Keratoprosthesis: a long-term review.

J J Barnham, M J Roper-Hall

    The British Journal of Ophthalmology
    |July 1, 1983
    PubMed
    Summary

    Artificial corneas (keratoprosthesis) can restore vision in patients with severe corneal opacity. This study found long-term success in many cases, though ongoing monitoring and procedures were often required.

    Area of Science:

    • Ophthalmology
    • Biomaterials Science

    Background:

    • Corneal opacity significantly impairs vision and quality of life.
    • Conventional treatments are often insufficient for severe corneal diseases.

    Purpose of the Study:

    • To evaluate the long-term outcomes of keratoprosthesis (artificial cornea) implantation.
    • To assess visual acuity, vision maintenance, retention rates, and complications associated with keratoprosthesis.

    Main Methods:

    • Retrospective review of 35 patients undergoing 55 keratoprosthesis insertions.
    • Analysis of visual acuity, duration of vision maintenance, device retention, and complication rates.

    Main Results:

    • Successful long-term outcomes were observed in a significant number of patients.
    • Improved vision was maintained in eyes unsuitable for conventional treatments.
    • Complications necessitated careful long-term follow-up and further surgical interventions.

    Conclusions:

    • Keratoprosthesis offers a viable solution for restoring vision in complex corneal conditions.
    • Long-term success is achievable, but requires diligent patient monitoring and management.
