Objective:

To highlight the importance of understanding corneal metrics for successful orthokeratology (ortho-k) fitting and its impact on patient outcomes.

Approach:

Key Findings:

• Understanding corneal shape, size, and elevation metrics leads to improved ortho-k fitting success and patient satisfaction.
• Corneas with an e-value of 0.50 or higher are likely to achieve greater refractive changes, influencing candidate selection.
• Larger corneas require deeper sagittal heights to avoid inferior decentration, emphasizing the need for precise measurements.

Interpretation:

A thorough understanding of corneal metrics and topography is essential for clinicians to enhance the success rate of ortho-k fittings and improve patient satisfaction.

Limitations:

• The article does not address potential complications or contraindications associated with ortho-k, such as corneal irregularities.
• Individual variations in corneal shape and patient responses are not extensively covered, which may affect fitting outcomes.

Conclusion:

Clinicians should leverage corneal metrics and topography data to optimize ortho-k fitting, ultimately enhancing patient outcomes and satisfaction.
