Wearers of Keratoplasty lenses should be aware of the need to be of a certain age, be careful not to scratch the cornea when wearing, clean hands before wearing to avoid infection, and keep up with their checkups. Keratoplasty lenses, also known as corneal contact lenses, are gas permeable rigid contact lenses. Keratomileusis corrects refractive errors by improving the shape of the cornea and reducing its refractive power. Keratoplasty is a non-surgical way to improve refractive error. Keratomileusis wearers should be at least 8 years old. As keratoplasty lenses are hard contact lenses, care should be taken not to scratch the cornea when wearing them. Before wearing the lenses, you should wash your hands and disinfect them, as well as pay attention to the protection of the lenses, so as not to allow bacteria to contaminate the cornea, causing keratitis and other diseases. When wearing keratoplasty lenses, you should pay attention to review on time, wear appropriate keratoplasty lenses, and stop the operation immediately after wearing the discomfort.
