Ortho-K provides freedom from daytime eyewear and suits active lifestyles.
Orthokeratology is suitable for people with mild myopia or low levels of astigmatism. Candidates should have healthy eyes, proper tear production, and commitment to nightly wear and follow-up visits. Children with progressing nearsightedness often benefit from early intervention.
