    Summary

    Routine use of a Flieringa ring during large corneal section surgeries improves wound closure accuracy. This method can significantly reduce postoperative astigmatism, enhancing patient outcomes in cataract surgery.

    Area of Science:

    • Ophthalmology
    • Surgical Techniques

    Background:

    • Intracapsular and extracapsular cataract surgeries require precise wound closure.
    • Postoperative astigmatism is a common complication affecting visual acuity after these procedures.

    Purpose of the Study:

    • To evaluate the efficacy of using a Flieringa ring with large corneal sections in cataract surgery.
    • To determine the impact of this technique on wound closure accuracy and postoperative astigmatism.

    Main Methods:

    • Surgical procedures involving large corneal sections were performed.
    • A Flieringa ring was routinely used in conjunction with the corneal section.
    • Wound closure accuracy and the degree of postoperative astigmatism were assessed.

    Main Results:

    • The routine use of a Flieringa ring facilitated more accurate wound closure.
    • A significant decrease in the amount of postoperative astigmatism was observed.

    Conclusions:

    • Employing a Flieringa ring with large corneal sections is beneficial for cataract surgery.
    • This technique enhances surgical precision and reduces visual complications like astigmatism.
