    Area of Science:

    • Ophthalmology
    • Microsurgery

    Background:

    • Traditional needles can cause tissue compression and astigmatism during wound closure.
    • Cataract, keratoplasty, and traumatic corneal wounds require precise surgical techniques.

    Purpose of the Study:

    • To introduce and evaluate the bicurved fish hook needle for corneal wound closure.
    • To assess the needle's ability to minimize tissue compression and induced astigmatism.

    Main Methods:

    • Utilizing a bicurved fish hook needle for suturing corneal wounds.
    • Comparing outcomes with traditional single-radius needles.

    Main Results:

    • The bicurved needle facilitates consistent, short bites.
    • Minimal tissue compression and astigmatism were observed.
  • The handling technique is easily learned.

    • Conclusions:

    • The bicurved fish hook needle is effective for closing corneal wounds with reduced complications.
    • Its application may extend to other microsurgical procedures like vascular anastomosis.
