    Radial keratotomy (RK) was a popular surgery for myopia correction, with 250,000 procedures performed annually at its peak in the early 1990s.

    Post-RK patients often experience diurnal refractive fluctuations, with approximately 60% reporting vision changes throughout the day.

  • 3

    A 64-year-old female post-RK patient managed her significant diurnal refractive fluctuations successfully with customized scleral lenses.

  • 4

    The patient's refractive shift was unique as it was hyperopic rather than the typical myopic direction seen in most RK patients.

  • 5

    Scleral lenses provided this patient stable vision and minimized diurnal fluctuations, demonstrating their effectiveness in managing RK-related issues.
