5 Key Takeaways

• 1

  Orthokeratology (ortho-k) effectively slows myopia progression by inducing peripheral myopic defocus, reducing axial length elongation by 36% to 46%.

• 2

  Slit lamp imaging and topography are essential tools for evaluating ortho-k lens fits, enhancing fitting efficiency and patient outcomes.

• 3

  Dynamic fluorescein evaluation reveals an ideal ortho-k lens fit through a characteristic bull’s-eye pattern, indicating proper centration and alignment.

• 4

  Corneal topography allows for empirical fitting of ortho-k lenses by providing critical data on corneal curvature and facilitating lens customization.

• 5

  A smaller back optical zone diameter of 5.0 mm in ortho-k lenses has been shown to improve myopia management efficacy significantly.
