    An Introduction to Refractive Surgery

    The concept of laser vision correction surgery has been around since the early 1990s, and advancing technologies have made the procedure safer and more effective. The introduction of femtosecond lasers has made the procedure safe and more precise, while imaging technologies have allowed customized maps of the cornea, to reduce higher-order aberrations that cause adverse effects such as glare and halos.

    Browse the content below, to see leading experts discuss the latest data in video interviews and short articles from our conference hub. You can also view the selection of peer-reviewed articles from our journals. If you’re looking to learn more about the impact of these developments on patient outcomes, our educational activities are a great resource.

    Vector Planning: Treating Asymmetrically and Achieving the Minimum Refractive and Regular Corneal Astigmatism
    Noel Alpins

    touchREVIEWS in Ophthalmology. 2024;18(1):41-45

    The demands for refractive surgery weigh on achieving the best unaided vision postoperatively. This, in many clinics, lines up with achieving a plano or minimal spherocylindrical manifest refraction. However, in my experience, many patients are complaining of blurred vision after refractive laser surgery and yet can still read the 6/6 or 20/20 line on a […]
