Keratoplasty lenses, also known as OK lenses, can prevent and control the progression of myopia to a certain extent, with prices ranging from a few thousand dollars domestically and tens of thousands of dollars for imported OK lenses. Keratoplasty lenses are customized corneal rigid contact lenses, which are more expensive due to their complex process, low production, the need to customize them according to the specific conditions of the individual, and the period of use of about one and a half years, and the need for regular review and care. Domestic keratoplasty lenses mostly cost 7,000 to 8,000 dollars as a starting price, while most imported keratoplasty lenses cost tens of thousands of dollars. The specific price of OK lenses and the price of post-care and review may vary depending on the individual’s situation, so it is recommended to choose a reliable eyeglass dispensing organization and make a choice based on your own financial situation and realistic needs.
