of adaptive optics components
Imagine Eyes’ adaptive optics (AO) components deliver unparalleled performance for measuring ocular wavefront errors, simulating ophthalmic lenses, and enhancing optical resolution of retinal imaging systems.
They enable an AO technology which performs flawlessly when applied to living eyes, and can readily be incorporated in various system configurations.
The AOkit™ is a complete set of AO components specially designed for industrials and researchers who develop ophthalmic instrumentation. It includes:
Each component of the AOkit ideally complements each other, and all of them are seamlessly integrated in a broad variety of systems.
for use with living eyes
in a broad variety of opthalmic systems
New approach for adaptive optics
WaveTune, the successor of Casao™, is a unique application that combines wavefront measurement and correction features with extensive instrument calibration and diagnostics functions. It provides an ergonomic, all-in-one adaptive optics PC workspace.
Included in Imagine Eyes’ AOkit, WaveTune is perfectly adapted to the mirao 52-e deformable mirror and the HASO4 first wavefront sensor. In many cases, it is the only software tool that you need to drive your AO system in both closed and open loop.
Whether you’re an established expert in adaptive optics or just getting started, you’ll be up and running quickly thanks to WaveTune’s user-friendly, feature rich environment.

In all patients, AO images showed dark elements that were smaller than what could be resolved by fundus imaging and OCT
The rtx1 demonstrates that, unlike the common belief, performing AO retinal imaging can be as easy as standard retinal imaging
We, for the first time, visualized longitudinal changes during the recovery of cone photoreceptors in the eyes of VKH patients
The image resolution achieved by this technology is superior to that of any other current diagnostic tool.
Adaptive optics retinal imaging provided non-invasive and sensitive information on the pathologic disruption of the cone mosaic, even in the absence of subjective (visual loss) or objective (diagnostic imaging) abnormalities.
