Myopia surgery consists of two main categories: keratoconus and intraocular refractive surgery. Most people can prevent the occurrence of surgical sequelae through strict preoperative examination and postoperative care. However, a small percentage of patients still experience postoperative sequelae such as dry eye, refractive regression, diplopia, and infection. If there is discomfort after surgery, please seek medical attention immediately and follow the doctor’s instructions for treatment.1. Dry eye: After corneal refractive surgery, some patients will have dry eyes in the early postoperative period, possibly suffering from dry eye. Myopic laser surgery will cut off the sensory plexus within the pre-stromal layer of the cornea, which will lead to reduced corneal perception in the early postoperative period, resulting in a decrease in basic tear secretion, thus making the patient prone to dry eye in the early postoperative period, but over time, most patients can recover on their own; 2. Refractive regression: Refractive power loss occurs again more than 6 months after surgery. Most patients can maintain a good refractive status after laser surgery, but some patients may suffer from refractive regression due to their own reasons or improper eye use; 3, overcorrection or undercorrection: the corrected result may be more than 100° higher or lower than the target after laser myopia surgery; 4, glare and diplopia: symptoms such as glare and monocular diplopia occur, mostly due to the use of a smaller optical ablation area, intended to correct a higher refractive error, or laser ablation off-center; 5, poor visual quality at night: because the pupil is dilated at night, the visual quality at night may become poor, often due to the corresponding detection and design before surgery is not done; 6, corneal plate shift or fold: mostly seen in semi-femtosecond laser surgery or excimer laser surgery, postoperative by external forces and other factors, resulting in corneal flap shift. 7, infection: complications such as corneal infection or corneal clouding, such as improper eye hygiene or other causes of corneal infection; 8, diffuse morning keratitis: the presence of debris between the corneal layers, thus causing diffuse morning keratitis; 9, cataract: patients with crystalline eyes, intraocular implantation of artificial lens, or correction of myopia may develop cataract in the early postoperative period; 10, eye pressure Elevated: Some patients may experience a combination of elevated intraocular pressure after implantation of a crystalline eye or IOL due to changes in atrial fluid circulation pathways.
