Multi-functional optical coherence tomography (OCT) system for corneal assessment

Capable to measure various corneal biomechanical properties

Optical coherence tomography (OCT) is a non-invasive, non-contact imaging technology which is developed to obtain tissue cross-section image with high resolution. PolyU’s research team has successfully developed a cutting edge technology to combine a novel air-jet method and OCT for assessing the mechanical properties of cornea. This newly invented technology can measure corneal parameters like corneal thickness, optical index, and biomechanical parameters in a non-contact way. It has great potential for corneal assessment in ophthalmology and optometry.

Special Features and Advantages

System is able to provide assessment for cornea in a non-invasive, non-contact and comfortable way.
This newly developed technology can realize corneal biomechanical assessment, structure imaging, and thickness measurement with high resolution.

Applications

It can provide a new technique for corneal biomechanical assessment such as keratoconus disease.
It can also perform corneal structural assessment with its multifunctional features.
