Myopia surgery, also known as myopia surgery, is also a type of surgical procedure, so there are certain risks involved no matter what type of myopia correction surgery is chosen to be performed. Certain sequelae can arise from inadequate preoperative examinations, improper handling by the surgeon during surgery, the patient’s eyes moving about during surgery, or the occurrence of infection. In mild cases, this may lead to surgical failure and complications of inflammation, and in severe cases, it may lead to impaired vision and even blindness: 1. Dry eye syndrome: Some patients will experience dry eye syndrome after myopia surgery, which can easily lead to dry eyes and fatigue. Most of the dry eyes caused by surgery can be recovered by using eye drops and other medications, while some patients’ dry eye conditions may last longer or even fail to recover; 2. Glare: Patients who have experienced myopia surgery have larger pupils, which can lead to glare, halos or double vision, which is more common at night. However, most patients’ glare will improve over time until it is restored; 3. Keratitis: Improper post-operative care or improper eye hygiene may lead to eye infection, which may cause keratitis; 4. The stability of the cornea is reduced, and patients with a large preoperative myopia have a greater chance of rebound after surgery. Patients are advised to use medications as prescribed by their doctors, pay attention to eye hygiene and post-operative care, and keep their eyes well rested to avoid eye fatigue. Myopia surgery is clinically mature, and although risks and sequelae exist, they are less likely to occur, so you should choose a professional hospital with perfect medical resources and mature doctors before surgery.
