1, whether the excimer laser surgery has an impact on the eyes (the LASIK surgery is safe)
A: Excimer laser surgery to correct myopia has a history of more than twenty years, as the laser surgery equipment like other electronic products continue to push the old and new, from the safety and rational more perfect, and laser surgery is external eye surgery, it can be said that his safety is relatively high. However, it is important to know that excimer laser treatment for refractive error is different from doing other eye diseases such as cataracts in that it is an icing on the cake. It requires the surgeon to have a deep knowledge of modern optometry. It can be tailored to fit the patient’s needs and is never a simple surgery. LASIK is a mature technology that has been performed at home and abroad for more than a decade, but there are risks associated with any surgery, and it is possible to obtain satisfactory visual results if the patient is well equipped with experienced surgeons and good equipment, and if the patient cooperates well with the surgeon during surgery. Laser surgery is a safe, reliable and ideal way to treat myopia, and more than 20 million myopic patients have undergone excimer laser surgery worldwide.
2.What kind of people can do excimer laser surgery (conditions for excimer laser surgery) (indications for surgery)
A: Excimer laser surgery indications.
Age 18-55 years old; myopia 50-2000 degrees; astigmatism 600 degrees or less; hyperopia 600 degrees or less; stable refractive status in the past two years; no active eye pathology and systemic diseases affecting the surgical effect; for those who wear contact lenses, they should stop wearing them for a week after examination and treatment.
The effect of surgery will be long-lasting when your preoperative vision is stable for 1 year. We emphasize that the screening of preoperative indications is crucial and must screen out those patients who are implicitly unsuitable for surgery to avoid serious postoperative complications. The U.S. Food and Drug Administration (FDA) has officially determined that excimer laser correction of myopia, hyperopia and astigmatism is a safe and effective method, so you can trust the safety of the procedure itself.
3, after the surgery “rebound”?
A: The rebound we usually talk about is what we call regression and post-operative progress. The difference between regression and progression of myopia should be clear. We say that the excimer laser surgery only takes away your existing prescription, and if your myopia grows again because of improper eye use, this is not a regression.
4.How long does it take to resume normal life after surgery?
Generally, you should put on a transparent eye patch on the day after surgery, but you can also look at objects. The role of the eye patch is because there is a foreign body feeling on the day after surgery, and you are afraid that the object will stimulate the cornea which has not fully recovered. On the second day after surgery, you can remove the transparent eye shield and use your eyes normally! However, within 2 weeks after surgery, you should be careful to avoid the sewage entering your eyes.
5.How does the excimer laser surgery change the vision (the principle of excimer laser surgery)
A: Excimer laser surgery is to change the curvature of the cornea through the energy of the laser and reshape the curvature of the cornea, thus achieving the purpose of treating myopia, hyperopia and astigmatism. In fact, it is the use of high-tech means in the cornea of the human eye to carve a contact lens that will never be removed. Currently, there are two types of excimer laser surgery: one is laser cutting of the corneal stroma; also known as LASIK surgery. The other is the laser cutting under the corneal epithelium, such as PRK, LASEK, EPI-LASIK, etc.
6.What procedures are required to undergo the surgery (pre-operative examination:)
Visual acuity examination
Slit lamp examination
Fundoscopic examination (triple-lens examination if necessary)
Computerized optometry
Comprehensive medical optometry (dilated optometry, primary optometry)
Intraocular pressure
Corneal topography
Corneal thickness measurement
Eye axis
Tear secretion test
Ocular Adjustment Power Analysis
Contrast sensitivity test
Pre-operative examination is completed and then scheduled for registration Antimicrobial eye drops are ordered 3 days before surgery
Scheduled surgery time Post-operative eye drops as prescribed by the doctor Post-operative eye discomfort is only clear
The symptoms will disappear naturally after 1 – 2 days, such as foreign body sensation and tearing.
You can go to work and school normally the next day without hospitalization.
7.Post-operative precautions.
Before surgery, please use eye medication as prescribed by the doctor, in general, 4 times a day for the first week, 3 times a day for the second week, 2 times a day for the third week, and 1 time a day for the fourth week, and then stop the medication or follow the doctor’s advice.
Postoperative day 1, day 3, 7 days, 15 days, 1 month, 3 months, 6 months review, (1 day. 10 days. 1 month. 3 months. 6 months) so that we know. Know the post-operative eye foxing in order to expect to achieve good surgical results.
Do not splash water into your eyes when washing your face and hair for 2 weeks after surgery and do not rub your eyes. Please do not swim for 1 month after surgery, do not use in the eye
Do not use cosmetics on your eyes and avoid foreign objects entering your eyes.
In the early postoperative period, some of you may have difficulty in seeing far and near, and may have uneven vision or double vision, which are normal conditions that may occur during the recovery process.
After surgery, please pay attention to eye hygiene, avoid prolonged close eye use, avoid prolonged reading. Watching TV for a long time may cause visual fatigue and affect the effect of surgery.
