Early after corneal crosslinking, patient crying has an effect that can lead to redness, swelling, eye infections and frequent tearing, which may affect the recovery from the surgery, but late after corneal crosslinking, crying does not usually have an effect. Early after corneal crosslinking surgery, patients crying may affect the health and care of the patient’s eyes after surgery. Patients crying may have bacteria, fungi, parasites and other infections in the eye tissues, causing keratitis or even endophthalmitis. However, in the late postoperative period after corneal crosslinking, the patient’s condition has been stabilized and is usually not affected by crying. It is recommended that post-corneal cross-linking patients follow the doctor’s instructions for care, have regular check-ups, and consult the doctor promptly when discomfort occurs. Patients need to avoid rubbing their eyes with their hands, do not eat spicy and stimulating things and stay up late, do not smoke and drink. After the operation, patients should pay attention to rest and ensure sufficient sleep.
