Ortho-K, or orthokeratology, is an advanced contact-lens technique that uses rigid gas-permeable lenses overnight to temporarily and reversibly reshape the cornea. The goal is clear daytime vision without glasses or daytime lenses.
Ortho-K can be especially interesting for people with an active life in Barcelona: children, teenagers, students, athletes or adults who want to reduce their use of glasses during the day.
During the night, their special geometry gently redistributes the most superficial layers of the cornea (the epithelium), slightly flattening its central zone. This small optical change compensates for myopia and, often, mild astigmatism.
If you stop wearing the lenses, the cornea gradually returns to its original shape within a few days.
Fitting is always personalised and requires specific tests such as corneal topography.
each pair of lenses is selected or designed based on ocular health, prescription, corneal shape and the patient's lifestyle.
