Recently, the office of 28-year-old Qing’er lost the sweet smile, a distressed face she is worried, has been wearing myopic contact lenses for 10 years without problems, how a month ago suddenly appeared eye pain, eye red symptoms, professional ophthalmologist told her because of improper care of contact lenses caused by keratitis, the doctor also warned her not to wear contact lenses again, if repeated keratitis may The doctor also warned her not to wear contact lenses anymore, and that if she had repeated keratitis, she might be left with scars on the original clear cornea. What to do? Qing’er was born with big beautiful eyes, and she didn’t want to put a pair of myopic glasses with more than 600 degrees on the bridge of her nose, but she couldn’t wear contact lenses. She was told by her best friend in the office, Cher, to go to the hospital and use excimer laser to treat her myopia, and that would be the end of it. And Cher her sister 3 months ago in a tertiary care hospital just after myopia LASIK surgery, now both eyes bare eye vision in 1.2 or so. ”Really? I can try it too! Now the doctor says my cornea has recovered as it was thanks to timely treatment.” Qing’er’s heart was overjoyed. The next day, Qing’er came to a tertiary hospital refractive surgery specialist examination with hope, after a detailed examination of 10 items before and after again made Qing’er confused, the doctor said Qing’er cornea is too thin, can not do LASIK surgery, but can choose to do LASEK surgery. What is the difference between these two types of surgery? The patient and amiable deputy chief surgeon let her watch a video demonstration of the surgery and explained in detail: (i.e. Excimer laser in situ keratomileusis) is performed by a surgeon using an automatic micro lamellar keratome to create a 100-130µm thick tipped corneal flap on the cornea, then excimer laser cutting is performed on the corneal stromal bed under the flap according to the designed degree of myopia. The flap is reset and the cornea heals within 24 hours. After the surgery, the flap is reset and the cornea heals within 24 hours. The postoperative period is basically painless and the recovery of vision is fast, and the best corrected vision can be achieved on the first day after surgery or close to the preoperative period. However, LASIK is associated with the risk of flap fabrication and potential flap-related complications, and LASIK limits the correction of thin corneal myopia because of the influence of corneal thickness. （LASEK is a modified version of PRK (excimer laser refractive keratomileusis). The most important feature of LASEK is to create and preserve an intact corneal epithelial flap by applying 20% ethanol to infiltrate the corneal epithelium, lift the flap and perform excimer laser cutting on the underlying anterior corneal elastic layer according to the designed myopia, then reset the corneal epithelial flap and wear a The LASEK technique requires a high level of surgical skill, with lacrimation and mild discomfort on the day after surgery and significant improvement on the second day, slow recovery of vision compared to LASIK, and longer medication time, but has the advantage of being very safe. myopic patients with high risk (e.g. sports, punchy confrontational practitioners). Combined with our special national conditions, young people with mild myopia, or astigmatism who require laser surgery for reasons such as military enlistment or job recruitment are also preferred indications. The surgery was performed in a relaxed and interactive atmosphere, and the surgeon’s skillful surgical technique and kind words helped her to complete the surgery in 10 minutes without any pain. After the surgery, she wore special therapeutic contact lenses for both eyes. At the end of the surgery, she was personally instructed by a very responsible surgeon on how to apply eye drops after the surgery, which made her feel very excited. The next day after the surgery, she woke up and opened her eyes: “Wow, I can see the second hand of the clock on the wall”. I’ll take off your therapeutic contact lenses in 1 week, and you must follow the doctor’s instructions on eye drops. ”Can I participate in various sports in the future?” The main surgeon said, “Yes, the LASEK surgery is safe, you can swim or ski after 3 months, but of course, you have to be careful not to hurt your eyes with violence”. On the third day, Qing’er returned to her office in the skyscraper and looked out the window, the clear green trees and blue sky were so lovely, so refreshing.
