.4 mm incision, enhancing compatibility with microincision cataract surgery (MICS). The front injector tip's outer diameter is reported as either 1.82 mm or 1.93 mm, emphasizing the need for confirmation with the latest documentation. This system reduces friction and minimizes surgically induced astigmatism, contributing to optimal surgical outcomes.

Handling and Implantation

The lens is implanted using a precise, step-by-step method:

1. Remove the injector from the pouch using the handling tab.
2. Infuse ophthalmic viscoelastic device (OVD) into the injector.
3. Advance the slider and implant the lens within 3 minutes.
4. Use the screw plunger to inject the lens through the incision.
5. Ensure proper release and positioning of the lens in the capsular bag.

Regulatory Approvals and Availability

The HOYA iSert 251 is FDA approved and CE Mark certified, available across the USA, Japan, EMEA, and APAC regions. Its design enhances surgical efficiency, mechanical reliability, and microbiologic safety, making it a trusted choice for ophthalmic professionals worldwide.
