MYOPIA MANAGEMENTCASE: Low Myopic Child
Will Skoog OD, FAAO
History
11-year-old white female presented for myopia management consultation. She was in 5th grade. She had read about orthokeratology in a magazine advertisement. Her current spectacles were six months old. She was a competitive swimmer and water polo player. She had no history of myopia management. Her mother was nearsighted and her father wore reading glasses.
Examination

Decision-Making Process
- Need to consider the refractive error and the corneal topography when deciding between myopia management options.
- She was a candidate for all myopia management treatments given refractive error and corneal topography.
- She was a swimmer and water polo player. This positioned orthokeratology at the top of my list.
FItting and Evaluation
- Orthokeratology lenses were fit empirically with refraction, simulated keratometry, and horizontal visible iris diameter (HVID).
- Initial lens parameters:
| Power | BCR | OAD | Material | RZD | LZA | |
| OD | +0.50 DS | 8.7mm | 11.5mm | HDS 100 – Red | 525 | 32/33 |
| OS | +0.50 DS | 8.7mm | 11.5mm | HDS 100 – Blue | 525 | 32/33 |
- Dispense Visit

Clinical Pearls
- It is important to take into consideration the patient’s activities and hobbies when deciding between myopia management options.
- Take multiple topographies per visit!
