Excimer laser surgery is a highly elective procedure, and although years of clinical practice and millions of clinical outcomes worldwide have proven that excimer laser surgery is by far the safest and most effective refractive surgery, it is important to remember that the “safety and effectiveness” of excimer laser surgery is based on detailed preoperative examinations, proper surgical design, skillful However, it must be reminded that the “safety and effectiveness” of excimer laser surgery is based on detailed preoperative examination, proper surgical design, skillful surgical techniques, high-quality surgical equipment and perfect postoperative follow-up. In general, the level of excimer laser surgery in China has kept pace with the world’s advanced level and is in a rapid and steady development. However, there is a big gap in the overall medical level in China, and some medical institutions with low level and poor conditions (including hardware and software) are also carrying out excimer laser surgery. Failure cases, the vast majority of which occur there, are due to the inexperience of their surgeons, irregular operation procedures, backward equipment (even the introduction of foreign eliminated equipment), and low-price competition, which directly lead to the decline of medical quality and the success rate of surgery is far from the same. Therefore, it is recommended that the patient should keep a clear head and not be confused by the “low price”, but should choose a hospital with guaranteed quality and a skilled surgeon for the surgery. Choosing the right hospital and the right doctor is the first condition to ensure safety. Excimer laser surgery uses a cold laser to scan the cornea on the surface of the eye, which will not hurt the internal tissues of the eye. The equipment used in our hospital is the world’s most advanced “small spot high-speed flying spot scanning” excimer laser system, which is fully computer-controlled, with high-speed automatic tracking, and can perform personalized cutting, and has a computerized self-control system, which will automatically stop the surgery if an accident occurs. If an accident occurs, the surgery will be stopped automatically, which is not possible with traditional equipment. Our surgeons are experts in ophthalmic excimer laser surgery and are experienced in surgery.
