Final answer:
The ideal fluorescein pattern fit for Ortho-K is known as the Bull's Eye pattern, reflecting proper alignment and pressure distribution when fitting Ortho-K lenses.
Step-by-step explanation:
The "ideal" fluorescein pattern fit for Orthokeratology, often abbreviated as Ortho-K, is described as the Bull's Eye pattern. This pattern is considered ideal because it indicates that the Ortho-K lenses are correctly shaping the cornea to correct the patient's refractive error. Unlike the Halo Pattern, Target Pattern, or Starburst Pattern, the Bull's Eye pattern demonstrates a uniform and well-centered distribution of the fluorescein dye under the lens, suggesting good alignment and appropriate pressure distribution across the cornea.
