Excerpt

OCT technology has been utilized successfully for anterior segment evaluation, offering several clinically relevant applications. Its capabilities allow for non-contact imaging, detailed visualization and analytics of anterior segment structures of the human eye on one device. These structures include the cornea, anterior chamber, iris, and lens. The SPECTRALIS Anterior Segment Module, based on spectral-domain OCT and an 880 nm light source, allows for high axial resolution images of anterior segment structures. The ANTERION is a swept-source OCT device with a 1300 nm light source, which allows for the acquisition of high-contrast anterior segment images along a large image depth. Swept-source OCT technology combined with a longer wavelength light source can also serve as a tool to measure the axial length of the human eye. The above-mentioned structures and parameters are used in ophthalmology for corneal topography, corneal tomography, anterior segment analysis, biometry and calculation of intraocular lens power, as well as many other possible clinical applications.
