Before surgery, patients need to do a comprehensive examination, check corneal topography to see the thickness and regularity of the cornea, check whether there are pathological diseases. Patients with active inflammatory diseases such as acute conjunctivitis, keratitis, dacryocystitis and corneal ulcer are not recommended for patients with dry eye syndrome, glaucoma, trachoma and retinal diseases, Xu said The thickness of the cornea must be able to withstand the correction of myopia. Therefore, the patients with too thin cornea and too high degree should not be operated.
Eye care is important after surgery
I feel the foreign body and feel uncomfortable after the operation for six hours. It also takes a long time for the wound to heal, during which time the eyes must be protected.
Some patients will have dry eye symptoms about three months after surgery. Medicine believes that this is caused by surgery on the corneal subcutaneous nerve damage, dry eyes, the problem is not big, in daily life, pay attention to hot compress, point artificial tears, after a period of time as far as possible to reduce the use of eyes.
