Clinical Report: Evaluation of a Bessel Principle-Based Monofocal IOL
Overview
This study compares the optical qualities of the Hanita Extend IOL, utilizing Bessel beam technology, with the established TECNIS Eyhance IOL.
Background
Monofocal intraocular lenses (IOLs) are the standard in cataract surgery, providing excellent distance vision but often requiring reading glasses. Enhanced monofocal IOLs, such as the TECNIS Eyhance, aim to reduce this dependence by offering improved intermediate vision. The introduction of the Hanita Extend IOL, which employs a novel Bessel beam approach, represents a new option in this evolving landscape.
Data Highlights
No numerical data was provided in the source material.
Key Findings
The Hanita Extend IOL uses a conical axicon surface to create an elongated depth of focus.
Both the Hanita Extend and TECNIS Eyhance IOLs have the same refractive power of +20 D.
The TECNIS Eyhance lens features a higher-order aspheric anterior surface for continuous power progression.
The Hanita Extend lens corrects 0.13 μm of spherical aberration, while the Eyhance corrects 0.27 μm.
Optical benchmarking was conducted using the OptiSpheric IOL PRO2 to ensure compliance with ISO guidelines.
Clinical Implications
Clinicians should consider the optical properties of both the Hanita Extend and TECNIS Eyhance when discussing IOL options with patients.
Conclusion
The study provides a comparative analysis of two monofocal IOLs, highlighting the innovative approach of the Hanita Extend in enhancing intermediate vision. Further clinical evaluation is warranted to establish its performance in practice.
