Excimer laser refractive surgery has been used in clinical practice for 20 years since 1987 and has been performed on more than 20 million people worldwide due to its safety, effectiveness and stability. However, after excimer laser surgery, the central cornea will become thinner and the resistance will definitely decrease. The first thing we need to know about LASIK surgery is that a microkeratome is used to make a circular flap with a tip on the cornea and lift it off, and then laser ablation of the corneal stroma begins. After laser cutting, the tipped flap is reset. The amount of corneal tissue removed during surgery is related to the preoperative myopia, and the greater the myopia, the more corneal tissue is removed. However, corneal tissue cannot be cut uncontrollably, for safety reasons, there is an international safety standard, that is, the thickness of the central residual stromal layer under the flap after LASIK should reach 250um or more, as long as it is above the safety line, the surgery is safe. Secondly, we also need to briefly understand the structure of the eye: the outer wall of the eye is a layer of fibrous membrane, the first 1/6 is the transparent cornea, and the last 5/6 is the opaque sclera, the two migrating parts are called the corneoscleral rim, which protects the integrity of the eye, and the inner layer of the eye wall is the retina, whose role is photoreceptor imaging. Because the cornea is located at the very front, it has a little more chance of being traumatized. The cornea has a certain elasticity and mild external forces are not enough to injure it, but strong contusions or penetrating injuries can rupture the eye, but the common site of rupture is not the center of the thinnest cornea but the corneoscleral junction. As we know in life, the thickness of the door plate is not the first element of safety, the solidity of the door plate and the door shaft connection is more important. But there are still some sports for the general population should not be engaged in, such as boxing. In the boxing match face, especially the eye is the focus of the boxer & ldquo; care & rdquo; place, the chance of danger is very high, in addition there are sports not only myopic people to pay attention to, no refractive error of the population should also pay attention to, such as diving sports, roller coasters and bungee jumping sports, such sports are characterized by high-speed movement in the sudden deceleration and stopping, the main damage to the eyes is to the This makes it easy to understand why divers have a higher chance of retinal detachment than ordinary people. Our Refractive Correction Center has performed refractive surgery on several professional men’s basketball players and women’s soccer players over the years, solving the inconvenience of wearing glasses during training and competition. Post-operative observation so far without any adverse conditions, look at the international sports world famous people such as: golf king Woods, China’s former famous table tennis player Deng Yaping, etc. are myopic people, and have performed excimer laser corrective surgery, in the years of clinical observation, the safety of surgery has been tested. At present, the United States has begun for pilots and astronauts to laser corrective surgery. This shows that for the general population after refractive surgery there is no effect on normal physical activity. Clinically, myopic eyes, especially highly myopic eyes, are prone to degenerative changes in the fundus retina, and the peripheral retina is prone to degenerative dry holes, superficial retinal detachment, vitreous liquefaction, posterior detachment, etc. The posterior detached vitreous repeatedly pulls the retina that has undergone degenerative changes and is prone to fissure, even after laser surgery, the vision is corrected, but the above fundus changes cannot be changed, therefore Even if laser surgery is done to correct the vision, the above mentioned fundus changes cannot be changed, therefore, if you often engage in sports with strong shock and impact to the retina, it is more likely to accelerate retinal detachment. Patients with this type of myopia should minimize such sports, whether or not they undergo refractive surgery. In addition, regular eye examinations should be conducted at the ophthalmology department to detect the lesions early and use laser photocoagulation to prevent retinal detachment. In summary, whether sports are affected after refractive surgery is related to the nature of the sport and the patient’s high refractive error.
