Patients who develop corneal scarring can be observed and followed if it does not affect their vision. If corneal scarring significantly affects the patient’s vision, and medication is generally ineffective, the patient may be treated surgically to improve vision, such as corneal transplantation. If the patient’s corneal scar is thin and located in the periphery, the impact on the patient’s vision is small, and clinical observation is generally considered. However, if the corneal scar is located right in the pupil area, which has a significant impact on the patient’s vision, the patient can use surgical treatments, such as corneal lamellar transplantation or corneal allotransplantation, as prescribed by the doctor. It is recommended that patients with corneal scarring and associated vision loss seek prompt medical attention to evaluate their condition and follow the doctor’s instructions.
