    Area of Science:

    • Ophthalmic surgery
    • Surgical instrumentation
    • Corneal transplantation

    Background:

    • Accurate visualization is crucial for corneal surgical procedures.
    • Existing trephine designs may limit the surgeon's view during critical steps.
    • Improved intraoperative visualization can lead to better surgical outcomes.

    Purpose of the Study:

    • To introduce a new corneal trephine designed for enhanced visualization.
    • To describe the unique structural features of the novel trephine.
    • To highlight the potential benefits of this design in ophthalmic surgery.

    Main Methods:

    • Description of a newly developed corneal trephine.
    • The trephine features a 3-mm cutting ring.
    • It utilizes an open 'branding iron' support structure for visibility.

    Main Results:

    • The new trephine allows surgeons to view the cutting edge circumference.
    • Surgeons can visualize a significant portion of the cornea, lens, and iris.
    • Visualization is maintained while looking through the operating microscope.

    Conclusions:

    • This novel corneal trephine design offers superior intraoperative visualization.
    • The design facilitates improved assessment of the surgical field.
    • Potential for enhanced precision and safety in corneal surgical procedures.
