Dr. Macedo: When we look at orthokeratology research, we are seeing that from 6 to 7 years of age is where myopia starts to progress and when orthokeratology can be started. I would caution against using orthokeratology on very young children. Dr. Dávila-García: Interestingly, most of the studies that are done on myopia management, are based on specific age ranges and this is where the evidence exists. Most studies are with 6 to 12 year-olds.
