MYOPIA MANAGEMENT: Monitoring Progression and Follow-up Schedule

Jessica Liaw OD, FAAO

Monitoring Progression

• Axial length is the most accurate measure for ortho-k myopia control
• CLEERE Study: Axial length growth in emmetropic children¹
  • Ages 6-9: 0.16mm/year
  • Ages 9-12: 0.08mm/year
  • Beyond age 12: 0.02mm/year
• Meta-analyses show a 45% reduction in myopia progression or 0.13mm/year axial length with ortho-k^2,3
• If axial length is unavailable, monitor refractive changes by comparing over-refraction with well-maintained ortho-k lenses each year

Follow-up Schedule

• Evaluate every 3-4 months, minimum six months. Assess the following:
  • Lens condition. Review compliance and safety
  • Topography, visual acuity, refraction, ocular surface staining, biometry
• After one year, an annual examination is necessary for a comprehensive assessment of ocular health
