    Subjective refraction techniques have remained largely unchanged since the early 20th century despite advancements in eye care.

  • 2

    Scleral lenses are commonly prescribed for irregular astigmatism, particularly in patients with keratoconus.

  • 3

    Recent algorithm-assisted refraction methods may provide more accurate spherical equivalents compared to conventional techniques.

  • 4

    Variability in subjective refraction results can be influenced by practitioner experience and the limitations of conventional phoropters.

  • 5

    The study suggests that algorithm-based refraction is a viable alternative for optimizing scleral lens fittings in patients with irregular corneas.
