    Ophthalmic Lasers Expand from Surgery to Detection and Diagnosis
    Lasers are an established surgical tool in an ophthalmologist’s armory against glaucoma, cataracts and macular degeneration, but developments in OCT will have doctors turning to lasers before the patient ever reaches the operating room. The development of lasik surgery has led to a rapid growth in the vision correction market over the past two decades. But lasers are now starting to find a place in the early detection and diagnosis of certain eye conditions, particularly when used in optical coherence tomography systems. The first application of femtosecond lasers in ophthalmology was for lasik refractive surgery procedures, in which incredibly ...

    1. These long wavelengths have improved image penetration in scattering tissues...In ophthalmology, there is research interest in using swept-source OCT at 1000 nm because it is less sensitive to cataracts and enables imaging in scattering tissues, such as the choroid, the vascular network behind the retina.
    2. Today there are over 10 companies supplying OCT systems for the ophthalmology and optometry markets. These companies are in fierce fights for market share and are investing lots of development dollars to achieve differentiation and drive sales...As a result, there have been numerous advances in speed, accuracy, higher lateral resolution, higher longitudinal resolution, image processing, compactness, ease of use, functional imaging (e.g., Doppler detection) and lowering capital equipment costs. This has brought, and will continue to bring, benefits to both physicians and end patients.
