    Area of Science:

    • Ophthalmology
    • Biomedical Engineering

    Background:

    • The 1990 literature review highlights significant advancements in intraocular lens (IOL) technology.
    • Increased popularity of phacoemulsification spurred interest in small-incision lens designs and soft lens folding techniques.

    Purpose of the Study:

    • To review and evaluate the state of intraocular lens technology and its applications as of 1990.
    • To assess the benefits, drawbacks, and candidate suitability for multifocal intraocular lenses.
    • To examine new developments in lens materials, surgical techniques, and patient outcomes.

    Main Methods:

    • Literature review of 1990 publications on intraocular lenses.
    • Evaluation of clinical data and outcomes for various IOL types, including multifocal, anterior chamber, and posterior chamber lenses.

  • Assessment of new technologies such as heparin surface modification and scleral suturing techniques.

    • Main Results:

    • Multifocal lenses showed improved understanding of their pros and cons, with developing guidelines for patient selection.
    • Heparin surface modification of polymethylmethacrylate lenses demonstrated value in reducing postoperative pigment deposits.
    • Anterior chamber lenses for high myopia were put on hold due to concerns about endothelial cell loss; scleral-sutured posterior chamber lenses gained attention for complex cases.

    Conclusions:

    • Intraocular lens technology continued to evolve rapidly in 1990, with increased global usage.
    • Ongoing research and clinical trials, particularly for age-related macular degeneration, hold promise for future IOL applications.
    • Careful patient selection and ongoing evaluation of lens safety and efficacy remain critical.
