Orthokeratology, or ortho-k, is the use of specially designed and fitted contact lenses to temporarily reshape the cornea to improve vision. It’s like orthodontics for your eyes and the treatment is often compared to dental braces.
Orthokeratology (ortho-k) is the fitting of specially designed gas permeable contact lenses that you wear overnight. While you are asleep, the lenses gently reshape the front surface of your eye (cornea) so you can see clearly the following day after you remove the lenses when you wake up.
Orthokeratology is a nonsurgical process, using hard contact lenses, which temporarily corrects refractive errors like myopia and astigmatism in both children and adults. Learn more about how the procedure works as well as associated side effects and risks.
Orthokeratology, also referred to as Night lenses, Ortho-K, OK, Overnight Vision Correction, Corneal Refractive Therapy (CRT), Accelerated Orthokeretology, Cornea Corrective Contacts, Eccentricity Zero Molding, and Gentle Vision Shaping System (GVSS), is the use of gas-permeable contact lenses that temporarily reshape the cornea to reduce ...
Orthokeratology, often called Ortho-K, is a safe, FDA-approved treatment that temporarily reshapes your cornea while you sleep. Here’s the key idea: It uses unique, rigid gas-permeable contact lenses that you wear only at night. These lenses apply gentle pressure to your cornea, subtly flattening its central area.
Orthokeratology is the temporary reduction of myopia achieved by the programmed application of contact lenses to reshape the cornea. Modern orthokeratology achieves this using specially designed reverse geometry gas permeable (GP) ortho-k shaping lenses worn during sleep. This overnight wearing process provides a faster, more
Orthokeratology: Principles, Lessons, Cases. Learn how to best apply this modality for myopia control and more. By Priscilla Chang, OD. Orthokeratology’s (ortho-K) resurgence in popularity is a testament to extensive research efforts, lens design advancements and our growing understanding of the corneal shape and topography.
ortho-k (short for orthokeratology) is a non-surgical procedure using specially designed contact lenses to gently reshape the curvature of the eye to improve vision. This is a revolutionary non-surgical procedure that eliminates the need for glasses or daytime contact lenses.
Orthokeratology (ortho-k) is a special rigid contact lens worn at night to achieve myopic reduction and control. This review provides an overview on prescribing ortho-k, including clinical consideration on patient aspect and lens design; its clinical outcomes; and clinical efficacy and safety.
Orthokeratology involves wearing a specially-designed rigid contact lens overnight. Like a mold, the lens temporarily reshapes the eye while you sleep by gently changing the profile...
