The after-effects of wearing keratoconus lenses are often not talked about, but mainly about the risks that can occur with wearing keratoconus lenses. First of all, keratoplasty lenses are special contact lenses that require contact with the cornea, so they can have the risks associated with contact lenses. For example, they may cause corneal dehydration and oxygen deprivation, resulting in corneal dryness, dry spots or mild clouding. If they are tightly fastened, they may cause corneal edema if they hinder the process of water absorption by the cornea. Secondly, wearing keratoplasty lenses with a small optical area may cause glare or vision loss in dark environments. Finally, if corneal plastic lenses are not well preserved, they may cause corneal infections and even corneal ulcers, which can be very serious and may cause corneal perforation, and require attention and close follow-up. If you wear keratoplasty lenses, you should follow up every month to check the condition of your cornea, and if you experience redness or pain in your eyes, you should be checked and stop wearing contact lenses.
