Optiflex angle fixation lens.

C G Munton, M K Tandon

    Journal - American Intra-Ocular Implant Society
    |January 1, 1983

    Summary
    This summary is machine-generated.

    The Optiflex anterior chamber lens showed no corneal decompensation in patients over 18 months. However, corneal astigmatism was identified as a key disadvantage of this intraocular lens.

    Area of Science:

    • Ophthalmology
    • Biomaterials Science

    Background:

    • The development of intraocular lenses (IOLs) aims to restore vision after cataract surgery.
    • Anterior chamber lenses are a type of IOL used in specific surgical scenarios.

    Purpose of the Study:

    • To evaluate the clinical performance and safety of the Optiflex anterior chamber lens.
    • To assess the long-term outcomes, including corneal health and refractive stability, following implantation of the Optiflex lens.

    Main Methods:

    • The Optiflex anterior chamber lens was implanted in 153 eyes of 150 patients.
    • Standard surgical techniques (intracapsular or extracapsular cataract extraction) were employed without adjunctive agents like Healon.
    • Lens surface quality was assessed using scanning electron microscopy.

    Main Results:

    • No instances of corneal decompensation were observed over an 18-month follow-up period.
    • The Optiflex lens demonstrated a good surface finish and an open haptic design.
    • A simple implantation technique was utilized, potentially contributing to the favorable corneal outcomes.
    • Corneal astigmatism emerged as the primary disadvantage associated with the lens.

    Conclusions:

    • The Optiflex anterior chamber lens appears safe regarding corneal health over an 18-month period.
    • The lens design and implantation technique may offer advantages in preventing corneal decompensation.
    • Corneal astigmatism is a significant consideration and potential drawback when using the Optiflex lens.
