    Orthokeratology lens technology has advanced significantly, allowing for tailored astigmatism correction for improved patient outcomes.

  • 2

    Practitioners can now utilize toric reverse and alignment curves to correct more corneal astigmatism and enhance lens centration.

  • 3

    It is recommended to use toric ortho-k lenses when corneal elevation difference exceeds 30 µm at an 8 mm chord.

  • 4

    Under-correcting corneal cylinder is often the most effective treatment to minimize residual astigmatism in ortho-k patients.

  • 5

    Customizing the toricity of ortho-k lenses or using spherical designs can help achieve optimal astigmatism correction.
