Orthokeratology, often employing specially designed lenses worn during sleep, aims to temporarily reshape the cornea to correct refractive errors like myopia. This modality offers the potential for clear daytime vision without the need for glasses or standard contact lenses. Potential advantages and disadvantages associated with this approach require careful consideration.
The appeal of waking up to corrected vision provides considerable lifestyle benefits, particularly for individuals engaged in active pursuits or professions where eyewear is inconvenient. Historically, the development of rigid gas permeable materials and advanced lens designs has significantly improved the safety and efficacy of corneal reshaping techniques. This has led to increased interest and utilization of this vision correction option.
