5 Key Takeaways

• 1

  Topography is the most informative metric for assessing orthokeratology lens fit, revealing lens behavior and treatment zone details.

• 2

  Tangential maps provide clearer information on treatment zone size and shape, essential for evaluating lens centration and fit.

• 3

  Difference maps are crucial for follow-up visits, showing corneal changes and correlating with spherical equivalent changes.

• 4

  Decentration of treatment zones can enhance myopia control, but not all decentration requires correction if vision remains clear.

• 5

  Mastering map interpretation improves troubleshooting efficiency and strengthens clinical confidence in orthokeratology.
