Marie Freebody, Contributing Editor, [email protected]

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...Read full article

    cornea
    The transparent front layer of the eye. Light entering the eye is refracted (converged) by the outer surface of the cornea.
    excimer laser
    An excimer laser is a type of ultraviolet laser that emits short pulses of light in the ultraviolet spectrum. The term excimer is derived from excited dimer, reflecting the nature of the gain medium used in these lasers. Excimer lasers are widely used in various industrial, medical, and scientific applications due to their ability to deliver high-energy, UV light in short pulses. Key features and characteristics of excimer lasers include: Excimer molecules: The gain medium of an excimer...
    optical coherence tomography
    Optical coherence tomography (OCT) is a non-invasive imaging technique used in medical and scientific fields to capture high-resolution, cross-sectional images of biological tissues. It provides detailed, real-time, and three-dimensional visualization of tissue structures at the micrometer scale. OCT is particularly valuable in ophthalmology, cardiology, dermatology, and various other medical specialties. Here are the key features and components of optical coherence tomography: Principle of...
