Early experience with STAAR silicone elastic lens implants.

G D Faulkner

    Journal of Cataract and Refractive Surgery
    |January 1, 1986

    Summary

    Silicone elastic intraocular lens implants improved vision in most patients. Avoiding in-the-bag placement prevented implant decentration and tilting, the only significant complication observed in this study.

    Area of Science:

    • Ophthalmology
    • Biomedical Engineering
    • Materials Science

    Background:

    • Cataract extraction with intraocular lens (IOL) implantation is a common surgical procedure.
    • Silicone elastic IOLs offer specific biomechanical properties for implantation.
    • Understanding IOL behavior within the eye is crucial for surgical success.

    Purpose of the Study:

    • To evaluate the clinical outcomes of STAAR Model B silicone elastic intraocular lens implants.
    • To identify any complications associated with this specific IOL model.
    • To determine optimal surgical placement techniques for silicone IOLs.

    Main Methods:

    • Extracapsular cataract extraction with phacoemulsification was performed on 18 human eyes.
    • STAAR Model B silicone elastic intraocular lenses were implanted.
    • Postoperative visual acuity and IOL position (centration and tilt) were assessed.

    Main Results:

    • 17 out of 18 eyes achieved a visual acuity of 20/40 or better without preexisting pathology.
    • Implant decentration and tilting occurred in five of six eyes with in-the-bag placement.
    • No other significant complications were noted.

    Conclusions:

    • STAAR Model B silicone elastic IOLs provide good visual outcomes following cataract surgery.
    • In-the-bag placement is associated with a high risk of implant decentration and tilt.
    • Avoiding in-the-bag placement is recommended to prevent IOL displacement complications.
