The broken nylon iris fixation suture

B E Cohan

    American Journal of Ophthalmology
    |April 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Nylon sutures for intraocular lenses fractured in 26.9% of cases, potentially causing lens dislocation. Routine follow-ups can detect breaks, and laser shrinkage is a viable treatment option.

    Area of Science:

    • Ophthalmology
    • Biomaterials Science

    Background:

    • Intraocular lens (IOL) implantation is a common procedure.
    • Suture material choice is critical for IOL stability and long-term outcomes.
    • Nylon sutures have been used for IOL fixation, but their long-term integrity is a concern.

    Purpose of the Study:

    • To evaluate the incidence and consequences of nylon suture breakage in Worst intraocular lens fixation.
    • To determine the clinical significance of nylon suture failure in IOL support.

    Main Methods:

    • Retrospective analysis of 216 eyes implanted with Worst intraocular lenses secured by nylon sutures.
    • Documentation of suture integrity, IOL position, and any related complications during follow-up examinations.

    Main Results:

    Related Experiment Videos

    • Nylon sutures broke in 58 out of 216 eyes (26.9%).
    • Complete lens dislocation occurred in two cases secondary to suture failure.
    • No immediate recall was deemed necessary for patients with nylon sutures.

    Conclusions:

    • Nylon sutures demonstrate a significant rate of breakage when used for Worst IOL fixation.
    • While not requiring special recall, broken sutures discovered during routine exams warrant consideration for laser shrinkage.
    • Laser shrinkage presents a potential management strategy for identified nylon suture dehiscence.
