Orthokeratology, commonly called ortho-k, uses specially designed contact lenses worn during sleep to temporarily reshape the cornea. The approach provides an alternative to daytime corrective lenses and is also being studied as a strategy for managing myopia progression.
The orthokeratology lens market includes custom-designed lenses manufactured according to individual corneal characteristics.
Unlike conventional contact lenses that primarily correct vision while being worn, orthokeratology lenses are generally worn overnight and removed during the day.
Advances in corneal mapping and lens manufacturing are helping practitioners develop more customized designs. Digital imaging can support more accurate fitting and monitoring.
Myopia management is becoming an increasingly important application, particularly among children and adolescents. Increasing awareness of myopia progression and its potential long-term consequences is encouraging interest in non-surgical approaches.
The market also benefits from growing consumer interest in alternatives to glasses and conventional contact lenses.
However, proper fitting and patient monitoring are essential. Eye-care professionals must evaluate corneal health and ensure that lenses are used appropriately.
Material development is another area of innovation. Highly gas-permeable materials are important because lenses are worn during sleep and need to support adequate oxygen transmission.
As awareness of myopia management increases, orthokeratology could become a more prominent component of the vision-care landscape.
