Corneal opacities are eye diseases caused by keratitis, corneal trauma, corneal degeneration, malnutrition, etc. For corneal opacities caused by keratitis, patients can use tobramycin eye drops for treatment to control inflammation. Corneal opacities belong to a kind of corneal clouding, corneal opacities caused by keratitis can be treated with antibiotic drugs such as tobramycin eye drops to control the inflammation and promote corneal clouding to subside. However, if the corneal opacities are caused by other reasons such as corneal degeneration and malnutrition, the treatment with tobramycin eye drops or ointment is not effective. If the corneal opacities are located in the center of the cornea and severely affect the patient’s vision, surgical treatment such as corneal transplantation is feasible. It is recommended that patients with keratoconus should consult a doctor in time to evaluate their condition and follow the doctor’s instructions for treatment.
