Corneal reshaping treatments, also known as orthokeratology or corneal refractive therapy (CRT), are non-surgical vision correction methods that use specially designed gas-permeable contact lenses to reshape the cornea. This process allows for clear vision throughout the day without the need for glasses or contact lenses. The lenses are worn overnight, applying gentle pressure to the cornea, which gradually reshapes it to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The effects are temporary, and the cornea returns to its original shape if the lenses are not worn regularly. This method is particularly beneficial for children and adults who prefer not to wear corrective eyewear during the day.
