Alsanza Highlights Presbyopia correction with Fourier IOLs

Alsanza GmbH, a company known for its innovative ophthalmic products, continues to draw attention to its Alsee Fourier total presbyopia correcting intraocular lens (IOL), which features advanced Fourier Optic technology. This design aims to improve visual performance by optimizing light distribution and reducing common post-operative visual disturbances.

What is Fourier Optic Technology?

The advanced Fourier Optic Technology utilizes a unique undulatory diffractive profile to redefine visual outcomes. This advanced technology optimizes light management, minimizes scattering, and maintains continuous focus across varying lighting conditions.

Innovative Features and Benefits

Enhanced Light Transmission and Reduced Visual Disturbances

Ali Haidar, Distributor Manager EUSAM at Alsanza GmbH, emphasizes the significant benefits of the Fourier Optic IOL:

"Patients and surgeons typically seek an IOL that offers high light distribution with minimal light scattering, thereby reducing glare and halos. Fourier technology meets these expectations with its high light transmission rate to the retina, achieved through the undulatory diffractive patterns that minimize reflected and scattered light, providing continuous focus under all light conditions."

Continuous Vision and Improved Contrast Sensitivity

The Fourier Optic design comprises soft transition steps across the entire 6mm optical zone, supporting continuous vision at all distances and lighting conditions. Traditional trifocal designs often suffer from lower light transmission, increased halos and glare, and loss of contrast sensitivity in mesopic conditions. In contrast, Fourier IOL ensures higher light transmission, minimized halo effects, continuous focus, and enhanced contrast sensitivity even under low light conditions.

Patient and Surgeon Benefits

1. Minimized Glare and Halo: The unique undulatory pattern of Fourier Optic significantly reduces glare and halos, which are common issues with traditional overlapping Fresnel diffractive IOLs.

2. High Contrast Sensitivity: By efficiently distributing light over long distances and improving near-light distribution, Fourier Optic technology enhances contrast sensitivity, facilitating spectacle-free vision and better performance in low light conditions.

3. Spectacle Independence: Patients benefit from full independence from spectacles for near, intermediate, and distant vision, thanks to the balanced light distribution and continuous focus provided by the Fourier Optic design.

Clinical Validation

With over 500 successful surgeries and zero patient complaints, Fourier IOL has proven its efficacy and reliability. The technology's ability to maintain high Modulation Transfer Function (MTF) values at all distances further underscores its superior performance.

The Fourier IOL technology by Alsanza aims to advance ophthalmic care by providing an effective solution for presbyopia correction. With its innovative design and demonstrated benefits, Alsee Fourier IOL is setting a new benchmark in visual performance and patient outcomes.

By expanding its portfolio, Alsanza reinforces its dedication to innovation, ensuring diverse patient needs are met while upholding its commitment to advanced optical performance.
