  • Full-HD Image Injection Provides a Complete Picture of the Surgical Site Directly in the Microscope Eyepieces

    The human skull is an especially delicate area for surgery. To differentiate healthy tissue from tumor cells, or treat an aneurysm for example, the surgeon needs a complete picture of the surgical area. Supplementary information provided by Image Guided Surgery (IGS) or neuro navigation systems, endoscope, and in some cases fluorescence, can support the surgeon’s visualization, insight and intra-surgical orientation. This supplementary visual information is often only viewable on a separate screen, but with image injection technology from Leica it can be overlaid in full high definition (HD) directly into the eyepieces of a surgical microscope.

  • How to Acquire High-Resolution Anatomic Ocular Tissue Information with Optical Coherence Tomography (OCT)

    Optical Coherence Tomography (OCT) is a non-invasive, non-contact imaging modality used to visualize and monitor changes to the morphology of biological tissue. OCT employs low-coherence interferometry to create cross-sectional images that reveal sub-surface details of the tissues of interest. In the most common ophthalmic applications OCT systems use near-infrared light to generate high-resolution, volumetric images of tissue microstructures including the cornea, iris, crystalline lens, vitreous and retina. These images can enhance insight into pathological conditions such as glaucoma, age-related macular degeneration or diabetic retinopathy.

  • Successful Endodontic Treatment Supported by a Dental Microscope

    In endodontics, accurate treatment is not only dependent on the technical skills and knowledge of the dentist, but also on clear, detailed visualization of the surgical field. As the outcome of an endodontic therapy is influenced by many factors that are not visible to the naked eye – e.g. additional root canals or anatomical variations – the high magnification and illumination provided by a dental microscope has become indispensable for both diagnosis and therapy. Today, it is widely agreed that the use of dental microscopes has helped to extend endodontic treatment potential.

  • "The excellent red reflex, combined with the IOL guidance system, makes it possible for me to work quickly and precisely during refractive procedures."

    Excellent red reflex as well as maximum accuracy throughout the entire procedure are required to meet these expectations. Dr. Ulrich Jung, Medical Director at the ARTEMIS eye clinic in Dillenburg, Germany, tested the Proveo 8 ophthalmological microscope from Leica Microsystems in combination with the positioning system IOLcompass Pro for intraocular lenses at his clinic. In this interview, Dr. Jung reports his experiences.

  • Six Features to Consider when Choosing a Dental Microscope

    In dental medicine, the surgical microscope has become increasingly important for high-quality and successful surgeries, particularly in the field of endodontics. A microscope supports the dentist to conduct micro-invasive surgeries which aim to preserve the tooth substance, conserve the tissue, minimize the risks and reduce healing time. To choose the microscope that best fits the dentist’s needs, it is helpful to know some of the decisive features of a modern dental microscope.

  • How a State-of-the-Art Microscope Helps to Optimize the Workflow in Cataract Surgery

    Typical ophthalmic procedures require specific levels of light, focus and magnification in each phase of surgery. Changing quickly between these settings is the prerequisite for an uninterrupted and smooth workflow where the surgeon can concentrate completely on his patient. The surgical microscope for ophthalmology Proveo 8 features a unique level of customization that allows to program complete surgical phases and single parameters. Dr. Devesh Varma is one of the first ophthalmologists having tested the Proveo 8 microscope.

  • The Impact of a Stable Red Reflex and Enhanced Focus in Cataract Surgery

    In cataract surgery, ophthalmologists rely on the red reflex which provides ideal contrast to visualize the capsule, lens and anterior chamber structure. A new illumination technology in the latest of ophthalmic microscopes now appears to provide great breadth of red reflex enhancement throughout the entire procedure. Dr. Ike Ahmed is one of the first ophthalmologists having tested the Proveo 8 microscope which features the CoAx4 illumination.

  • Cataract Surgery with CoAx4 Illumination

    A stable red reflex is one of the most important features of an ophthalmic surgical microscope for cataract surgery. It’s the red reflex that makes the structure of the lens visible and thus makes for a uncompromised view for a successful and secure surgery. However, conventional red reflex illumination often decreases during the critical phases of the procedure like phacoemulsification. A new illumination technology with four individual beam paths overcomes these drawbacks.

  • Video: Traumatic Soft and Hard Tissue Wound on the Maxillary Anterior with Microscope Assisted Rehabilitation

    The concept of minimal intervention dentistry became a primary approach to treat carious lesions. These days, this concept could be adapted to manage soft tissue around the teeth and implants as a minimally invasive technique. This video, we show a case of traumatic soft and hard tissue wound on the maxillary anterior and its rehabilitation. The patient was a 22 year-old women, and her chief complaint was severe aesthetic disorder because of her trauma. She lost two incisor teeth as well as tissue and bone around the teeth.
