Clinical Scorecard: Orthokeratology Today
At a Glance
| Category | Detail |
|---|---|
| Condition | Myopia |
| Key Mechanisms | Slows progression of myopia by inducing myopic defocus and reducing axial elongation. |
| Target Population | Patients with low to moderate myopia (–0.50D to –4.50D) and up to –1.50D of astigmatism. |
| Care Setting | Optometry and ophthalmology clinics. |
Key Highlights
- Ortho-k lenses provide a reversible, nonsurgical alternative for vision correction.
- Can slow myopia progression by an average of about 50%.
- Proper lens centration and treatment zone size are critical for effectiveness.
- Smaller treatment zones may enhance myopia control.
- Higher refractive errors may lead to reduced vision due to partial correction.
Guideline-Based Recommendations
Diagnosis
- Assess refractive error and suitability for ortho-k lenses.
Management
- Ensure proper lens centration and appropriate treatment zone size.
Monitoring & Follow-up
- Regular follow-ups to evaluate myopia progression and lens effectiveness.
Risks
- Potential for reduced vision in patients with higher refractive errors.
Patient & Prescribing Data
Children and adolescents with myopia.
Ortho-k lenses are effective in controlling myopia progression while providing daytime vision correction freedom.
Clinical Best Practices
- Customize back optic zone diameter based on individual patient needs.
- Monitor lens centration to ensure optimal treatment outcomes.
- Consider pupil size and refractive status when fitting ortho-k lenses.
