    Summary
    This summary is machine-generated.

    A dull disposable corneal trephine failed to penetrate the recipient cornea during transplantation. Sharpness variations in ophthalmic surgical instruments like corneal trephines can impact surgical outcomes.

    Area of Science:

    • Ophthalmology
    • Biomedical Engineering
    • Materials Science

    Background:

    • Corneal transplantation is a common surgical procedure.
    • Surgical instrument quality is critical for successful outcomes.
    • Disposable ophthalmic surgical tools require stringent quality control.

    Purpose of the Study:

    • To report a case of a dull disposable corneal trephine.
    • To investigate variations in corneal trephine sharpness.
    • To discuss the implications of poor quality ophthalmic instruments.

    Main Methods:

    • A corneal trephine was found to be ineffective during a corneal transplantation.
    • A replacement trephine was used successfully.
    • Scanning electron microscopy (SEM) was employed to assess trephine sharpness.

    Main Results:

    • The disposable corneal trephine was too dull to penetrate Bowman's layer.
    • The replacement trephine was significantly sharper.
    • SEM confirmed appreciable variations in trephine sharpness.

    Conclusions:

    • Inconsistent quality of disposable corneal trephines poses a risk to patients.
    • Sharpness of ophthalmic surgical instruments is paramount.
    • The consequences of substandard surgical tools in ophthalmology warrant further discussion and quality assurance improvements.
