    Area of Science:

    • Ophthalmology
    • Surgical Technology
    • Corneal Surgery

    Background:

    • Traditional corneal transplantation relies on creating round recipient windows.
    • Current methods often require the incision to be perpendicular to the visual axis.
    • Limitations exist in achieving varied shapes and angles for corneal recipient sites.

    Purpose of the Study:

    • To introduce a new single point cam guided cornea trephine.
    • To enable surgeons to create corneal windows at any angle relative to the visual axis.
    • To facilitate the creation of non-round corneal window shapes.

    Main Methods:

    • Development of a single point cam guided cornea trephine.
    • Utilizing the trephine for creating corneal recipient windows with variable angles and shapes.
    • Exploration of potential future integration with topographical measuring techniques and computer control.

    Main Results:

    • The new trephine allows for cuts at any angle to the visual axis.
    • It enables the creation of round, ellipse, oval, or other non-round corneal window shapes.
    • Frees surgeons from the constraint of perpendicular cuts for round windows.

    Conclusions:

    • The single point cam guided cornea trephine offers enhanced versatility in corneal surgery.
    • Future advancements in topographical measurement and computer integration promise greater precision.
    • This technology has the potential to advance corneal transplantation techniques.
