It was once the childhood dream of many Chinese heroes to enter the military and put on the dark green uniform. However, due to myopia, many young people can only bury their dreams of military service in the bottom of their hearts. As the annual draft is about to begin, many aspiring young people are worried because of their eyesight problems, thinking about their dream military camp and looking at their thick glasses. Not only is this true for the military, but also for college, as an actor, athlete, flight attendant, etc. They also face the same threshold of vision. It’s a shame that opportunities pass by simply because of vision problems. Fortunately, medical technology is advancing rapidly, and keratomilecular refractive surgery made a breakthrough in the 1980s with the application of excimer laser technology. Excimer laser LASIK and LASEK surgery are currently the world’s most mature methods for correcting myopia and astigmatism, allowing myopia to be removed and normal vision restored once and for all. Also known as excimer laser in situ keratomileusis, a micro lamellar keratome is used to make a tipped flap of a certain thickness, then the flap is lifted to expose the corneal stroma, and then a computer-controlled excimer laser is used to perform precise cutting, grind part of the corneal stroma, and finally reset the flap. There is a slight discomfort of 2-3 hours after the surgery, and vision recovery is fast, usually only about 1 day. So is it safe to choose to have LASIK surgery as a soldier? After all, soldiers need to go through a variety of physical and combat training, I have encountered several cases of young men who just had LASIK surgery to go into the military, due to accidental injuries to the eye during the training process led to a displacement of the corneal flap and seriously affect vision and the need for re-operation. Therefore, myopic patients who choose LASIK surgery should avoid accidental violence to the eye after surgery. In fact, LASEK (excimer laser epithelial subsurface keratomileusis) is safer and more resistant to strenuous sports and external forces than LASIK. Because LASEK does not use a microkeratome to cut the cornea, the risk is low. LASEK is performed by infiltrating the corneal epithelium with an appropriate concentration of ethanol, creating and preserving an intact epithelial flap, lifting the flap and performing excimer laser cutting on the anterior corneal elastic layer underneath at the designed myopic degree. The most important feature of LASEK is the creation of a complete corneal epithelial flap, which significantly reduces postoperative pain and speeds up the recovery of vision. This new technology requires a high level of surgical skill and has the advantage of being very safe, making it a better choice for practitioners with high levels of confrontation, such as soldiers and athletes. In addition, it should be reminded that those who want to be in the military should have the surgery as early as possible before the medical examination, at least 2-3 weeks, because there is a foreign body sensation, tearing, mild soreness, etc. within 1-2 days after LASEK surgery, and it takes 5-7 days to remove the protective contact lenses, and the vision recovery is slower compared to LASIK. In conclusion, the primary goal of excimer laser myopia correction surgery is to improve naked eye vision and remove the dependence of myopic patients on glasses. Before surgery, a detailed pre-surgical examination is required, including a comprehensive examination of naked eye vision, visual acuity with glasses, ophthalmic slit lamp examination, primary eye, medical optometry, contrast sensitivity, intraocular pressure, eye axis, corneal endothelium, central corneal thickness measurement, rapid dilated pupil examination, wavefront aberration, and fundus trifacial lens. Strict preoperative examination and evaluation, reasonable surgical design, standardized operation procedure and postoperative medication, and perfect follow-up system are the important guarantees for high quality surgical efficacy.
