    Patient satisfaction with refractive keratotomy (RK) remained high 3 years post-surgery, with 98% satisfied. However, a significant portion reported persistent visual symptoms, highlighting potential long-term concerns for RK outcomes.

    Area of Science:

    • Ophthalmology
    • Refractive Surgery
    • Patient Outcomes

    Background:

    • Radical keratotomy (RK) is a refractive surgical procedure.
    • Assessing long-term patient satisfaction is crucial for understanding surgical efficacy.
    • The Casebeer nomograms were utilized for RK procedures.

    Purpose of the Study:

    • To evaluate patient satisfaction three years after undergoing radical keratotomy (RK).
    • To assess long-term visual symptoms following RK surgery.
    • To analyze patient willingness to recommend RK surgery.

    Main Methods:

    • A cohort of 96 patients who underwent bilateral distance correction by RK using the Casebeer System were assessed.
    • Patient satisfaction and visual symptoms were evaluated using questionnaires at 3 years postoperatively.

  • A control group of 105 patients awaiting RK surgery completed a preoperative symptom questionnaire.

    • Main Results:

    • 98% of patients reported being very to moderately satisfied with RK at 3 years.
    • 99% of patients indicated they would undergo the surgery again.
    • 69% of RK patients experienced mild to severe postoperative symptoms, compared to 28% in the control group.

    Conclusions:

    • Despite high overall patient satisfaction with RK, a small percentage of dissatisfaction exists.
    • The high rate of persistent visual symptoms warrants consideration in the context of patient expectations and potential legal implications.
    • Long-term follow-up is essential for a comprehensive understanding of RK outcomes.
