Why does the corner of your eye itch every day when you wear corneal reshaping lenses?

Itchy corneal corners after wearing keratoplasty lenses may be caused by dry eyes or mild allergies.
Keratoplasty is a rigid corneal contact lens, so unskilled or prolonged wear may lead to corneal epithelial damage or tear film instability, both of which can lead to dry eye.
Dry eye can lead to dry and itchy eyes, and in severe cases, there may be redness and tearing of the eyes.
Keratoplasty lenses need to be cleaned and preserved with a special care solution, which is usually neutral and non-sensitizing, but mild allergy to the care solution cannot be ruled out if the child is allergic.
If you experience itchy eyes for a long time after wearing keratoplasty lenses, it is recommended to consult an ophthalmologist, and ophthalmic medication can be used as prescribed by the doctor.
