Intraocular lens quality control

R J Olson, A S Crandall, R C Welch

    Journal - American Intra-Ocular Implant Society
    |January 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Mislabeled intraocular lenses (IOLs) and poor loop quality highlight the need for vigilance. Surgeons must ensure IOL manufacturers maintain high standards for accuracy and quality.

    Area of Science:

    • Ophthalmology
    • Medical Device Quality Control

    Background:

    • Intraocular lens (IOL) implantation is a critical step in cataract surgery.
    • Ensuring the accuracy and quality of IOLs is paramount for successful surgical outcomes.

    Purpose of the Study:

    • To highlight instances of IOL mislabeling and manufacturing defects.
    • To emphasize the importance of ongoing quality control by implant surgeons.

    Main Methods:

    • Optical bench testing of explanted or suspect intraocular lenses.
    • Visual inspection of lens component quality, specifically loop integrity.

    Main Results:

    • One mislabeled lens showed a measured diopter power of 19.66D, significantly differing from its labeled 13.00D power.

  • Three consecutive posterior chamber lenses from a single manufacturer exhibited poor loop quality.

    • Conclusions:

    • Deviations in IOL power and defects in physical quality can lead to surgeon and patient dissatisfaction.
    • Continuous monitoring of IOL manufacturers by implanting surgeons is essential to guarantee implant accuracy and quality.
