A return to primitive practice? Radial keratotomy revisited.

J P Bergmanson, E J Farmer

    Contact Lens & Anterior Eye : the Journal of the British Contact Lens Association
    |November 24, 2005
    PubMed
    Summary

    Radial keratotomy (RK) is not superior to laser vision correction like photorefractive keratectomy (PRK) and laser assisted in situ keratomileusis (LASIK). RK leads to significant long-term visual and corneal health complications compared to laser procedures.

    Area of Science:

    • Ophthalmology
    • Refractive Surgery
    • Corneal Health

    Background:

    • A recent public recommendation favored radial keratotomy (RK) over laser procedures (PRK, LASIK) for better visual outcomes and fewer complications.
    • This study evaluates the scientific literature to validate claims comparing RK, PRK, and LASIK efficacy and safety.

    Discussion:

    • Current peer-reviewed data do not support RK's superiority in visual outcomes compared to PRK and LASIK.
    • While precise complication rates are challenging to ascertain, chronic effects reveal significant visual quality impairment and corneal health issues in post-RK patients.

    Key Insights:

    • Visual acuity outcomes for low to moderate myopia are comparable across RK, PRK, and LASIK.
    • Radial keratotomy (RK) is associated with substantially higher long-term visual and corneal health complications than laser-based refractive surgeries.

    Outlook:

    • Radial keratotomy (RK) is not recommended as a preferred refractive surgery methodology due to its chronic complications.
    • Further research may focus on long-term comparative analyses of newer refractive techniques and their impact on ocular health.
